The AHK3291 is a linear current-sink LED driver, capable of driving one or two LEDs up to 20.6mA each. Featuring ndividual low resistance, low drop-out voltage current sinks, the AHK3291 allows the LEDs to be regulated directly from a Lithium-Ion/Polymer battery without the need for an additional step-up power supply, thereby reducing the external component count, eliminating switching noise and maximizing efficiency.
