In the 20 to 75W power range, the need to meet increasingly tight efficiency and stand-by requirements for auxiliary power supplies has pushed the use of quasi-resonant topologies replacing more mainstream fly-back based designs.
We offer a range of power MOSFETs, diodes as well as primary PWM controllers together with an extensive range of hardware and software evaluation and development tools including reference designs to help design high-efficiency auxiliary switch mode power supplies (SMPS).
