ree or four LEDs up to 30.2mA each. Featuring individual low resistance, low drop-out voltage current sinks, the AHK3294 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. Skyworks' Simple Serial Control™ (S2Cwire™) interface is used to enable, disable, and set the LED drive current for 32-level linear scale LED brightness control. For flexible control the maximum LED current of up to 30.2mA per channel is set via an external resistor.
