AAT1126
600mA, 1MHz Step-Down Converter
1126.2006.05.1.1

SwitchReg
General Description
The AAT1126 SwitchReg is a member of
AnalogicTech's Total Power Management IC
(TPMIC) product family. It is a 1MHz step-down
converter with an input voltage range of 2.7V to
5.5V and output as low as 0.6V. Its low supply cur-
rent, small size, and high switching frequency
make the AAT1126 the ideal choice for portable
applications.
The AAT1126 is available in either a fixed version
with internal feedback or a programmable version
with external feedback resistors. It can deliver up
to 600mA of load current while maintaining a low
25μA no load quiescent current. The 1MHz switch-
ing frequency minimizes the size of external com-
ponents while keeping switching losses low. The
AAT1126 feedback and control delivers excellent
load regulation and transient response with a small
output inductor and capacitor.
The AAT1126 is designed to maintain high efficien-
cy throughout the operating range and provides
fast turn-on time.
The AAT1126 is available in a Pb-free, space-sav-
ing SOT23-5 package and is rated over the -40°C
to +85°C temperature range.
