AAT2552  
Total Power Solution for Portable Applications  
SystemPower  
General Description  
Features  
The AAT2552 is a fully integrated 500mA battery  
charger, a 300mA step-down converter, and a  
300mA low dropout (LDO) linear regulator. The  
input voltage range is 4V to 6.5V for the battery  
charger and 2.7V to 5.5V for the step-down con-  
verter and linear regulator, making it ideal for appli-  
cations operating with single-cell lithium-ion/poly-  
mer batteries.  
Battery Charger:  
— Input Voltage Range: 4V to 6.5V  
— Programmable Charging Current up to  
500mA  
— Highly Integrated Battery Charger  
Charging Device  
Reverse Blocking Diode  
Current Sensing  
Step-Down Converter:  
The battery charger is a complete constant cur-  
rent/constant voltage linear charger. It offers an  
integrated pass device, reverse blocking protec-  
tion, high accuracy current and voltage regulation,  
charge status, and charge termination. The charg-  
ing current is programmable via external resistor  
from 30mA to 500mA. In addition to these stan-  
dard features, the device offers over-voltage, cur-  
rent limit, and thermal protection.  
— Input Voltage Range: 2.7V to 5.5V  
— Output Voltage Range: 0.6V to VIN  
— 300mA Output Current  
— Up to 96% Efficiency  
— 45µA Quiescent Current  
— 1.5MHz Switching Frequency  
— 120µs Start-Up Time  
Linear Regulator:  
— 300mA Output Current  
— Low Dropout: 400mV at 300mA  
— Fast Line and Load Transient Response  
— High Accuracy: 1.5%  
— 85µA Quiescent Current  
Short-Circuit, Over-Temperature, and Current  
Limit Protection  
TDFN34-16 Package  
-40°C to +85°C Temperature Range  
The step-down converter is a highly integrated  
converter operating at a 1.5MHz switching fre-  
quency, minimizing the size of external compo-  
nents while keeping switching losses low. The out-  
put voltage ranges from 0.6V to the input voltage.  
The AAT2552 linear regulator is designed for high  
speed turn-on and turn-off performance, fast tran-  
sient response, and good power supply ripple  
rejection. Delivering up to 300mA of load current,  
it includes short-circuit protection and thermal  
shutdown.  
Applications  
®
The AAT2552 is available in a Pb-free, thermally-  
enhanced TDFN34-16 package and is rated over  
the -40°C to +85°C temperature range.
