LT3491 - White LED Driver in SC70 with Integrated SchottkyThe LT3491 isA fixed frequency step-up DC/DC converter specifically designed to drive up to six white LEDs in Series fromA 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 featuresA unique high side LED current sense that enables the part to function asA “one wire current source” one side of the LED string can be returned to ground anywher
