LNK4023S Datasheet Cv/cc Switcher

Manufacturer: Power Integrations

Overview: LinkSwitch-4 Family Energy-Efficient, Accurate Primary-Side Regulated CV/CC Switcher for Adapters and Chargers Product Highlights Dramatically Simplifies CV/CC Converters • Eliminates optocoupler and all secondary CV/CC.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

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

The LinkSwitch-4 family adaptive BJT drive technology uses combined base and emitter switching to boost switching performance and deliver higher efficiency, wider Reverse Bias Safe Operating Area (RBSOA) margin and the flexibility to accommodate a wide range

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.
