FAN5612 - Fairchild Semiconductor

FAN5612 Low-Dropout LED Drivers

The FAN5611/FAN5612/FAN5613/FAN5614 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 FAN5611 and the FAN5613 are capable of d.
