WebThe Synchronous rectifier will be required to achieve a power loss reduction of ∆Ploss, where ∆Ploss is typically greater than 50%. The typical forward voltage drop VF of a 150V diode at elevated temperature of 100°C is around 800mV. For a given power loss reduction ∆Ploss dissipated in the secondary side switch, the required MOSFET WebThe flyback transformer circuit was invented as a means of controlling the horizontal movement of the electron beam in a cathode ray tube (CRT). Unlike conventional transformers, a flyback transformer is not fed with a signal of the same waveshape as the intended output current. WebMaxim Integrated MAX17691A and MAX17691B Isolated Flyback Converters are high-efficiency no-opto integrated nMOSFET flyback converters that uses fixed frequency peak current mode control.
