SP6089 - Synchronous Rectifier Driver
The SP6089 is a low-drop diode emulator IC, which when it combined with an external switch replaces Schottky diodes in high-efficiency flyback converters.
The SP6089 generates its own supply voltage and does not need auxiliary winding for either high-side or lowside applications.
Programmable ringin
SP6089 Features
* Does not need auxiliary winding for either high-side or low-side applications
* Fast turn-on and turn-off delay
* Ringing detection prevents false turn-on during DCM and QR operations
* Less than 100mW standby power
