Quasi-resonant conversion is a well established technology which has been extensively used in power supplies in the consumer arena. The new Green FPS family brings the working range of this versatile technology down to the low power range. This design article from Fairchild Semiconductor will describe quasi-resonant flyback and buck converters showing how they improve power supply efficiency.



Air passengers find it annoying, experts claim it is indispensible for flight safety: Entrainment of liquids and gels on board of airplanes is subject to tight restrictions.
