AHK3296 Six-Channel 1x Low Dropout LED Driver

The AHK3296 is a linear current-sink LED driver, capable of driving up to six LEDs at 20.6mA each. Featuring individual low resistance, low drop-out voltage current sinks, the AHK3296 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. To minimize the use of external components the LED current is set internally to a maximum of 20.6mA. The AHK3296 is packaged in a Pb-free, 10-pin SC70JW or 10-pin TDFN2x2.2 package and operates over the -40°C to +85°C temperature range.
