Power Integrations LNK353
Low Power Off-Line Switcher IC
FEATURES
Optimized for Lowest System Cost● Fully integrated auto-restart for short-circuit and open loop protection
● Self-biased supply – saves transformer auxiliary winding and associated bias supply components
● Tight tolerances and negligible temperature variation on key parameters eases design and lowers cost
● High maximum switching frequency allows very low flux density transformer designs, practically eliminating audible noise
● Frequency jittering greatly reduces EMI
● Packages with large creepage to high voltage pin
● Lowest component count switcher solution Much Better Performance over Linear/RCC
● Lower system cost than RCC, discrete PWM and other integrated solutions
● Universal input range allows worldwide operation
● Simple ON/OFF control – no loop compensation needed
● No bias winding – simpler, lower cost transformer
● High frequency switching – smaller and lower cost transformer
● Very low component count – higher reliability and single side printed circuit board
