LNK4003D - CV/CC Switcher

This page provides the datasheet information for the LNK4003D, a member of the LNK4002S CV/CC Switcher family.

Datasheet Summary

Description

The LinkSwitchTM-4 family of ICs dramatically simplifies low power CV/CC charger design by eliminating an optocoupler and secondary control circuitry.

Features

  • Dynamic base drive technology provides flexibility in choice of BJT transistor by dynamically optimizing BJT switching characteristics.
  • Extends RBSOA of BJT.
  • Dramatically reduces sensitivity to BJT gain.
  • Compensates for input line voltage variations.
  • Compensates for cable voltage drop.
  • Compensates for external component temperature variations.
  • Very accurate IC parameter tolerances using proprietary trimming technology.
  • Freq.
