The RT8131B is a high efficiency single phase synchronous Buck DC-DC controller with 5V supply voltage.
The RT8131B has embedded MOSFET gate driver with high driving capability, supporting driving voltage up to 5V. This device uses lossless low-side MOSFET RDS(ON) current sense technique for over-current protection with adjustable threshold set by the LGATE pin (LGOCS). Other features include power good indication, enable/disable control and internal soft-start. The RT8131B also provides fault protection functions to protect the power stage output. With above functions, the IC provides customers a cost-effective solution for high efficiency power conversion. The RT8131B is available in the WDFN-10L 3x3 package.
