UCC24630 동기화 정류기 컨트롤러

Texas Instruments UCC24630 Synchronous Rectifier Controller is a high-performance controller and driver for N-channel MOSFET power devices used for secondary-side synchronous rectification (SR). The combination of a controller and MOSFET emulates a near-ideal diode rectifier. This solution directly reduces power dissipation of the rectifier. It also reduces primary-side losses due to compounding of efficiency gains. Utilizing a volt-second balancing control method, the UCC24630 is ideal for flyback power supplies. This is especially true over wide-output voltage ranges since the device is not connected directly to the MOSFET drain. The wide V_DD operating range, wide programming range of the VPC voltage and blanking time, allows use in a variety of flyback converter designs.
