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
integrated control IC simplifies the design while
reducing

total
AAT1230/1230-1 offers a true load disconnect fea-
ture which isolates the load from the power source
when EN/SET is pulled low. This eliminates leak-
age current and maintains zero voltage at the out-
put while disabled.

footprint.
The
The output voltage can be dynamically set by acti-
vating one of two reference levels (FB1 or FB2)
through the SELlogic pin. Optionally, AnalogicTech’s
Simple Serial Control (S

Cwire) single wire
interface provides dynamic programmability across
a wide output voltage range through the EN/SETpin.
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.
