LNK409EG - LED Driver IC

Download the LNK409EG datasheet PDF (LNK403EG included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for led driver ic.

Description

The LinkSwitch-PH dramatically simplifies implementation of LED drivers requiring PF >0.9, TRIAC dimmer capability and high efficiency.

The single-stage PF and constant current controller eliminates passive circuitry required for power factor correction and electrolytic bulk capacitor.

Features

  • Auto-restart for short-circuit protection.
  • Open circuit fault detection mode.
  • Automatic thermal shutdown restart with hysteresis.
  • Meets high voltage creepage requirement between DRAIN and all other signal pins both on PCB and at package EcoSmart®.
  • Energy Efficient.
  • Low standby power remote ON/OFF feature (85% achievabl.
