Description: 5V to 12V Single Synchronous Buck PWM Controller

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 reg

Applications

* An oscillator with fixed frequency 300kHz reduces the component size of the external inductor and capacitor for saving PCB board area and cost. The RT8109 supports both tracking and stand-alone loop control modes. Standalone mode is simple and tracking mode provides better flexibility. The RT8109 a
