Part Number: STR-F6454
Function: Hybrid IC, INTEGRATED SWITCHER ( Power MOSFET and a controller IC )
Package: Zip 5 Pin
Manufacturer: Sanken Electric co.,ltd.
The STRF6454 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).
• 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
