MP6908L Datasheet | Monolithic Power Systems

Fast Turn-Off Intelligent Rectifier with No Auxiliary Winding Requirement DESCRIPTION The MP6908L is a low-drop diode emulator IC. When bined with an external switch, the MP6908L can replace Schottky diodes in highefficiency flyback converters. The MP6908L regulates the forward drop of an external synchronous rectifier (SR) MOSFET to about 40m V, then switches off once the voltage bees negative. The MP6908L can generate its own supply voltage for battery charging applications that can have low output voltage or short-circuit output conditions, as well as high-side SR configuration. Configurable ringing detection circuitry prevents the MP6908L from false turnoff after VDS oscillates in discontinuous conduction mode (DCM), or during quasiresonant operation. The MP6908L is available in a space-saving TSOT23-6 package. Features - Wide Output Voltage Range Down to 0V, No Short-Circuit Current Flows through the Body Diode - Auxiliary Winding for High-Side or Low-Side Rectification is Not Required - Ringing Detection Prevents False Turn-On in DCM and Quasi-Resonant Operations - Works with Standard and Logic-Level SR MOSFETs - patible with Energy Star - 30ns Fast Turn-Off and Turn-On Delay - 100µA Quiescent Current - Supports DCM, CCM, and Quasi-Resonant Operation - Supports Both High-Side and Low-Side Rectification - Available in a TSOT23-6 Package APPLICATIONS - USB PD Quick Chargers - Adapters - Flyback Power Supplies with Very Low and/or Variable Output Voltages All MPS parts are lead-free, halogen-free, and adhere to the Ro HS directive.
