FAN5612
LED Driver for Three Parallel-Connected LEDs + Enable

Part of Fairchild’s new family of low-cost LED drivers, the FAN5612 can drive up to three parallel LEDs, and has an enable/shutdown control that allows the supply current to drop to less than 1µA when not in use. This driver’s separate control inputs for analog and PWM brightness controls provide unsurpassed flexibility and performance. No external parts are required to ensure brightness consistency. The FAN5612 driver is available in two space-saving packages: a 6-lead SC-70, and a 6-lead TSOT. For pricing and availability information, visit www.fairchildsemi.com/pf/FA/FAN5612.html. A FAN5612 demo board is also available. Please contact your local sales representative for more information.
