Overview
RT8129B High Efficiency Single Synchronous Buck PWM Controller General Description 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 condition.
At light load condition, it automatically operates in the diode emulation mode to reduce switching frequency and improve conversion efficiency.
Other features include power good indication, enable/disable control and internal soft-start function.
The RT8129B also provide protection functions including Over-V...
