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/KJ/KT/KS for a sink design, it has I2C interface and two GPIOs for flexible use and could be easily controlled by other MCU which plays a master role.
The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 105°C.
