The RT9202B is a single power supply PWM DC-DC converter controller designed to drive N-MOSFET in a synchronous buck topology. The IC integrates the control, output adjustment, monitoring and protection functions in a small 8-pin package. The RT9202B uses a low gain voltage mode PWM control for simple application design. An internal 0.8V reference allows the.
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.
