LNK405EG - LED Driver IC

Download the LNK405EG datasheet PDF. This datasheet also covers the LNK403EG variant, as both devices belong to the same led driver ic family and are provided as variant models within a single manufacturer datasheet.

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.
