General Description
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.
Key Features
- 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.
