RRW30120 USB PD 3.2 EPR Controller

The Renesas RRW30120 is a programmable USB PD controller with extended power range (EPR) support for power source applications. The device integrates a secondary-side regulation controller, interface protocol controller, and USB VBUS NFET driver into a single IC. The RRW30120 supports EPR up to a 48 V output voltage.

The RRW30120 has an internal MCU and hardware interface for the USB PD protocol. It allows rapid charging of any USB PD protocol-enabled sink devices such as mobile devices (MDs), notebook PCs (NB), monitors, and power tools. It resides on the secondary side of an AC/DC power supply and configures the adapter for multi-level voltage and current output.

RRW30120 measures the output voltage and load current in real time. The measurement results are sent to a digital compensator for closed-loop control of the power converter. The digital control signal generated by the compensator is converted to an analog signal and transferred to the primary-side controller via an optocoupler.

The RRW30120 is optimized to pair with the Renesas high-power-density QR and ZVS Flyback primary-side controller to achieve high efficiency, low no-load power consumption, accurate voltage/current control, and fast dynamic load response. The RRW30120 also includes the necessary hardware for multi-port power adapter design with minimal BOM cost.
