EVB_RT8130BGQW: 12V @ 7A, 2.5 ~ 21 Vin

Summary

The EVB_RT8130BGQW is a high efficiency single phase synchronous Buck DC/DC controller with 5V/12V supply voltage. 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 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 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.
