General Description

The IS31LT3380 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 voltage between 8.5V and 40V and provides an output current up to 1.2A.

The IS31LT3380 includes a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current.

Key Features

  • Multi-modes switch dimming.
  • Up to 1.2A output current.
  • High efficiency (up to 98%).
  • Wide input voltage range: 8.5V to 40V.
  • Internal 40V power switch.
  • Simple low parts count.
  • Typical 5% output current accuracy.
  • Up to 1MHz switching frequency.
  • Inherent LED open-circuit/short-circuit protection.
  • Thermal shutdown protection circuitry.
  • SOP-8 package.
