Features  
General Description  
•
•
The AAT2601 and AAT2601A are members of Skyworks'  
Total Power Management IC (TPMICTM) product family.  
They contain a single-cell Lithium Ion/Polymer battery  
charger, a fully integrated step-down converter and 5 low  
dropout (LDO) regulators. The device also includes 2 load  
switches for dynamic power path/sleep mode operation,  
making it ideal for small handheld portable GSM or CDMA  
mobile telephones.  
Voltage Regulator VIN Range: 4.5V to 6V  
Complete Power Integration  
Integrated Load Switches to Power Converters from  
AC Adapter or Battery Automatically  
Low Standby Current  
▪
•
•
170μA (typ) w/ Buck (Core), LDO1 (PowerDigital),  
and LDO2 (PowerAnalog) Active, No Load  
One Step-Down Buck Converter (Core)  
▪
1.8V, 300mA Output  
3.3V, 300mA Output (AAT2601A-3.3 ONLY)  
1.5MHz Switching Frequency  
▪
The battery charger is a complete thermally regulated  
constant current/constant voltage linear charger. It  
includes an integrated pass device, reverse blocking pro-  
tection, high accuracy current and voltage regulation,  
charge status, and charge termination. The charging  
current, charge termination current, and recharge volt-  
age are programmable with an external resistor and/or  
by a standard I2C interface. The AAT2601 has a typical  
battery under-voltage lockout of 2.35V and the AAT2601A  
has a typical battery under-voltage lockout of 2.9V.  
▪
▪
▪
Fast Turn-On Time (100μs typ)  
Five LDOs Programmable with I2C  
•
•
LDO1: 3.0V, 300mA (PowerDigital)  
LDO2: 3.0V, 150mA (PowerAnalog or PLL)  
LDO3: 3.0V, 150mA (TCXO)  
LDO4: 3.0V, 150mA (TX)  
LDO5: 3.0V, 150mA (RX)  
PSRR: 60dB@10kHz  
Noise: 50μVrms for LDO3, LDO4, and LDO5  
▪
▪
▪
▪
▪
▪
The step-down DC/DC converter is integrated with internal  
compensation and operates at a switching frequency of  
1.5MHz, thus minimizing the size of external components  
while keeping switching losses low and efficiency greater  
than 92%. All LDO output voltages are programmable  
using the I2C interface.  
▪
One Battery Charger  
Digitized Thermal Regulation  
Charge Current Programming up to 1.4A  
Charge Current Termination Programming  
Automatic Trickle Charge for Battery Preconditioning  
▪
▪
▪
▪
(2.8V Cutoff)  
The five LDOs offer 60dB power supply rejection ratio  
(PSRR) and low noise operation making them suitable for  
powering noise-sensitive loads.

Adapter OK (ADPP) and Reset (RESET) Timer Outputs  
AAT2601 Typical UVLO: 2.35V  
AAT2601A Typical UVLO: 2.9V  
Separate Enable Pins for Supply Outputs  
Over-Current Protection  
All six voltage regulators operate with low quiescent cur-  
rent. The total no load current when the step-down con-  
verter and 2 LDOs are enabled is only 170μA.  
Over-Temperature Protection  
5x5mm TQFN55-36 Package  
The AAT2601 and AAT2601A are available in a thermally  
enhanced low profile 5x5x0.75mm 36-pin TQFN package.
