LNK4003D - CV/CC Switcher

Download the LNK4003D datasheet PDF. This datasheet also covers the LNK4002S variant, as both devices belong to the same cv/cc switcher family and are provided as variant models within a single manufacturer datasheet.

General Description

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

Key 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.
