Description:

Automotive Quasi-Resonant Flyback Controller

Applications

* the converter will be operated with a battery input voltage of 13.5 V. To optimize the performance of the regulator at this voltage, the magnetics can be designed to force 0 V across the MOSFET at turn-on. This minimizes switching losses and perhaps more importantly reduces EMI caused by voltage ri
