The AHK3294 is a linear current-sink LED driver, capableof driving one, two, three or four LEDs up to 30.2mAeach. Featuring individual low resistance, low drop-outvoltage current sinks, the AHK3294 allows the LEDs tobe regulated directly from a Lithium Ion/Polymer batterywithout the need for an additional step-up power supply,thereby reducing the external component count, eliminatingswitching noise and maximizing efficiency.
