Product Highlights
Cost Effective Linear/Cap Dropper Replacement Lowest cost and component count buck converter solution Fully integrated auto-restart for short-circuit and open loop fault protection – saves external component costs LNK302 uses a simplied controller without auto-restart for very low system cost 66 kHz operation with accurate current limit – allows low cost off-the-shelf 1 mH inductor for up to 120 mA output current Tight tolerances and negligible temperature variation High breakdown voltage of 700 V provides excellent input surge withstand Frequency jittering dramatically reduces EMI (~10 dB) – minimizes EMI lter cost High thermal shutdown temperature (+135 °C minimum) Much Higher Performance over Discrete Buck and Passive Solutions Supports buck, buck-boost and yback topologies System level thermal overload, output short-circuit and open control loop protection Excellent line and load regulation even with typical conguration High bandwidth provides fast turn-on with no overshoot Current limit operation rejects line ripple Universal input voltage range (85 VAC to 265 VAC) Built-in current limit and hysteretic thermal protection Higher efciency than passive solutions Higher power factor than capacitor-fed solutions Entirely manufacturable in SMD EcoSmart – Extremely Energy Efcient Consumes typically only 50/80 mW in self-powered buck topology at 115/230 VAC input with no load (opto feedback) Consumes ty……
