General Description

The AAT1230/1230-1 is a high frequency, high effi-

ciency boost converter capable of 18V maximum

output voltage. The internal power switch can deliv-

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

to power OLED, LCD, and CCD applications oper-

ating from a single cell lithium-ion battery.

Hysteretic control provides up to 2MHz switching

frequency and fast response to load transients with

small, low-cost external components. The fully inte-

grated control IC simplifies the design while reduc-

ing the total PCB footprint. The AAT1230/1230-1

offers a true load disconnect feature which isolates

the load from the power source when EN/SET is

pulled low. This eliminates leakage current and

maintains zero voltage 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™ (S

interface provides dynamic programmability across

a wide output voltage range through the EN/SET pin.

The AAT1230/1230-1 are available in a Pb-free,

thermally-enhanced 16-pin 3x4mm TDFN low-pro-

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