About This Product

■Summary

The MP6908A is a low voltage 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 approximately 40mV and switches off when the voltage goes negative. The MP6908A can generate its own supply voltage for battery charging applications where the output voltage may be low. The MP6908A can also generate this voltage under shorted output conditions or in a high-side synchronous rectification configuration. A programmable ringing detection circuit prevents the MP6908A from accidentally turning on with VDS oscillations during discontinuous conduction mode (DCM) and quasi-resonant operation. The MP6908A is offered in a space-saving TSOT23-6 package.

■Features and benefits

・Supports DCM, CCM, quasi-resonant operation, active clamp flyback ・Supports switching frequency up to 600kHz ・Wide output width down to 0V, no short circuit current through body diode ・No auxiliary winding required for high-side or low-side rectification ・Ringing detection prevents false turn-on during DCM and quasi-resonant operation - Works with standard and logic level synchronous rectification MOSFETs ・Compliant with Energy Star ・Fast turn-off and turn-on delay of less than 30ns ・Static current less than 100μA ・Supports high side and low side rectification ・Provided in TSOT23-6 package

■Available product numbers

・MP6908AGJ-P MP6908AGJ-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
