Before applying power to the evaluation board, follow the procedures in this section. Enable Each channel has its own enable pin, which must be pulled high to enable that channel (see Table 1). Table 1. Channels of the Enable Pins Channel 1 2 3 4 Enable Pin ADP5034/ADP5037 JP4 JP5 JP6 JP7 ADP5023/ADP5024 JP4 JP5 JP6 N/A Jumper J3 (MODE) The Jumper JP3 as shown in Figure 1 is used to connect the MODE pin of the device to either ground or VIN1. To force Buck 1 and Buck 2 into forced PWM operation, shunt the center contact of Jumper JP3 (MODE) to the left pin header to pull the MODE pin high to J1 (VIN1). To allow Buck 1 and Buck 2 to operate in automatic PWM/PSM operation, shunt the center contact of JP3 (MODE) to the right pin header to pull the MODE pin low to J12 (GND1). Input Power Source If the input power source includes a current meter, use that meter to monitor the input current. Connect J1 (VIN1) to J2 (VIN2) with a short wire. Connect the positive terminal of the power source to J1 (VIN1) on the evaluation board and the negative terminal of the power source to J12 (GND). If the power source does not include a current meter, connect a current meter in series with the input source voltage. Connect the positive lead (+) of the power source to the ammeter positive (+) connection, the negative lead (−) of the power source to J12 (GND) on the evaluation board, and the negative lead (−) of the ammeter to J1 (VIN1) on the board. Be aware that the current meters add resistance to the input source, and this voltage reduces with high output currents. positive (+) load terminal, and the negative (−) load terminal to the evaluation board at J8 (GND). Input and Output Voltmeters Measure the input and output voltages with voltmeters. Make sure that the voltmeters are connected to the appropriate evaluation board terminals and not to the load or power sources themselves. If the voltmeters are not connected directly to the evaluation board, the measured voltages will be incorrect due to the voltage drop across the leads and/or connections between the evaluation board, the power source, and/or the load. Connect the input voltage measuring voltmeter positive terminal (+) to the evaluation board at J1 (VIN1), and input voltage measuring voltmeter negative (−) terminal to the evaluation board at J12 (GND1). Connect the output voltage measuring voltmeter positive (+) terminal to the evaluation board at J5 (VOUT1) for measuring the output voltage of Buck 1, and the output voltage measuring voltmeter negative (−) terminal to the evaluation board at J8 (PGND). Turning On the Evaluation Board When the power source and load are connected to the evaluation board, the board can be powered for operation. Ensure that: The power source voltage for the Bucks (VIN1, VIN2) is >2.3 V to <5.5 V. The power source voltage for the LDOs (VIN3, VIN4) is from VOUT LDO + 0.5 V or 1.7 V (whichever is greater) to 5.5 V. The desired channel is enabled and monitors the output voltage. If the load is not enabled, enable the load; check that it is drawing the proper current and that the output voltage maintains voltage regulation. Setting the Output Voltage of the Bucks The buck output voltage is set through external resistor dividers, shown in Figure 2 for Buck 1. The output voltage can optionally be factory programmed to default values as indicated in the data sheet. In this event, R1 and R2 are not needed, and FB1 can be left unconnected. In all cases, VOUT1 must be connected to the output capacitor. FB1 is 0.5 V. Output Load Connect an electronic load or resistor to set the load current. If the load includes an ammeter, or if the current is not measured, connect the load directly to the evaluation board, with the positive (+) load connected to one of the channels. For example, connect Buck 1, J5 (VOUT1) and the negative (−) load connection to J8 (GND). If an ammeter is used, connect it in series with the load. Connect the positive (+) ammeter terminal to the evaluation board for Buck 1, J5 (VOUT1), the negative (−) ammeter terminal to the Rev.

The output voltage can optionally be factory programmed to default values as indicated in the data sheet. In this event, FB3 must be connected to the top of the capacitor on VOUT3 by placing a 0 Ω resistor on RTOP, and leaving RBOT unpopulated. Refer to Table 2 for the corresponding 0 Ω resistor placements on RTOP per channel. VOUT3 VIN3 LDO1 FB3 RTOP VOUT3 C7 1µF 09808-003 VOUT3 = VFB3 09808-001 RBOT RTOP +1 RBOT Figure 4.

LDO1 External Output Voltage Setting MEASURING EVALUATION BOARD PERFORMANCE External Resistor Divider Setting for Bucks and LDOs The ADP5023/ADP5024/ADP5034/ADP5037 demo boards are supplied with fixed resistors with values chosen for a target output voltage. Varying the resistor values of the resistor divider networks varies the output voltage accordingly. Table 2. External Resistor Dividers (Fixed) Resistor Divider RTOP RBOT Buck 1 R1 R2 Buck 2 R7 R8 LDO1 R15 R16 LDO2 R11 R12 Aside from the fixed resistors shown in Table 2, the demo boards also have footprints for trimmer resistors as listed in Table 3. The trimmer resistors make for easier adjustments of the output voltage by turning the adjustment slots on top of the resistors as shown in Figure 4. Measuring Output Voltage Ripple of the Buck Regulator To observe the output voltage ripple of Buck 1, place an oscilloscope probe across the output capacitor (COUT_1) with the probe ground lead at the negative (−) capacitor terminal and the probe tip at the positive (+) capacitor terminal. Set the oscilloscope to ac, 10 mV/division, and 2 μs/division time base, with BW set to 20 MHz to avoid noise to interfere with the measurements. It is recommended to shorten the ground loop of the oscilloscope probe to minimize coupling. A good way of measuring the output voltage ripple is to solder a wire to the negative (−) capacitor terminal and wrap it around the barrel of the probe, while the tip directly connects to the positive (+) capacitor terminal as shown in Figure 5. 09808-005 Turning the adjustment slot clockwise increases the resistance and vice versa; adjust accordingly to get the desired output voltage. The footprints are designed for 3214W-1-204E parts, which are 200 kΩ trimmer resistors. The trimmers are for quick evaluation purposes and are not recommended for final application; this is because of the possible mechanical issues and complex impedance. Once the desired output voltage is found, replace the trimmers with fixed value resistors. Table 3.

Set the oscilloscope to dc, 2 V/division, and 200 ns/division time base. Test the load regulation by increasing the load at the output and looking at the change in output voltage. The input voltage must be held constant during this measurement. To minimize voltage drop, use short low resistance wires, especially for loads approaching maximum current. T 1.7985 1.7980 VIN = 5.5V 1.7975 VOUT (V) When the MODE pin is set to high, the buck regulators operate in forced PWM mode. When the MODE pin is set to low, the buck regulators operate in PWM mode when the load is above a predefined threshold. When the load current falls below a predefined threshold, the regulator operates in power save mode (PSM), improving the light load efficiency. Typical PWM and PSM switching waveforms are shown in Figure 6 and Figure 7. 1.7970 VIN = 3.6V 1.7965 VOUT 1.7960 1 1.7950 2 0 100 200 300 400 500 600 700 800 900 1000 1100 1200 ILOAD (mA) SW 09808-108 VIN = 2.3V 1.7955 ISW Figure 8.

Buck Efficiency, VIN = 3.6 V, VOUT = 1.8 V Measuring Inductor Current For load regulation measurements, the regulator output is monitored while the load is varied. For good load regulation, the output must change as little as possible with varying loads. The input voltage must be held constant during this measurement. The load current can be varied from 0 mA to 300 mA. Figure 12 shows the typical load regulation performance of the LDO with a 3.3 V output for different input voltages. Measure the inductor current by removing one end of the inductor from its pad and connecting a current loop in series. A current probe can be connected to this wire. 3.3160 Measuring Line Regulation of LDOs 3.3145 For line regulation measurements, the output of the regulator is monitored while its input is varied. For good line regulation, the output must change as little as possible with varying input levels. To ensure that the device is not in dropout mode during this measurement, VIN must be varied between VOUT nominal + 0.5 V (or 2.3 V, whichever is greater) and VIN maximum. For example, a fixed 3.3 V output needs VIN to be varied between 3.8 V and 5.5 V. This measurement can be repeated under different load conditions. Figure 11 shows the typical line regulation performance of the LDO with a fixed 3.3 V output. 3.3140 3.3155 VOUT (V) 3.3150 Rev.

One way to measure dropout voltage is to get the output voltage (VOUT nominal) with VIN initially set to VOUT nominal + 0.5 V; output load can be set to 100 μA. Then, force the input voltage equal to VOUT nominal, and measure the output voltage accordingly (VOUT dropout). Dropout voltage is then calculated as VOUT nominal − VOUT dropout. This applies only for output voltages greater than 1.7 V. Dropout voltage increases with larger loads. For more accurate measurements, a second voltmeter can be used to monitor the input voltage across the input capacitor. The input supply voltage may need to be adjusted to account for IR drops, especially if large load currents are used. Measuring Ground Current Consumption of LDO Ground current measurements can determine how much current the internal circuits of the regulator consume while the circuits UG-271 perform the regulation function. To be efficient, the regulator needs to consume as little current as possible. Typically, the regulator uses the maximum current when supplying its largest load level (300 mA). When the device is disabled, the ground current drops to less than 1 μA. Refer to Figure 14 for a detailed instruction on how to perform ground current measurements. Cascading an LDO from the Buck Regulator For certain applications such as analog circuit supplies, the LDOs are preferred over the bucks because of better noise performance. Where not all the buck outputs are being used, the input supply of the LDO can be taken from these outputs. An example demo board connection is shown in Figure 13 wherein VOUT1 is tied to VIN3, which is the supply of LDO1. In this configuration, the output voltage of the buck regulator should have enough headroom with the desired output voltage of the LDO to guarantee the LDO to operate within specifications.

Figure 14 shows how the evaluation board can be connected to a voltage source and a voltmeter for basic output voltage accuracy measurements. Figure 14 shows a voltage source connected to VIN1 and a voltmeter connected to VOUT1, which is the output of Buck 1. EN1 is connected to VIN1 via a shunt, which enables Buck 1, and EN2, EN3, EN4 are connected to ground, disabling the other channels. When measuring the voltages on VOUT2, VOUT3, and A resistor can be used as the load for the regulator. Ensure that the resistor has a power rating adequate to handle the power expected to be dissipated across it. An electronic load can also be used as an alternative. Ensure that the voltage source can supply enough current for the expected load levels. VOLTAGE SOURCE – VOLTMETER 1.99711 + – 09808-114 + Figure 14. Ground Current Measurement Rev.
