WebDescription The MP6908 is a low-drop diode emulator IC that, when combined with an external switch, 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. WebA very interesting solution is the Flyback with Synchronous Rectification ([2] and [3]). Synchronous Rectification provides three important benefits to the Flyback topology: 1. Magnetizing current can be negative, hence DCM is avoided and the output voltage is regulated even under no load conditions. 2. ZVS can be achieved with a proper design. 3. how do i know if a pokemon is shiny
