RT6190 Overview
The RT6190 is a 4-switch bidirectional 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 RT6190 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 3.1 EPR mode.
