High Efficiency Synchronous Rectification EV Board
The EV6902A+MP6907-S_J-00A is an evaluation board for the MP6902A and MP6907. It is configured to provide synchronous rectification solution for flyback.
MP6902A and MP6907 features a synchronous gate output which enables high efficiency rectification by replacing the schottky rectifier with a low Ron MOSFET. MP6907 has the wider VDD range and stronger driving capability than MP6902A.

- <300μA/150μA (MP6902A/MP6907) Quiescent Current atLightLoad Mode
- Supports CCM, CrCM and DCM Operation Mode
- Supports High-side and Low-side Rectification
Fast Turn-off Flyback Synchronous Rectifier that Supports CCM, DCM and QR Operation Modes
The MP6907 is a low-drop diode emulator controller IC that, when combined with an external MOSFET, can replace Schottky diodes in high-efficiency flyback converters. The MP6907 regulates the forward drop of an external switch to about 70mV, which switches off once the voltage becomes negative.
The MP6907 provides a SYNC interface to receive an external signal to shut down the gate driver for reliable continuous conduction mode (CCM) operation. A programmable light-load sleep mode can reduce the IC’s quiescent current to ~150μA.
The MP6907 is available in compact SOIC8 and TSOT23-6 packages.
Fast Turn-off Intelligent Rectifier MP6902 in a TSOT23-6 Package
The MP6902A is a low-drop diode emulator IC for flyback converters, which replaces Schottky rectification diodes to achieve high efficiency when combined with an external switch.
The MP6902A regulates the forward drop of an external switch to about 70mV and switches it off as soon as the voltage becomes negative. The MP6902A has a light-load sleep mode that reduces the quiescent current to 300µA.
High Noise Immunity, Fast Turn-off Intelligent Rectifier for Flyback
The MP6901 is a Low-Drop Diode Emulator IC that, combined with an external switch replaces Schottky diodes in high-efficiency, Flyback converters. The chip regulates the forward drop of an external switch to about 70mV and switches it off as soon as the voltage becomes negative. Package choices are a space saving TSOT23-5 or SOIC-8.
