WebThis feature makes a discontinuous conduction mode possible and avoids reverse conduction of the synchronous rectifier in parallel operation of the converter. The … 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.
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.
