A low-cost, low-dropout LED driver, the FAN5611 can drive up to four LEDs, and supports both analog and PWM brightness controls on the same control input for maximum ease-of-use. No external parts are needed to ensure brightness consistency across the LEDs—an important consideration in designing color displays. The FAN5611 driver is available in two compact packages: a 6-lead SC-70, and a 6-lead TSOT. For pricing and availability information, visit www.fairchildsemi.com/pf/FA/FAN5611.html. A FAN5611 demo board is also available. Please contact your local sales representative for more information.
