Product Overview

The LT3591EDDB#TRMPBF is a fixed frequency step-up DC/DC Converter specifically designed to drive up to ten white LEDs in series from a Li-ion cell. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors. The device features unique high-side LED current sense that enables the part to function as a one wire current source, one side of the LED string can be returned to ground anywhere, allowing a simpler one wire LED connection. Traditional LED driver uses a grounded resistor to sense LED current, requiring a 2-wire connection to the LED string. The high switching frequency allows the use of tiny inductors and capacitors. A single pin performs both shutdown and accurate LED dimming control.
  • Internal Schottky diode
  • One pin dimming and shutdown
  • 42V Open LED protection
  • 1MHz Switching frequency
  • ±5% Reference accuracy
  • Requires only 2.2µF output capacitor
