General Description

The IS31LT3350 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 750mA.

Depending upon supply voltage and external components, this can provide up to 30 watts of output power.

Key Features

  • Simple low parts count.
  • Internal 40V power switch.
  • Wide input voltage range: 6V to 40V.
  • Up to 750mA output current (SOT89-5 package).
  • High efficiency (up to 95%).
  • Typical 1200：1 dimming ratio.
  • Typical 5% output current accuracy.
  • Single pin on/off and brightness control using DC voltage or PWM.
  • Up to 1MHz switching frequency.
  • Inherent open-circuit LED protection.
  • Thermal shutdown protection circuitry.
  • Two packages available for differen.
