The RT8130B is a high efficiency single phase synchronous Buck DC/DC controller with 5V/12V supply voltage. <p align="justify">The RT8130B has embedded MOSFET gate driver with high driving capability, supporting driving voltage up to 12V for high output current application. This device uses lossless low-side MOSFET R<sub>DS(ON)</sub> 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 RT8130B 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 RT8130B is available in the WDFN-10L 3x3 package.</p>
