Summary and Features

•

Low cost, low component count battery charger/adapter – replaces linear transformer

based solutions

Optimized switching characteristics and low-side configuration of LNK520 minimizes

EMI

Achieves greater than 10 dBµV margin to composite conducted limits

No Y1 safety capacitor required for EMI compliance

Ultra-low earth leakage current, <5 µA

•

Small low cost EE16 transformer

Provision for EE13 transformer for smaller size

Approximate constant voltage, constant current (CV/CC) primary sensed output

characteristic

Efficiency greater than 65% across all line/load conditions

The products and applications illustrated herein (including circuits external to the products and transformer

construction) may be covered by one or more U.S. and foreign patents or potentially by pending U.S. and foreign

patent applications assigned to Power Integrations. A complete list of Power Integrations’ patents may be found
