AAT2688 4.5A PMIC

The AAT2688 provides two independently regulated DC outputs: a high voltage synchronous step-down (Buck) regulator and a low input voltage step-down low dropout (LDO) regulator. The PMIC is optimized for low cost 12V adapter inputs, making the device the ideal system-ona-chip power solution for cons.

AAT2688 Features

* 2-Output Step-Down Converters:
