basicInfoImageSwitcher
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. With an I<sup>2</sup>C compatible interface, the RT6179 supports many programmable functions including CV/CC output, switching frequency, and cable voltage drop compensation. Moreover, the RT6179 integrates fully protection such as input UVLO, over/undervoltage protection, cycle-by-cycle current limit, short protection, and over-temperature protection. The RT6179 is available in a WQFN-40L 5x5 package.
