Overview
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 compensated 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 component size for saving board area.
The RT9209/A future a enable control pin to shutdown PWM switching and a 90% power good flag i...
