The RT6190GQW from Richtek is a 4-switch Bi-directional Buck-Boost Controller that converts an input voltage of 4.5- 36 V to an output voltage of 3-36 V. It has been designed for USB power delivery (USB PD) and implements peak current mode control mechanism with the programmable constant voltage (CV) and constant current (CC) output to support USB-PD 3.0 SPR and 3.1 EPR modes. This JEDEC-compliant DC-DC controller offers bi-directional power delivery enabling forward and reverse operation and has a programmable switching frequency of 250 kHz to 1 MHz. It consists of built-in charge pumps for driving external low-cost N-Channel MOSFETs to control the power path as well as an I2C compatible interface to support many programmable functions including CV/CC output, switching frequency, and cable voltage drop compensation.

This RoHS-compliant DC-DC converter offers input under-voltage lockout (ULVO) protection, over/under voltage protection, cycle-by-cycle current limit, short protection, and over-temperature protection to prevent over current, over-voltage, over-heating, and short circuit-related damages. It is available in a surface-mount package that measures 5 x 5 mm and is ideal for monitors, USB power delivery, and power bank applications.
