LNK306DG-TL

AC/DC转换器, 降压, 降压-升压, 反激式, 85V至265VAC输入, 225mA, SOIC-8

* MDCM2: 225 mA * 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 simplified 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 filter cost * High thermal shutdown temperature +135 °C minimum Much Higher Performance Over Discrete Buck and Passive Solutions * Supports buck, buck-boost and flyback topologies * System level thermal overload, output short-circuit and open control loop protection * Excellent line and load regulation even with typical configuration * 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 efficiency than passive solutions * Higher power factor than capacitor-fed solutions * Entirely manufacturable in SMD EcoSmart™– Extremely Energy Efficient * Consumes typically only 50/80 mW in self-powered buck topology at 115/230 VAC input with no-load opto feedback * Consumes typically only 7/12 mW in flyback topology with external bias at 115/230 VAC input with no-load * Meets California Energy Commission CEC, Energy Star, and EU requirements
