Connect the positive (+) ammeter terminal to the evaluation board for Buck 1, VOUT1, the negative (−) ammeter terminal to the positive (+) load terminal, and the negative (−) load terminal to the evaluation board at PGND. POWERING UP THE EVALUATION BOARD The ADP5034 TSSOP evaluation board is supplied fully assembled and tested. 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 Pin Channel 1 2 3 4 Enable Pin JEN1 JEN2 JEN3 JEN4 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. Jumper JMODE (MODE) The Jumper JMODE 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 JMODE to the top pin header to pull the MODE pin high to VIN1. To allow Buck 1 and Buck 2 to operate in automatic PWM/PSM operation, shunt the center contact of JMODE to the bottom pin header to pull the MODE pin low to PGND. Connect the input voltage measuring voltmeter positive terminal (+) to the evaluation board at VIN1, and input voltage measuring voltmeter negative (−) terminal to the evaluation board at PGND. Connect the output voltage measuring voltmeter positive (+) terminal to the evaluation board at VOUT1 for measuring the output voltage of Buck 1, and the output voltage measuring voltmeter negative (−) terminal to the evaluation board at GND. Input Power Source Turning On the Evaluation Board If the input power source includes a current meter, use that meter to monitor the input current. VIN1 directly connects to AVIN and VIN2. Attach a header on JVIN3 to connect the supply of LDO1 to VIN1, and attach a header on JVIN4 to connect the supply of LDO2 to VIN1. Connect the positive terminal of the power source to VIN1 on the evaluation board and the negative terminal of the power source to PGND. When the power source and load are connected to the evaluation board, the board can be powered for operation. Ensure that: 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 PGND on the evaluation board, and the negative lead (−) of the ammeter to VIN1 on the board. Be aware that the current meters add resistance to the input source, and this voltage reduces with high output currents. The desired channel is enabled and monitors the output voltage. 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 output, VOUT1, and the negative (−) load connection to PGND. The power source voltage for the Bucks (VIN1, VIN2) is from 2.3 V to 5.5 V. The power source voltage for the LDOs (VIN3, VIN4) is from VOUTLDO + 0.5 V or 1.7 V (whichever is greater) to 5.5 V. Note that VIN3 and VIN4 should be the same or below the voltage supplied on VIN1 and VIN2. 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.

BUCK1 External Output Voltage Setting Setting the Output Voltage of the LDOs Each LDO output voltage is set through external resistor dividers as well as shown in Figure 3 for LDO1. 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 leave RBOT unpopulated. Refer to Table 2 for the corresponding 0 Ω resistor placements on RTOP per channel. VIN3 VOUT3 VOUT3 LDO1 FB3 RTOP C7 1µF To observe the switching waveform with an oscilloscope, place the oscilloscope probe tip at the end of the inductor with the probe ground at GND. Set the oscilloscope to dc, 2 V/division, and 200 ns/division time base. 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 5 and Figure 6. 10895-003 RBOT Figure 4.

Typical Waveforms, VOUT1 = 3.3 V, IOUT1 = 30 mA, PSM Mode Measuring Output Voltage Ripple of the Buck Regulator T 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 also 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 on Figure 4.

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.

Buck Line Regulation Rev. 0 | Page 5 of 16 UG-439 Evaluation Board User Guide Measuring Line Regulation of LDO 3.3160 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. 3.3155 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 10 shows the typical line regulation performance of the LDO with a fixed 3.3 V output. 3.3140 3.3150 VIN = 5.5V VOUT (V) 3.3145 VIN = 4.2V 3.3135 3.3130 3.3125 VIN = 3.6V 3.3120 0 ILOAD = 1mA 200 250 300 Measuring Dropout Voltage of LDO 3.315 VOUT (V) 150 Figure 11.

LDO Line Regulation Measuring Load Regulation of LDO 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 11 shows the load regulation performance of the LDO with a 3.3 V output for different input voltages. Dropout voltage is defined as the input-to-output voltage differential when the input voltage is set to the nominal output voltage. 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 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. Rev. 0 | Page 6 of 16 Evaluation Board User Guide UG-439 Cascading an LDO from the Buck Regulator by shunting the jumper JV3V1. Subsequently, VIN4, which is the supply of LDO2 can also be connected to VOUT2 through jumper JV4V2. 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. For certain applications such as analog circuit supplies, the LDOs are preferred because of its better noise performance than the bucks. Where not all the buck outputs are being used, the input supply of the LDOs can be taken from these outputs. An example demo board connection is shown in Figure 12 wherein VOUT1 is tied to VIN3, which is the supply of LDO1, VOLTAGE SOURCE VOLTMETER 1.99711 – + – 10895-012 + Figure 12. Cascading LDO from Buck Rev. 0 | Page 7 of 16 UG-439 Evaluation Board User Guide MEASURING OUTPUT VOLTAGE Figure 13 shows how the evaluation board can be connected to a voltage source and a voltmeter for basic output voltage accuracy measurements. It shows a voltage source connected to VIN1 and a voltmeter connected to VOUT1S, which is the output voltage sense terminal of Buck 1. JEN1 is connected to VIN1 via a shunt which enables Buck 1; JEN2, JEN3, and JEN4 are connected to ground, disabling the other channels. When measuring the voltages on VOUT2, VOUT3, and VOUT4, make sure that the respective channels are enabled, and the voltmeters are connected to the respective outputs. 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.
