It is a high-performance synchronous rectifier control circuit on the secondary side of a switching power supply.
The SP6534FB 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 Tier 6 energy efficiency standards 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 rectifier device temperature.
The chip integrates a 45V NMOSFET synchronous rectifier switch with very low internal resistance, with a typical RdsON as low as 8mΩ, providing a system output of up to 3.4A; it also integrates high-voltage direct detection technology with a voltage rating up to 150V; and a supply voltage up to 30V, allowing the controller to be directly used in 5V output voltage rectification applications.
The highly integrated circuit design makes the chip's external circuitry extremely simple. In 5V applications, only one capacitor is needed to build a complete synchronous rectification system.
