FAN5610
LED Driver for Four Parallel-Connected LEDs

The FAN5610 features constant current source matching across the LEDs for brightness consistency, and can support up to four parallel LEDs. Unlike competitors' products, this driver gives designers the flexibility of using V_F-matched or V_F-unmatched LEDs. A built-in digital/analog converter provides digital and PWM brightness control. No external parts are needed for current matching. The FAN5610 is available in an 8-lead MLP package. For pricing and availability information, visit www.fairchildsemi.com/pf/FA/FAN5610.html. A FAN5610 demo board is also available. Please contact your local sales representative for more information.
