RT8129B 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...
