About This Product

■Summary

The MP6909 is a low voltage drop diode emulator IC that, when combined with an external switch, replaces a Schottky diode in a high efficiency flyback converter. The MP6909 regulates the forward drop of an external synchronous rectifier (SR) MOSFET to approximately 40mV and switches off when the voltage goes negative. MP6909 can generate its own supply voltage through an internal linear regulator. A programmable ringing detection circuit prevents the MP6909 from accidentally turning on with VDS oscillations during discontinuous conduction mode (DCM) and quasi-resonant operation. The MP6909 is offered in a space-saving TSOT23-6 package.

■Features and benefits

・Internally regulated supply voltage ・Ringing detection prevents false turn-on during DCM and quasi-resonant operation - Works with standard and logic level SR MOSFETs ・Energy Star compatible ・Fast turn-off and turn-on delay of less than 30ns ・Static current less than 100μA ・Supports DCM, CCM, and quasi-resonant operation ・Supports high side and low side rectification ・Provided in TSOT23-6 package

■Available product numbers

・MP6909GJ-P MP6909GJ-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
