1. DC-DC converter recommend best solution. The following table can pass USB PD compliance test.

2. The RT8131B is a high efficiency single phase synchronous buck DC-DC controller. Please refer to the RT8131B

datasheet.

3. The RT8525D is a wide input operating voltage range step up controller. High voltage output and large output current

are feasible by using an external N-MOSFET. Please refer to the RT8525D datasheet.
