Overview

TopologyBuck Converter
Input voltage6-40 V
Output 10.67 A
IC revisionA

Description

The IS31LT3360 is a continuous mode inductive step-down converter, designed for driving a single LED or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage. The chip operates from an input supply between 6V and 40V and provides an externally adjustable output current of up to 1.2A.

Features

  • Up to 1.2A output current
  • High efficiency (up to 98%)
  • Wide input voltage range: 6V ~ 40V
  • Internal 40V power switch
  • Simple low parts count
  • Typical 3% output current accuracy (-40°C to +105°C, IS31LT3360-SDLS3-TR)
  • Typical 5% output current accuracy (-40°C to +125°C, IS31LT3360-SDLS4-TR)
  • Single pin on/off and brightness control using DC voltage or PWM
  • Up to 1MHz switching frequency
  • Inherent LED open-circuit/short-circuit protection
  • Thermal shutdown protection circuitry
  • Up to 1200: 1 dimming ratio
  • RoHS & Halogen-Free Compliance
  • TSCA Compliance

Typical applications

  • Automotive and avionic lighting, LED MR16, MR11 spotlight, LED streetlight, PAR light, Industrial lighting, Refrigeration lights, Other LED lighting
