The key design challenge for an LED lighting driver and battery charger focuses on higher efficiency, lower temperature and lower cost. Quasi-Resonant (QR) flyback converters are very popular for low-power applications because of the simplicity and low cost. Low stored energy in the output capacitance; EOSS and the low switching losses of the MOSFET are critical factors needed for optimal flyback converter efficiency. The new 800-V SUPERFET(r) III MOSFET is optimized for use as a primary side switch, since it enables lower switching losses and low case temperature without sacrificing EMI performance due to its optimized design.
