AAT3120

3-Channel Charge Pump

For White LED Applications

™

ChargePump

General Description

Features

The AAT3120 is a low noise, constant frequency

charge pump DC/DC converter that uses fractional

(1.5X) conversion to improve efficiency for white

LED applications. The device can be used to pro-

duce eight current levels up to 20mA per channel

for up to three channels. 1X load switch mode is

also built-in to improve efficiency at low current set-

tings. Low external parts count (two 1µF flying

capacitors and two small 1µF capacitors at V_INand

OUT) makes the AAT3120 ideally suited for small

battery-powered applications.

V_INRange: 2.7V to 5.5V

Fractional Charge Pump Mode

Drives Low-V_Fand High-V_FType LEDs

Up to Three LED Outputs

— Single Wire Programming

— Eight Regulated Current Settings

— Max 20mA per Channel

Low Noise Constant Frequency Operation

No Inductors

1MHz Switching Frequency

Small Application Circuit

Automatic Soft-Start

I_Q<1µA in Shutdown

12-Pin TSOPJW Package

•

AnalogicTech's S²Cwire™ (Simple Serial Control™)

serial digital input is used to enable, disable, and

set current for each LED at eight different levels.

The AAT3120 has a thermal management system

to protect the device in the event of a short-circuit

condition at the output pin. Built-in soft-start circuit-

ry prevents excessive inrush current during start-

up. A high charge pump switching frequency

enables the use of very small external capacitors.

A low current shutdown feature disconnects the

load from V_INand reduces quiescent current to less

than 1µA. The AAT3120 is available in the very

small Pb-free 12-pin TSOPJW package.
