AAT1232

24V 100mA Step-Up Converter

™

SwitchReg

General Description

Features

The AAT1232 is a high frequency, high efficiency

boost converter capable of 24V maximum output

voltage. The internal power switch can deliver

100mA load current. It is the ideal power solution to

power OLED, LCD, and CCD applications operat-

ing from a single cell lithium-ion battery.

Package

The high switching frequency (up to 2MHz) pro-

vides fast response to load transients with small

external components. The fully integrated control

IC simplifies the design while reducing the total

PCB footprint. The AAT1232 offers a true load dis-

connect feature which isolates the load from the

power source when EN/SET is pulled low. This

eliminates leakage current and maintains zero volt-

age at the output while disabled.

•

The output voltage can be dynamically set by acti-

vating one of two reference levels (FB1 or FB2)

through the SEL logic pin. Optionally, AnalogicTech’s

Simple Serial Control™ (S²Cwire™) interface pro-

vides dynamic programmability across a wide output

voltage range through the EN/SET pin.

•

-40°C to +85°C Temperature Range

Applications

The AAT1232 is available in a Pb-free, thermally-

enhanced 16-pin 3x4mm TDFN low-profile pack-

age or a Pb-free 12-pin TSOPJW package.
