TPS16630-32EVM: Evaluation Module for TPS1663x

3.4

Test Procedure

NOTE:

CH1 and CH2 can be tested one by one with a single power supply and the load.

3.4.1

Preliminary Tests

1. Turn on the power supply and set the output voltage and the current limit according to

Table 6

.

2. Turn on the load and set the load resistance to 24-

±1

.

3. Disable the power supply, load and hook up the TPS16630-32EVM assembly as shown in

Figure 1

4. Make sure the default evaluation board jumper settings are as shown in

5. Enable the power supply and the load.

6. Connect the negative probe of the DMM to test point TP5 or TP14, the positive probe to the respective

test points and verify that the voltages shown in

Table 8

are obtained.

7. Press the CH1/CH2 shutdown switch S1/S2 and verify the CH1/CH2 output voltage VOUT1/VOUT2

drops to zero. Release the S1/S2 switch and verify the output voltage resumes to nominal 24-V ±1 V.

8. Disable the power supply and the load.

3.4.2

UVLO, OVP Tests

Follow the instructions to verify undervoltage and overvoltage levels of the device:

1. Set the load resistance to 24-

±1

and the power supply voltage to 24 V. Enable the power supply

and the load.

2. Increase the CH1 input voltage (VIN1) and monitor the output voltage (VOUT1). Verify that VOUT1

increases as VN1 increases and drops to zero when VIN1 exceeds 33-V ±1 V (CH1 OVP limit).

3. Reduce the CH1 input voltage and verify that the output turns on at 31-V ±1 V.

4. Further reduce the CH1 input voltage and verify that VOUT1 reduces as VN1 reduces and drops to

zero when VIN1 falls below 18-V ±1 V (CH1 UVLO limit).

5. Increase the CH2 input voltage (VIN2) and monitor the output voltage (VOUT2). Verify that VOUT2

increases as VN2 increases and clamps to 35 V when VIN2 exceeds 35-V ±1 V (CH2 OV Clamp limit).
