Datasheet Summary
RT9209/A
Synchronous Buck PWM DC-DC with Enable & PGOOD
General Description
The RT9209/A 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 into a small 8-pin package. The RT9209/A uses an internal pensated 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 260kHz/ 400kHz oscillator reduce the ponent size for saving board area. The RT9209/A future a enable control pin to shutdown PWM switching and a 90% power good flag...
