MP6908AGJ Overview
Key Specifications
Package: VSSOP
Operating Voltage: 5 V
Max Voltage (typical range): 13 V
Min Voltage (typical range): 4 V
Description
The MP6908A is a low-drop diode emulator IC that, when combined with an external switch, replaces Schottky diodes in high-efficiency flyback converters. The MP6908A regulates the forward drop of an external synchronous rectifier (SR) MOSFET to about 40mV, which switches off once the voltage becomes negative.
Key Features
- Supports DCM, CCM, Quasi-Resonant Operations and Active Clamp Flyback
- Supports up to 600kHz Switching Frequency
- Wide Output Range down to 0V, No Short Circuit Current Flows through Body Diode
- No Need for Auxiliary Winding for High-Side or Low-Side Rectification
- Ringing Detection Prevents False Turn-On during DCM and Quasi-Resonant Operations
