DESCRIPTION
The SP7614 driver family provides matched current source bias for white, blue or any color LEDs.
The current in the LEDs can be programmed by an external resistor. The Individual LED currents
are 200 x ISET, where ISET is the current through the external resistor connected to the CTRL
pin. The SP7614is designated to drive two high current LEDs. The SP7614 is offered in a 6-
pin SC-70 package.
