The 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).

STRF6456 Pinouts


• Oscillator is provided on the monolithic control with adopting On-ChipTrimming technology.

• Small temperature characteristics variation by adopting a comparator to compensate for
temperature on the control part.

• Low start-up circuit current (100uA max)

• Built-in Active Low-Pass Filter for stabilizing the operation in case of light load
