DATA SHEET AAT2608A Eight-Channel LDO with DC/DC Converter General Description 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 dropout (LDO) regulators, making it ideal for general multiple rails applications. The step-down converter is a 800mA synchronous converter 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 compensation 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.
