Product Description
SP6566AFD is a high-performance synchronous rectifier control circuit for secondary-side switching power supplies. In low-voltage, high-current switching power supply applications, it easily meets the requirements of Level 6 energy efficiency and is an ideal solution for ultra-low conduction voltage drop rectifier devices. The chip supports switching frequency applications up to 150KHz and supports switching power supply operating modes such as CCM/QR/DCM. The extremely low conduction voltage drop results in significantly lower power loss compared to Schottky diodes, greatly improving system conversion efficiency and significantly reducing the temperature of the rectifier device.
The chip integrates a 60V NMOSFET synchronous rectifier switch with extremely low internal resistance, providing a system output of up to 3A; it also integrates high-voltage direct detection technology with a voltage rating of up to 150V; and self-powered technology greatly expands the output voltage application range.
