LNK403EG - LED Driver IC

General 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.

Key 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.
