Operating Sequence
(The preparation for power up)
1.
Confirm if both JP_VIOSEL and JP_STP are shorted by a jumper pin. The EVK cannot work correctly if there are no jumper
pins on these terminals. It is highly recommended to be checked (These jumpers are present by default.).
2.
Short EN and ADCIN on JP_TOP if the Over Temperature Protection with the external PTC thermistor is in use. If not in use,
short ADCIN and SGND.
3.
Set SW_VMAX, SW_VMIN and SW_PMIN according to required PD contract. Please refer to Figure 9 for further information.
4.
When connecting the existing system board for evaluation, connect the EVK into the existing system board before power
up as shown in Figure 6.
