PRODUCT DATASHEET

AHK3296

PowerLinear

6 Channel 1x Low Dropout LED Driver

General Description

Features

•

The AHK3296 is a linear current-sink LED driver, capable

of driving up to six LEDs at 20.6mA each. Featuring indi-

vidual 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.

2.7V to 5.5V Input Supply Range

Drives up to 6 LEDs at up to 20.6mA each

Low-Drop Out, Low Resistance Current Sinks

Typically 40.5mV at Full Scale

Two Package Options:

▪

AnalogicTech’s Simple Serial Control™ (S²Cwire™) inter-

face 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 cur-

rent is set internally to a maximum of 20.6mA.

•

The AHK3296 is packaged in a Pb-free, 10-pin SC70JW

or 10-pin TDFN2.2x2.2 package and operates over the

-40°C to +85°C temperature range.
