SQ6601PT
Off-Line Quasi-Resonance Flyback Switching Regulator
Description
The SQ6601PT is a hybrid IC consists from power MOSFET and a controller IC, designed for Indirect feed-back
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. the device is provided in a five pin over-
molded TO-220 style package, affording dielectric isolation without compromising thermal characteristics.
(Note). PRC is abbreviation of “Pulse Ratio Control” (On-width control with fixed OFF-time).
Features
