The RT7885V is a USB Power Delivery (USB PD) controller adopting Buck-Boost PWM control scheme and highly integrating functions specially for USB power bank applications, with that this controller is designed to operate in peak current mode with programmable current limit and switching frequency.

The RT7885V embeds an ARM CortexTM-M0 MCU so as to facilitate various functions of communication protocol, protections and customized requirements. Moreover, this RT7885V has built-in charge pumps for driving low-cost NMOS to control the power path. Therefore this IC provides the best USB PD solution for a power bank application with the lowest count of external components.
