Figure 2 shows a hardware photo of the evaluation board. Figure 3 shows a block diagram of the main components on the board. The circuit is designed to provide a rated load of 12 V, 20 A from a dc input voltage source of 36 V dc to 75 V dc. The ADP1051 provides functions such as output voltage regulation, synchronization, constant current control, prebias start up, direct paralleling, and comprehensive protection. The main transformer on the evaluation board breaks the dc-to-dc power supply into primary side and secondary side; therefore, creating isolation. On the primary side, the full bridge stage switches and inverts the dc voltage derived from the input terminals (J1 and J5) into ac voltage. The control signals for the full bridge stage come from the ADP1051 through the digital isolators (ADuM3210) and the half bridge drivers. There is also a current transformer (CT) sensing and transmitting the primary side current information to the ADP1051 on the secondary side. On the secondary side, the full wave synchronous rectifiers (SR) rectify the ac voltage to dc voltage. An LC filter smooths the pulsated dc voltage. The current information is sensed through a current sense resistor and fed to the CS2+ and CS2− pins in the ADP1051. Output terminals, J2 and J6, are used for the load connection. An auxiliary power supply on the evaluation board is used to generate a 10V_PRI bias power for full bridge drivers, a 5V_PRI bias power for the primary side power supply of the ADuM3210, and a 10V_SEC bias power for the ADP3654 driver. A 10V_VCC bias power is generated from an OR-diode network using a 10V_SEC bias power and 5 V voltage source from the USB-to-I2C connector. This allows the GUI access to the ADP1051 when the auxiliary power circuit is not powered up. The ADP3303 LDO converts 10V_VCC to a 3V3_SEC bias power for the ADP1051 and the secondary side power of the ADuM3210. Alternatively, the auxiliary power input can also come from an independent dc source through TP47 and TP50. An analog current share connector (J15) allows an external current share daughter card to be used for analog current sharing control. Two parallel connectors (J17 and J18) allow the synchronization, current share, and PMBus communication between multiple evaluation boards. There are wholly three blue color LEDs in the evaluation board to provide the status of the evaluation board. D7 indicates the input voltage signal. D17 indicates the PGOOD output (PG/ALT pin output signal). D18 indicates the FLAGIN signal. There are three complete switches on the evaluation board. The SW1 switch is used to control the voltage level of the hardware CTRL pin. The SW2 and SW3 switches are used to change the part operating state between as master device and as slave device when the synchronization is enabled. The ADP1051DC1-EVALZ daughter card shown in Figure 4 can be plugged into the daughter card connector (J8). It provides the signals that are used to regulate the output voltage, limit the output current, and control the on/off switch of the evaluation board. A 4-pin connector (J2) on the daughter card is used for I2C/PMBus communication through a USB-to-I2C connector, ADP-I2C-USB-Z. This allows the GUI software to communicate with the evaluation board through the USB port of the PC. If the J17 or J18 parallel connector is connected, the GUI can visit all the evaluation boards through a single USB-toI2C connector. With this interface, users can monitor and program the ADP1051.

Enable the SR soft start and select a different SR soft start speed to prevent a glitch at the output voltage ramp. UG-566 Evaluation Board User Guide PWM SETTINGS Although the switching frequency can be adjusted, the GUI software does not account for the dead times and the PWM timings have to be programmed manually to guarantee the normal operation of the PWM outputs. 11529-022 The PWM timings for the primary side switches and secondary side synchronous rectifiers are programmed in the PWM SR Settings window of the Setup tab as shown in Figure 21. This window allows the programming of the switching frequency, rising edge and falling edge timings, the type of modulating edge (rising edge or falling edge), modulation type (positive or negative), and modulation limit. Figure 21 shows the gate drive signals at the output pins of the ADP1051. The QA, QB, QC, QD, Q7/Q8, and Q3/Q4 switches in the evaluation board ADP1051-240-EVALZ are driven separately by PWM outputs OUTA, OUTB, OUTC, OUTD, SR1, and SR2. Figure 22. Adaptive Dead Time Compensation Settings Window DIGITAL COMPENSATOR AND LOAD TRANSIENT RESPONSE 11529-021 The digital compensator can be configured by the Filter Settings window of the Setup tab as shown in Figure 23. The digital compensator can be changed by manipulating the position of the poles and zeros in the s-domain. The ADP1051 allows two different sets of compensator responses to be programmed. One is normal mode compensator and the other is light load mode compensator. The digital compensator is a Type III compensator. The first pole is placed at a dc position to eliminate the steady state error. The second pole can be freely placed (ideally at the ESR zero position). However, the third pole is fixed at half of the switching frequency. Figure 21. PWM SR Settings Window Enable and disable the pulse skipping mode and measure the standby power of the PSU. Double the switching frequency from 120 kHz to 240 kHz. The board is designed to operate at a switching frequency of up to 240 kHz with airflow cooling. Program an imbalance in the on time of the QA and QC switches, and evaluate the volt-second balance control function. Run the software in simulation mode and program the PWM settings for different topologies such as zero-voltageswitched full bridge, hard-switched full bridge, phase shifted full bridge, half bridge, push-pull, two-switch forward, or active clamp forward converters. The project sample files listed in Project Sample Files section can also be loaded. Align all SR edges to OUTA, OUTB, OUTC, OUTD edges and adjust the primary-secondary propagation delay by programming the SR1 and SR2 delay. Program the adaptive dead time compensation function as shown in Figure 22 to improve the efficiency at light load condition. 11529-023 Additional PWM and SR evaluation options are: Figure 23. Filter Settings Window Warning While varying the compensator's parameters is possible when the part is running, the wrong combination of parameters can cause the system to become unstable. Rev. 0 | Page 14 of 40 Evaluation Board User Guide UG-566 Control Loop Configuration Transient Response for the Load Step To configure the control loop, use the following steps: A dynamic electronic load can be connected to the output of the evaluation board to evaluate the load transient response.

Using the information, the GUI software generates the Bode plots of the power stage and output voltage sense network separately. The switching frequency is determined in the PWM SR Settings window. Changing of the switching frequency changes the low frequency gain and the third pole position. The user can start to place the zeros and poles, and set the low frequency gain and high frequency gain of the digital compensator, based on the stability rules. The GUI then displays the full loop gain crossover frequency, the phase margin, the gain margin, and the phase crossover frequency. Using the loop analyzer, the user can verify the programmed control loop as shown in Figure 24. During the test on the control loop, the test signal from the loop analyzer can be easily injected in JP1 of the evaluation board. 11529-024 1. Figure 26. Transient Response with Load Steps: 50% to 75% to 50% UG-566 Evaluation Board User Guide INPUT VOLTAGE SETTINGS If the input voltage can be sensed by ADP1051 before the PSU is turned on (for example, the input voltage is sensed through the transformer windings of the auxiliary power circuit), the VIN on and VIN off limits can be programmed to control the input UVLO protection. Using the VIN Settings window in the Setup tab as shown in Figure 27, the user can program the VIN On limit and VIN Off limit. 11529-028 By proper selection of the input voltage feed forward options as shown in Figure 18, the input voltage feed forward can be evaluated in different ways. Figure 28 gives a result of the input voltage transient with the feed forward being disabled (Option C—Feed Forward always Disabled in Figure 18). While Figure 29 gives a result of the input voltage transient with the input voltage feed forward being enabled (Option A— Feed Forward always Activated in Figure 18). Figure 28.

It can also be conducted by applying a dynamic load to test the transient performance. Moreover, the drooping current share test can be conducted using two or more evaluation boards connected in parallel. The settings of drooping current sharing are shown in Figure 31. The droop resister is programmed as 20 mΩ and the IOUT update rate is programmed as 82 µs. Figure 34 gives drooping current sharing accuracy using two ADP1051-240-EVALZ evaluation boards connected in parallel. 11529-035 20 PSU OUTPUT CURRENT (A) 16 Figure 35.

Droop Current Sharing Accuracy Output Overvoltage Protection This test can be conducted in a number of ways. The simplest way is to set the output voltage to a value higher than the VOUT OV fault limit shown in Figure 30. Alternatively, shorting of the VS+ pin to AGND in the ADP1051 daughter card can cause a fast output overvoltage condition. The responses of the fault conditions can be programmed in the Flags and Fault Response Configurations section (see Figure 48). Figure 35 shows the waveforms when the response to an output overvoltage condition occurred. The ADP1051 also supports the conditional overvoltage protection. The settings of conditional output overvoltage protection are shown in Figure 31. Figure 36 shows a result of conditional overvoltage protection when the outputs of two evaluation boards are connected to a common bus. Figure 36. Conditional Overvoltage Protection with Two Evaluation Boards Connected to a Common Bus Output Undervoltage Protection This test can be done in a number of ways. The simplest way is to set the output voltage to a value lower than the VOUT UV fault limit value shown in Figure 30. Even a shorted load or an internal short (such as shorting of the synchronous rectifiers) can cause an output undervoltage condition. The response of the fault condition can be programmed in the Flags and Fault Response Configurations section. Rev. 0 | Page 18 of 40 Evaluation Board User Guide UG-566 OUTPUT CURRENT SETTING The input current settings are accessed using the CS1 and CS3 Settings window as shown in Figure 37. This window is used to program the cycle-by-cycle current limiting, the input overcurrent fast fault protection, the CS3 overcurrent protection and the volt-second balance control. The output current settings window is accessed using the IOUT Settings window. This window features the output overcurrent fault limit, the thresholds for the light load threshold and the deep light load, the responses for the light load threshold and the deep light load, the constant current mode, and the SR reverse current control. 11529-038 11529-037 INPUT CURRENT SETTINGS Figure 37.

Input Overcurrent Fast Fault Protection 11529-039 This test can be conducted by shorting the load. Using the setting window shown in Figure 37, the user can specify the IIN OC fast fault limit value by 2, 8, 16, 64, 128, 256, 512, or 1024. The fault response can be configured in the Flags and Fault Response Configurations section. Figure 39. IOUT Settings Window 2 Rev. 0 | Page 19 of 40 UG-566 Evaluation Board User Guide Output Overcurrent Protection Figure 42 and Figure 43 show results that the constant current mode happens during a soft start when two evaluation boards are connected in parallel. The load is a CR load. This test can be conducted by applying a load current larger than the value programmed by the IOUT OC fault limit (shown in Figure 38). The fault response is programmed in the Fault Response window shown in Figure 48. 11529-041 Figure 40 gives an experimental result by setting the IOUT OC fault limit at 25 A and enabling soft start after every 250 ms. 11529-040 Figure 41. Constant Current Control During Startup; Constant Current Threshold is 10 A Figure 40. IOUT OC Response Experimental Result Constant Current Mode 11529-042 Prior to the constant current mode test, the user needs to configure the constant current mode settings in Figure 39, including the output voltage change rates and the output current averaging speeds. This test can be conducted in multiple ways: • • • • • • The constant current mode happens during a soft start at a CR load. The test is done on a standalone evaluation board. The constant current mode happens during a soft start at a CV load. The test is done on a standalone evaluation board. The constant current mode happens during a CR load transient. The test is done on a standalone evaluation board. The constant current mode happens during a CV load transient. The test is done on a standalone evaluation board. The constant current mode happens during a soft start when two or more evaluation board are connected in parallel. The load is a CR load.

Rev. 0 | Page 20 of 40 Evaluation Board User Guide UG-566 SR Reverse Current Protection Light Load Efficiency Optimization This test can be conducted by several ways: The ADP1051 can be programmed to optimize performance when the output current drops below a certain level. The light load mode threshold and deep light load mode threshold are programmed in a manner to reduce the losses and increase the efficiency. A hysteresis for the light load mode and the deep light load mode is provided on the thresholds to avoid the current oscillations. The thresholds for light load mode and deep light load mode can also be programmed in the IOUT window as shown in Figure 39. • • • At a no load condition, the VOUT voltage is adjusted from a higher voltage to a lower voltage with the fastest VOUT transition rate. Up to 10,000 µF capacitance is connected at output terminals. Switch the load current between full load and no load with the fastest current slew rate programmed by E-load. At a no load condition, use an air switch to short the input terminals. A capacitor with up to 10,000 µF capacitance can be connected at the output terminals. This is a typical input voltage dip test. Figure 44 shows a result where the output voltage is adjusted from a higher voltage to a lower voltage. Figure 45 shows a result that the input is shorted by an air switch. When operating in the light load mode or deep light load mode, the mode flag is set in the Monitor tab. In combination with the pulse skipping mode, the standby power consumption can be reduced. The user can try the test items as follows: • • • 11529-044 • Try different thresholds for light load mode and deep light load mode to test the efficiency improvement. Try different averaging speed for light load mode and deep light load mode to test the transient response by applying a dynamic load. Program the threshold for the pulse skipping mode to test the efficiency improvement during standby mode. Select the PWM channels to be disabled during the deep light load mode as shown in Figure 46. 11529-046 Figure 44. SR Reverse Current Protection During Output Voltage Adjustment 11529-045 Figure 46.

The user can program the OT fault limit and OT warning limit through the Temperature Settings window shown in Figure 47. The OT hysteresis is the value difference of OT fault limit and OT warning limit. Figure 48. Fault Response Window TRIMMING 11529-047 This test allows the entire power supply to be calibrated and trimmed digitally through the ADP1051 in the production environment. Figure 47. Temperature Settings Window FLAGS AND FAULT RESPONSE CONFIGURATIONS The fault responses can be programmed in the Fault Response window of the Setup tab as shown in Figure 48. The state of faults can be monitored in the Monitor tab as shown in Figure 11. There are two groups of fault responses: • • All the ADP1051 parts are factory calibrated. The trimming is not needed if the voltage and current sense resistors have a high enough accuracy (see the ADP1051 data sheet for details). However, the ADP1051 can be retrimmed by the user to compensate for the errors introduced by external components. All the trimming can be done in the Trim Settings window of the Setup tab as shown in Figure 49. PMBus faults responses, including IOUT OC, VOUT OV, VOUT UV, and OT. Manufacturer specific fault responses, including IIN OC FAST, CS3 OC, VIN UV, Flagin, SR RC, VDD OV. There is a global reenabling timing for all manufacturer specific fault responses. When there is a fault causing the power supply to be shut down and a soft start is required if the PWM outputs are reenabled, the first fault ID information is shown in the Monitor tab. The first flag ID register gives the user more information for fault diagnosis than a simple flag. Rev. 0 | Page 22 of 40 11529-049 The user can test this section by applying a fault condition. By changing the settings of the debounce timing, delay timings, responses and reenable timings, the user can see different protection performance. Figure 49. Trimming Window Evaluation Board User Guide UG-566 SYNCHRONIZATION POWER GOOD SIGNAL Synchronization as a Master Device This test can be conducted by applying a fault condition, which is used to trigger a PGOOD flag and pull down the PG/ALT pin. The user can follow the PGOOD Settings window shown in Figure 51 to program which fault signal asserts the PGOOD flag. In the case of a fault to trigger the PGOOD flag, the D17 LED is turned off indicating that the power supply is not good. Figure 52 shows that a VOUT_UV_FAULT flag triggers the PGOOD output (PG/ALT pin). This test can be done by specifying OUTC or OUTD as a SYNO signal using the Sync Settings window of the Setup tab as shown in Figure 50. The SYNO signal should be stable to constantly represent the internal switching frequency once the ADP1051 VDD voltage is applied. Jumper JP11 to Jumper JP13 can be used to configure OUTC or OUTD connected to SYNO. The user can test the SYNO clock through the test point TP35 or the SYNC pin in the JP17 and JP18 connectors. Synchronization as a Slave Device This test can be done by applying an external clock signal in the TP25 test point. Alternatively, the external clock signal (such as SYNO signal in the master device) can be applied in the SYNC pin of the J17 or J18 connector. The settings can be programmed in the Sync Settings window (see Figure 50). To view the synchronization performance, try the following items: 11529-051 Figure 51. PGOOD Configurations 11529-052 • • Enable and disable synchronization. Set different delays to see the phase shift between master device and slave device. Program the different phase capture range. If the external clock signal is generated by a signal generator, the user can try to program the clock signal in sweep mode or burst mode to see the synchronization locking or unlocking. Figure 52.

Synchronization Configurations Rev. 0 | Page 23 of 40 UG-566 Evaluation Board User Guide PHASE SHIFTED FULL BRIDGE OPERATION All the test items are similar to the general full bridge operation. The only difference is the SR reverse current protection. In case of SR reverse current, configure the synchronous rectifier to be disabled. The user can load the phase shifted full bridge project sample file, ADP1051-240-EVALZ-FSFB-SAMPLE.51s, to do the evaluation. 11529-054 The PWM settings for phase shifted full bridge operation is highly flexible. Either the QA/QB leg (controlled by OUTA/ OUTB PWM outputs) or the QC/QD leg (controlled by OUTC/ OUTD PWM outputs) can be configured to run in modulation mode. Figure 53 provides a PWM setting example of the QA/QB leg in positive modulation mode. In this case, the QA/QB leg is the leading leg and the QC/QD leg is the lagging leg. Figure 54. PWM Waveforms under PSFB Operation DIRECT PARALLELING The direct paralleling function is that multiple power supplies output rails are connected directly to a common bus without the existing of OR’ing devices. To overcome the challenges for direct paralleling, implement the following series of features: • • • 11529-053 • • • Figure 53. Phase Shifted Full Bridge PWM Setting Window Prebias start up. Current sharing. Use drooping current sharing or active current sharing (through the current share daughter card). Synchronous rectifiers reverse current protection to avoid sinking current in a power supply. Constant current control and hot-switching control. Synchronization to reduce the output voltage ripple. Conditional overvoltage protection for redundant control. All the previous features are implemented in the ADP1051-240EVALZ evaluation board. Rev. 0 | Page 24 of 40 Evaluation Board User Guide UG-566 All the features listed in this section can be conducted in this direct paralleling system. 11529-056 Figure 56 shows the setup of two ADP1051-240-EVALZ evaluation boards connected in parallel for direct paralleling test. Each board can be controlled by SW1 on each board (R73 should be removed). Alternatively, the SW1 on Board B can be configured to control both Board A and Board B. In this case, remove the JP4 jumper on Board A. For synchronization, if the ADP1051 in Board A is assigned as a slave device, then assign the ADP1051 in Board B as a master device. In this case, the SW2 in Board A should be turned to the slave position and the SW3 in Board B should be turned to the master position. Figure 55.
