Flyback switching loss
WebTPS55340 includes an integrated 40-V, 5-A low-side MOSFET switch for boost, SEPIC or flyback applications. This example design demonstrates the TPS55340 in a flyback topology. An opto-coupler ... switching losses hurting … WebTherefore, the loss of the switch transistor during the initial conduction period (t d and t r) and the turn-off period (t s and t f) is all larger than that of the flyback switch-mode power supply. One way to reduce the switching losses is to minimize the turn-on/off time of the transistor as much as possible, especially the turn-off time, and ...
