AAT1120
500mA Step-Down Converter
General Description
Features
SwitchReg
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 30μA no 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.
• VIN Range: 2.7V to 5.5V
• VOUT Range: 0.6V to VIN
• Up to 500mA Output Current
• Up to 96% Efficiency
• 30μA Typical Quiescent Current
• 1.5MHz Switching Frequency
• Soft-Start Control
• Over-Temperature and Current Limit
Protection
• 100% Duty Cycle Low-Dropout Operation
• <1μA Shutdown Current
• Small External Components
• Ultra-Small STDFN22-8 Package
• Temperature Range: -40°C to +85°C

1. The AAT1120 is guaranteed to meet performance specifications over the -40°C to +85°C operating temperature range and is assured
by design, characterization, and correlation with statistical process controls.
2. Output voltage tolerance is independent of feedback resistor network accuracy.
