AAT1110
Fast Transient 800mA Step-Down Converter

SwitchReg
General Description
The AAT1110 SwitchReg is a member of
AnalogicTech's Total Power Management IC
(TPMIC) product family. It is a 1.4MHz step-
down converter with an input voltage range of 2.7V
to 5.5V and output as low as 0.6V. Its low supply
current, small size, and high switching frequency
make the AAT1110 the ideal choice for portable
applications.
The AAT1110 is available in either a fixed version
with internal feedback or a programmable version
with external feedback resistors. It can deliver up
to 800mA of load current while maintaining a low
27μA no load quiescent current. The 1.4MHz
switching frequency minimizes the size of external
components while keeping switching losses low.
The AAT1110 feedback and control delivers excel-
lent load regulation and transient response with a
small output inductor and capacitor.
The AAT1110 is designed to maintain high efficien-
cy throughout the operating range and provides
fast turn-on time.
The AAT1110 is available in a space-saving
2.0x2.1mm SC70JW-8 package and is rated over
the -40°C to +85°C temperature range.
