RT6179 Overview
The RT6179 is a 4-switch Buck-Boost controller designed for USB power delivery (USB PD). It operates with wide input voltage range from 4.5V to 36V, and the output voltage can be programmable between 3V and 36V. The RT6179 implements peak current mode control mechanism with the programmable constant voltage (CV) and constant current (CC) output to support USB-PD 3.0 SPR mode and 28V of 3.1 EPR mode.
