● 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
