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 output voltage to be precisely regulated to low voltage requirement. A fixed 300kHz oscillator reduces the component size for saving board space. The RT9202B 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.
