SP6089 Datasheet (SYNC POWER) - Synchronous Rectifier Driver

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
