LNK353

www.DataSheet4U.com LNK353/354 ® LinkSwitch-HF Family Product Highlights 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 High bandwidth provides fast turn on with no overshoot and excellent transient load response Current limit operation rejects line frequency ripple Built-in current limit and hysteretic thermal shutdown protection EcoSmart – Extremely Energy Efficient No-load consumption <300 mW without bias winding at 265 VAC input Meets California Energy Commission (CEC), Energy Star, and EU requirements Applications Chargers for ...
