LNK603 - Accurate CV/CC Switcher

General Description

The LinkSwitch™-II dramatically simplifies low power CV/CC charger designs by eliminating an optocoupler and secondary control circuitry.

Key Features

  • Compensates for transformer inductance tolerances.
  • Compensates for input line voltage variations.
  • Compensates for cable voltage drop (LNK61X series).
  • Compensates for external component temperature variations.
  • Very tight IC parameter tolerances using proprietary trimming technology.
  • Frequency jittering greatly reduces EMI filter cost.
  • Even tighter output tolerances achievable with external resistor selection/trimming.
