LNK304GN-TL Datasheet PDF - Power Integrations

● MDCM2: 120 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
