IS31LT3938 - High Voltage LED Lighting Driver

Datasheet Summary

Description

IS31LT3938 LED driver IC is a peak current detection buck converter which operates in constant off time mode.

It operates over a very wide input voltage supply range of 10VDC to 450VDC or 110VAC/220VAC.

Features

  • User configurable power sequencing levels.
  • 3% output current accuracy.
  • Over current, temperature protection and short circuit protection.
  • High efficiency (typical up to 95%).
  • Higher MOS drive voltage.
  • Wide input voltage range: 10VDC~450VDC or 85Vac~ 265Vac.
  • Linear and PWM dimming.
  • Very few external components.
