3.1 Buck Mode Power-Up and Power-Down Sequence

1. Refer to Table 2 through Table 5 for proper jumper settings
2. Turn on the HV-PS power supply.
3. Turn on the LV-PS power supply and LV-E-Load.
4. Apply a voltage > 2.5 V and < 6 V at J17-pin 5 (Master Enable).
5. Apply an analog voltage gradually rising from 0V to 1.5V at J17-pin 11 or J18-pin 11 (ISETA), or a PWM signal of duty ratio of 0 to 48% at J17-pin 13 or J18-pin 13.
6. Perform the test.
7. After the tests are done, turn off the ISETA or ISETD signal, remove the voltage at J17-pin 5, and turn off the E-Load, LV-PS and HV-PS.
