LNK302/304-306 LinkSwitch™-TN Family Lowest Component Count, Energy-Efficient Off-Line Switcher IC 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 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 overlo
