SOUTHCHIP/南芯 SC3512HSEER SOP-8 快速关断同步整流器

Description
SC3512 is a smart secondary-side synchronous rectifier. It integrates a 60V power MOSFET. SC3512 can replace Schottky diode so the system can achieve higher efficiency.
The SR MOSFET is turned on when the VVD falls below turn-on threshold, and turned off when the VVD exceeds turn-off threshold. The SR conduction voltage drop is continuously monitored to minimize the conduction loss. The extremely fast turn-off comparator and driving circuitry ensures the safety of the system, even in current continuous mode (CCM) condition.
This chip supports both high side rectification and low side rectification.

SC3512HSEER Features
■ No need of auxiliary winding for power supply
