General Description
The AHK3294 is a linear current-sink LED driver, capable of driving one, two, three 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 vi...
