Datasheet Summary
Single Synchronous Buck PWM DC-DC Controller
General Description
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 allows the output voltage to be precisely regulated to low voltage requirement. A fixed 300kHz oscillator reduces the ponent size for saving board space.
The RT9202 Features over current protection, over voltage protection, and under voltage lock-out. The output...
