● LT3591 White LED Driver with Integrated Schottky in 3mm × 2mm DFN
DESCRIPTION
The LT®3591 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 a 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 drivers use 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. Few external components are needed: open-LED protection and the Schottky diode are all contained inside a low profile 3mm × 2mm DFN package. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
