General Description

The RT7202K is a simple and yet flexible for multipurpose

of USB PD controller. By programming, it could operate

as a source or a sink.

When used as a source, it could be used in an off-line

AC-DC converter, as it integrates shun regulator, constant

voltage (CV) and constant current (CC) control loop with

programmable reference voltage to meet the specification

of Programmable Power Supply (PPS) specification. When

combined with external buck or buck boost controller, it

could constitute a DCDC converter, such as a car charger

, and could also meet the PPS specification. When used

as a sink, it is simple, low cost, yet flexible to use to

request required power from a source. If using the

GPIOs for flexible use and could be easily controlled by

other MCU which plays a master role.
