White Papers

Deep Burst Mode Operation for Reducing Standby Power Consumption without Additional Circuitry  FAN6756 Deep burst mode, one of the power innovations of mWSaver™ technology, is a feedback-control mechanism that reduces standby power consumption in the feedback circuit and switching process by modulating internal parameters of the PWM controller. With this method, the conventional flyback converter topology can be used without additional circuitry.
Dual-Switch Quasi-Resonant Flyback Converter FAN6920MR, FAN7382, FAN6204 A cost effective and reliable alternative to the LLC resonant converter for energy efficiency regulations.
Minimizing Power Losses in the EMI Filter Stage FSB127H Innovative technology that minimizes power losses in the EMI filter stage by eliminating the X-cap discharge resistors, while still meeting UL1950 safety requirements.
