Additional preview pages of the RT8129B datasheet.

The RT8129B is a high efficiency single phase synchronous buck controller with 5V/12V supply voltage.

include power good indication, enable/disable control and internal soft-start function. The RT8129B also provide protection functions including Over-Voltage Protection (OVP), Under-Voltage Protection (UVP), current limit and thermal shutdown. This device uses lossless low-side MOSFET RDS(ON) current sense technique for current limit with adjustable threshold set by connecting a resistor between the LGATE/OCSET and GND. With above functions, the RT8129B provides customers a cost-effective solutio.
