DATA SHEET  
AAT2512  
Dual 1.4MHz, 400mA Synchronous Buck DC/DC Converter  
Features  
General Description  
The AAT2512 is a member of Skyworks' Total Power  
Management IC (TPMIC™) product family. It is a dual  
channel synchronous buck converter operating with an  
input voltage range of 2.7V to 5.5V, making it ideal for  
applications with single-cell lithium-ion/polymer batter-  
ies.  
VIN Range: 2.7V to 5.5V  
Output Current:  
Channel 1: 400mA  
Channel 2: 400mA  
98% Efficient Step-Down Converter  
Integrated Power Switches  
100% Duty Cycle  
Both regulators have independent input and enable pins.  
Offered with fixed or adjustable output voltages, each  
channel is designed to operate with 27μA (typical) of  
quiescent current, allowing for high efficiency under light  
load conditions.  
1.4MHz Switching Frequency  
Internal Soft Start  
150μs Typical Turn-On Time  
Over-Temperature Protection  
Current Limit Protection  
The AAT2512 requires only three external components  
(CIN, COUT, and LX) for each converter, minimizing cost  
and real estate. Both channels are designed to deliver  
400mA of load current and operate with a switching fre-  
quency of 1.4MHz, reducing the size of external compo-  
nents.  
Available in TDFN33-12 Package  
-40°C to +85°C Temperature Range  
Applications  
Cellular Phones  
Digital Cameras  
Handheld Instruments  
Microprocessor / DSP Core/ IO Power  
PDAs and Handheld Computers  
The AAT2512 is available in a Pb-free, 12-pin TDFN33  
package and is rated over the -40°C to +85°C tempera-  
ture range.
