DAK-54: 2.75W, 5V @ 480mA, 85 ~ 265VAC

Summary

Design Accelerator Kits (DAK) provide all of the essential materials to get you started on your next switch mode power supply design. The kits include a fully assembled and tested prototype power supply board, comprehensive engineering report, product samples, unpopulated circuit board, data sheet and other related documentation.

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
