<div align="justify">The RT8105A is a synchronous buck PWM controller with embedded MOSFET gate drivers. This part operates with 5V/12V supply voltage, has fixed 300kHz switching frequency, and utilizes voltage mode control. The feedback control loop is compensated internally to simplify the converter design.<br />The RT8105A provides enable/disable function to support power sequence control. This device also provides full fault protection functions to protect the load. This part uses lossless low side MOSFET R<sub>DS(ON)</sub> current sense technique for over current protection with adjustable threshold. Other features include internal soft-start and V<sub>IN</sub> detection function.</div>
