RT9209A - Synchronous Buck PWM DC-DC

Download the RT9209A datasheet PDF. This datasheet also covers the RT9209 variant, as both devices belong to the same synchronous buck pwm dc-dc family and are provided as variant models within a single manufacturer datasheet.

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.

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 indicator.
