AHK3294
AHK3294 is Four-Channel LED Driver manufactured by Skyworks Solutions.
Description
The AHK3294 is a linear current-sink LED driver, capable of driving one, two, three or four LEDs up to 30.2m A 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 ponent 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 30.2m A per channel is set via an external resistor.
The AHK3294 is packaged in a Pb-free, 8 pin SC70JW package and is available over a -40 to +85OC temperature range.
