SwitchReg
General Description
The AAT1120 SwitchReg is a 1.5MHz 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 AAT1120 the ideal choice for portable
applications.
The AAT1120 delivers up to 500mA of load current,
while maintaining a low 30
μ
Ano load quiescent cur-
rent. The 1.5MHz switching frequency minimizes
the size of external components, while keeping
switching losses low. The AAT1120 feedback and
control delivers excellent load regulation and tran-
sient response with a small output inductor and
capacitor.
The AAT1120 is available in a Pb-free, 8-pin, 2x2mm
STDFN package and is rated over the -40°C to
+85°C temperature range.
