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.
