Description	5V to 12V Single Synchronous Buck PWM Controller
Datasheet	RT8109-Richtek.pdf

The RT8109 is a single-phase synchronous buck PWM DC-DC controller designed to drive two N-MOSFETs.

It provides a highly accurate, programmable output voltage precisely regulated to low voltage requirement with an internal 0.6V ±1% reference.

The RT8109 uses a single feedback loop voltage mode PWM control for fast transient response.

Single IC Supply Voltage ( 5V to 12V).
Drive Two N-MOSFETs.
Fixed Operating Frequency at 300kHz.
Voltage Mode PWM Control with External Feedback Loop Compensation.
Over Current Protection by Sensing MOSFET RDS(ON).
Dual Mode Regulation Control Standalone Mode (FB regulating to close to internal reference 0.6V) Tracking Mode (FB following PI input).
Power Good Indication.
On/Off Control.
Full 0 to 90% Duty Cycle.
RoHS Compliant and Halgen Free.
