RT8129B Datasheet (Richtek) - High Efficiency Single Synchronous Buck PWM Controller

RT8129B, High Efficiency Single Synchronous Buck PWM Controller

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

The RT8129B integrates a Constant-On-Time (COT) PWM controller and a MOSFET drivers with internal bootstrap diodes, which is specifically designed to improve converter efficiency at light load condi

RT8129B Features

* 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
