Integrated Switcher - International Rectifier

IRIS-F6456S is a hybrid IC consists from Power MOSFET and a controller IC, designed for Quasi-Resonant (including low frequency PRC) fly-back converter type SMPS (Switching Mode Power Supply) applications. This IC realizes high efficiency, low noise, downsizing and standardizing of a power supply system reducing external components count and simplifying the circuit designs. (Note). PRC is abbreviation of Pulse Ratio Control (On-width control with fixed OFF-time). By International Rectifier Corp.
