ST launches reference design for USB Type-C power adapters STMicroelectronics has revealed a USB Type-C Power Delivery 3.0 reference design with Programmable Power Supply (PPS) support to accelerate the design of power adapters up to 27W with zero-power operation when no cable is connected.
USB PPS helps to save power, and reduce device-charging times and heat dissipation, contributing also to cut bill-of-materials costs on the device side.
The STEVAL-USBPD27S reference design combines the STM32G071 microcontroller (MCU), which integrates a complete USB Type-C Power Delivery controller on-chip, with the STCH03 state-of-the-art PWM controller and TCPP01-M12 USB Type-C protection IC.
