EV6908-J-00A

EV6908-J-00A is an evaluation board designed for the MP6908, a low-drop diode emulator IC. When combined with an external switch, the MP6908 replaces Schottky diodes in high-efficiency flyback converters. The MP6908 regulates the forward drop of an external synchronous rectifier (SR) MOSFET to about 40mV, which switches off once the voltage becomes negative. The MP6908 can generate its own supply voltage for battery charging applications, with a low output voltage for high-side rectification applications. Configurable ringing detection circuitry prevents the MP6908 from false turn on during discontinuous conduction mode (DCM) and quasi-resonant operation. Suitable for USB PD quick chargers, adapters, flyback power supplies with low and/or, variable output voltage applications.

• Wide output range down to 0V
• No need for auxiliary winding for high-side or low-side rectification
• Ringing detection prevents false turn on during DCM and quasi-resonant operations
• Works with standard and logic level SR MOSFETs
• Compatible with energy star
• 30ns fast turn-off and turn-on delay
• 100µA quiescent current
• Supports DCM, CCM and quasi-resonant operations
• Supports high-side and low-side rectification
