It is a full bridge topology. Figure 1 gives a block diagram of the main components on the board. The primary side consists of the input terminals, full bridge switches and the main transformer. The gate signal for the switches comes from the ADP1043A, through the iCoupler and the drivers. This controls the switching of the Rev. Prelim A, Oct 2009 | Page 4 of 27 Reference Design PRD 1153 transformer. There is also a current sense transformer, to transmit the primary side current information to the ADP1043A on the secondary side. The secondary side power stage consists of the synchronous rectifiers, output LC tank, sensing resistor. This provides 12V @ 25A at the output. The ADP1043A is also located on the secondary side. The ADP1043A provides the feedback signal that is used to regulate the voltage, limit the current, and allow current sharing and shutdown to be implemented. Low side current sensing is used. The ADP1043A also controls the share bus, which allows multiple power supplies to perform load sharing. The ADP1043A feedback to the primary side, through the iCoupler, consists of the voltage sense, current sense and share bus information. There is a 4 pins connector for I2C communication. This allows the PC software to communicate with the eval board (and with other eval boards through extra 4 pin connectors) through the USB port of the PC. The user can readily change register settings on the ADP1043A this way, and also monitor the status registers. The eval board is designed with a 0.5 mOhm RSENSE resistor. The power supply is designed to support a maximum continuous output of 25 A. The current sense has been calibrated such that 25 A corresponds to 100% of output current rating. A variable load is required to perform a thorough evaluation. The output voltage is available between P4 and P9, and this is also where the load should be connected. The power supply will be in Continuous Conduction Mode. If the synchronous rectifiers are enabled, the power supply will remain in CCM mode over the full load range. The output voltage ripple is approx 100mVp-p. Figure 2. Pin connection diagram (Top view) CONNECTORS The connections to the eval board are shown in Table 1. Rev.

Install the ADP1043A software. Refer to the Quick Start Guide that comes on the CD (If already installed, skip to the next step). 2. Connect the evaluation board to the USB port on the computer, using the “USB to I2C interface” dongle. If the dongle driver was not previously installed, run the software from the Start Menu under “Programs/Analog Devices/ADP1043A”. 3. The software should report that the ADP1043A has been located on the board. Click “Finish” to proceed to the Main Software Interface Window. Figure 5. Getting Started 4. Click on the icon: select the “25A QB300W board.43b file”. This file contains all the board information including values of shunt and voltage dividers. Rev. Prelim A, Oct 2009 | Page 8 of 27 Reference Design PRD 1153 Figure 6. Load Board Setting 5. The ADP1043A is pre-programmed and calibrated, so there is no programming necessary. 6. Connect an electronic load at the output. 7. For the input voltage source, a DC power supply can be used. The input voltage range is 0 to 100 VDC (48VDC is recommended). This input voltage is the signal which will be regulated to provide a 12V/25A supply at the output. Set the voltage to 48VDC 8. The eval board should now up and running, and ready to evaluate. The output should be 12 VDC. BOARD EVALUATION The ADP1043A is optimized for improving the power supply design and evaluation process. The goal of this eval kit is to allow the user to get an insight into the flexibility offered by the extensive programming options offered by the ADP1043A. The ADP1043A performs many monitoring and housekeeping functions in the power supply. The eval board allows the user to simulate various events that could affect the ADP1043A in a working system. The user can monitor how the ADP1043A handles this event in many ways. One way is to use an oscilloscope and/or multimeter, and probe the eval board, to see various conditions in the system. Many test points have been provided for this function. The user can also use the software to monitor the conditions of the ADP1043A, and how it has reacted to the event. The following section gives some experiments that the user might typically evaluate. LINE AND LOAD VOLTAGE REGULATION Vary the input voltage from 38 VDC to 72VDC. The output voltage remains 12V. Vary the load current from 0 to 25A. The output voltage remains 12V. Rev. Prelim A, Oct 2009 | Page 9 of 27 Reference Design PRD 1153 OUTPUT VOLTAGE SETTING The output voltage setting is programmable. Using the Voltage setting window in the software, adjust the output voltage (using the o/p trim menu). Monitor the actual output voltage of the power supply using the software or a multimeter, or looking at the output voltage reading on the electronic load. It should match the programmed value. This will be used to calibrate the power supply in the production environment. By doing this evaluation, the user can see how the ADP1043A can be trimmed digitally to adjust the output voltage. SOFT START Once the input voltage is applied it is possible to test the Soft Start of the ADP1043A. The settings are located in the General Settings Window. Please refer to the Software Reference Guide for a detailed explanation of all the controls (EVAL-ADP1043A-GUI-RG). Figure 7. General Settings Window Soft Start is enabled and set to 40ms. You can experiment with different times. Rev. Prelim A, Oct 2009 | Page 10 of 27 Reference Design Figure 8. PRD 1153 SoftStart (Yellow VOUT – Green IOUT) DIGITAL FILTER – TRANSIENT ANALYSIS The digital filter can be changed using the software. The effect on transient analysis can be evaluated this way. Connect a switching electronic load to the output of the eval board. The load should be set to switch between 25%-50% or 50%-75%, changing every 10msecs. Set up an oscilloscope to capture the transient waveform of the power supply output. Use a differential probe on the scope, connecting it to the eval board output. Turn on the load, and note the waveform response. The scope should be ac-coupled, 200mV/division, with a timebase of 1msecs/division. Also connect a current probe, set up for 5A/div. Set the trigger at 9A on the current probe signal. Rev. Prelim A, Oct 2009 | Page 11 of 27 Reference Design Figure 9. PRD 1153 Transient Response – 75% to 50% load step Rev. Prelim A, Oct 2009 | Page 12 of 27 Reference Design Figure 10. PRD 1153 Transient Response – 50% to 75% load step Now, vary the digital filter using the software. Click on “Filter Settings” the window shows the filter settings for Normal mode. Click on the curve to move position of poles, zeroes and gains. Rev. Prelim A, Oct 2009 | Page 13 of 27 Reference Design PRD 1153 Figure 11. Digital Filter window The transient response will change. This evaluation shows the user how the digital filter can easily be programmed to optimize the transient response of the power supply. PWM – SWITCHING FREQUENCY The converter switching frequency is programmable. In the “PWM & SR Settings” change the switching frequency. The minimum and maximum modulation limits can also be modified. Rev. Prelim A, Oct 2009 | Page 14 of 27 Reference Design PRD 1153 Figure 12. PWM Timing Window NOTE: It is recommended to evaluate this feature with the power supply turned off. This prevents the chance of damaging the power supply by introducing shoot-through. LIGHT LOAD OPTIMIZATION The ADP1043A can be programmed to optimize performance when a output current drops below a certain level. The threshold for light load mode can be programmed in the “CS2 Settings” window. Once the current will drop below this level the sync rectifiers (SR1 and SR2) will be disabled and the other five PWM can also be disabled by marking the corresponding checkboxes. The “Light Load Mode Settings” in “Filter Settings” will be used. The response time for the ADP1043A to switch from one mode to another is between 10 and 20ms. The light load mode can be disabled by selecting a Light Load Current Threshold of 0%. Rev. Prelim A, Oct 2009 | Page 15 of 27 Reference Design PRD 1153 Figure 13. Light Load Mode Control Window PRIMARY SIDE CURRENT SENSE AND SECONDARY SIDE CURRENT SENSE Current sensing is available for both the primary side current and the secondary side current. Primary side current sensing is performed using the current transformer, T1. Secondary side current sensing uses a low-side sense resistor (R21, R29, R98 and R99). Open the Flags and Readings window in the software. Adjust the load current from 0A to 25A. The input current and output current values will change in the software, matching the changes being made at the load. VOLT-SECOND BALANCE The ADP1043A has an integrated Volt-Second Balance circuit. This means that there is no need for a dc blocking capacitor in the main power path on the primary side. Set the load current to 1A. Place a scope probe on the CS1 pin of the ADP1043A. Setup the scope to 200mV/div, 5usecs/div. A typical CT waveform should be on the scope. Using the software, toggle Reg 52h, Bit 1. To exaggerate an imbalance, use the PWM window in the software to intentionally place a timing mismatch. For example, move T3 from 2.5usecs to 2.51usecs. FLAGS, AND FAULT CONFIGURATIONS Open the Flags and Readings window in the software. The window will show all of the fault flags. If a flag is set, then there is a red box next to the flag. If the flag is ok, then there is a green box next to the flag. Rev. Prelim A, Oct 2009 | Page 16 of 27 Reference Design PRD 1153 Figure 14. Flags and Readings Set the load current to 0.3A. The CS2 OCP flag should be green. Note that the SR flag and the Light load mode flags are red to indicate that the ADP1043A is in this state. Rev. Prelim A, Oct 2009 | Page 17 of 27 Reference Design PRD 1153 Figure 15. Flags in Light load mode Now change the load to 28 A. The CS2 OCP flag should now have turned red, because the CS2 OCP threshold has been reached. The board wills ender in hiccup mode and try and restart. Set the load back to 2A, and the flag turns green again. This shows how the user can easily monitor the health of the power supply by monitoring the status of the various flags. FLAG & FAULT RESPONSE CONFIGURATION: The ADP1043A is programmed to respond to the various fault conditions in the “Flag Settings” window. Rev. Prelim A, Oct 2009 | Page 18 of 27 Reference Design PRD 1153 Figure 16. Fault Configurations You can change the resolve issue to “Remain Disabled”. If the overcurrent is applied again the ADP1043A will shut down and remain off until PSON is cycled. This evaluation shows how it is quite easy to configure the response to a fault condition. Change the load back to 2A, then toggle the PS_ON switch to restart the power supply. Rev. Prelim A, Oct 2009 | Page 19 of 27 Reference Design PRD 1153 APPENDIX Figure 17.
