RT9202 - Richtek

RT9202 Single Synchronous Buck PWM DC-DC Controller

The RT9202 is a single power supply PWM DC-DC converter controller designed to drive N-channel MOSFET in a synchronous buck topology. The IC integrates the control, output adjustment, monitoring and protection functions in a small 8-pin package. The RT9202 uses a low gain voltage mode PWM control for simple application design. An internal 0.8V reference allo.

Features

over current protection, over voltage protection, and under voltage lock-out. The output current is monitored by sensing the voltage drop across the MOSFET’s RDS(ON), which eliminates the need for a current sensing resistor.
