AAT3129

High Efficiency 1X/1.5X/2X Charge Pump

for RGB Color LED Applications

™

ChargePump

General Description

Features

The AAT3129 is a high efficiency charge pump

DC/DC converter with tri-mode load switch (1X)

fractional (1.5X) and doubling (2X) conversion for

color LED applications. A single current source out-

put provides a regulated current to drive R, G, and

B LEDs via three internal switches. With a simple

single wire serial bus, the RGB module can be eas-

ily controlled to display 4096 colors.

AnalogicTech's Advanced Simple Serial Control™

(AS²Cwire™) serial digital input is used to enable,

disable, and set the duty cycle of each internal

MOSFET switch. Low external parts count (two

1μF flying capacitors and two small bypass capac-

itors at V_INand OUT) makes the AAT3129 ideally

suited for small battery-powered applications.

Applications

The AAT3129 has a thermal management system

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

condition on any of the output pins. Built-in soft-

start circuitry prevents excessive inrush current

during start-up. High switching frequency enables

the use of small external capacitors. A low current

shutdown feature disconnects the load from V_IN

and reduces quiescent current to less than 1μA.
