Part number : STRF6456, STR-F6456
Functions : Hybrid IC, INTEGRATED SWITCHER
Package information : Zip 5 Pin
Manufacturer : Sanken Electric co.,ltd.
STRF6456 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).
