DATA SHEET  
AAT2608A  
Eight-Channel LDO with DC/DC Converter  
General Description  
Features  
•
The AAT2608A is a member of Skyworks' Total Power  
Management IC (TPMICTM) product family. It contains a  
fully integrated step-down converter and eight low drop-  
out (LDO) regulators, making it ideal for general multiple  
rails applications.  
1.5MHz Step-Down Converter  
800mA, Externally Adjustable  
Synchronous with Integrated Switches  
Independent Enable  
Independent Input Power and Ground  
▪
▪
▪
▪
Operating Input Voltage Range of 2.7V to 5.5V  
▪
The step-down converter is a 800mA synchronous con-  
verter which operates at a switching frequency of 1.5MHz,  
minimizing the size of external components while keeping  
efficiency greater than 90%. The step-down converter is  
capable of 1A of peak current and has an integrated com-  
pensation network. The input voltage range is 2.7V to  
5.5V, and the output can be externally adjusted from 0.6V  
to 80% of the step-down converter's input voltage. It  
includes an independent enable to provide a convenient  
solution to implement any power up or power down  
sequencing.  
•
LDO1, LDO2, LDO3 and LDO4 Regulators Share Same  
Input as the Step-down Converter  
LDO5 and LDO6 are Tied to the Same Input  
LDO7 and LDO8 are Tied to the Same Input  
LDO1, LDO7 and LDO8 have Adjustable Outputs with  
External Resistors  
•
•
•
•
•
LDO2, LDO3, LDO4, LDO5 and LDO6 have Factory  
Programmed Outputs  
All LDOs have:  
Independent Enable  
300mA Current Capability  
High PSRR (68dB @10KHz)  
Low Ground Current (30µA)  
Over-Current Protection  
Over-Temperature Protection  
Operating Input Voltage Range from 2.7V to 5.5V  
▪
▪
The AAT2608A has eight high-PSRR LDOs which provides  
noise immunity to the generated power rails. The LDOs  
have independent enable pins to meet any power-up or  
power-downsequencingrequirements. EachLDOrequires  
a small output ceramic capacitor for stability. 5 of the  
LDOs have a fixed output which is programmed during  
manufacturing; 3 LDOs have adjustable outputs pro-  
grammable with external resistors. LDOs 1, 2, 3 and 4  
share the same input voltage as the step-down con-  
verter’s control circuitry. LDO5 shares its input with  
LDO6; LDO7 shares its input with LDO8.
