General Description
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.
Key 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.
