General Description
The AAT1230 is a high frequency, high efficiency
boost converter capable of 18V 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.
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 the total PCB footprint. The AAT1230
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 SELlogic pin. Optionally, AnalogicTech’s
Simple Serial Control (S
2
Cwire) single wire
interface provides dynamic programmability across
a wide output voltage range through the EN/SETpin.
The AAT1230 is available in a Pb-free, thermally-
enhanced 16-pin 3x4mm TDFN low-profile pack-
age or a Pb-free 12-pin TSOPJW package.
