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. It also has built-in charge pumps for driving external low-cost N-MOSFETs to control the power path. With an I2C compatible interface, the RT6190 supports many programmable functions including CV/CC output, switching frequency, and cable voltage drop compensation. Moreover, the RT6190 integrates fully protection such as input UVLO, over/under voltage protection, cycle-by-cycle current limit, short protection, and over-temperature protection. The RT6190 is available in a WQFN-40L 5x5 package.
