GENERAL 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

APPLICATIONS
● Automotive and avionic lighting
● LED MR16, MR11 spot light
