LNK4215D - CV/CC Switcher

Download the LNK4215D datasheet PDF (LNK4002S included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for cv/cc switcher.

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.
