RT7202K
Highly Integrated USB PD Type-C Controller for SMPS
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
RT7202KD for a sink design, it has I
2
C interface and two
GPIOs for flexible use and could be easily controlled by
other MCU which plays a master role.
