DATA SHEET  
AAT1146  
FastTransient 400mA Step-Down Converter  
General Description  
Features  
The AAT1146 SwitchReg is a 1.4MHz step-down con-  
verter with an input voltage range of 2.7V to 5.5V and  
output voltage as low as 0.6V. It is optimized to react  
quickly to a load variation.  
• VIN Range: 2.7V to 5.5V  
• VOUT Fixed or Adjustable from 0.6V to VIN  
• 27μA No Load Quiescent Current  
• Up to 98% Efficiency  
• 400mA Max Output Current  
• 1.4MHz Switching Frequency  
• 120μs Soft Start  
• Fast Load Transient  
• Over-Temperature Protection  
• Current Limit Protection  
The AAT1146 is available in fixed voltage versions with  
internal feedback and a programmable version with  
external feedback resistors. It can deliver 400mA 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.  
• 100% Duty Cycle Low-Dropout Operation  
• <1μA Shutdown Current  
The AAT1146 is designed to maintain high efficiency  
throughout the operating range, which is critical for por-  
table applications.  
• SC70JW-8 and SOT23-5 Packages  
Temperature Range: -40°C to +85°C  
The AAT1146 is available in the Pb-free, space-saving  
2.0 x 2.2mm SC70JW-8 and SOT23-5 packages and is  
rated over the -40°C to +85°C temperature range.  
Applications  
• Cellular Phones  
• Digital Cameras  
• Handheld Instruments  
• Microprocessor / DSP Core / IO Power  
• PDAs and Handheld Computers
