AAT2689
Overview
The AAT2689 provides two independently regulated DC outputs, consisting of a high voltage step-down (Buck) regulator and a low input voltage low dropout (LDO) regulator. The PMIC is optimized for low cost 12V adapter inputs, making the device the ideal system-on-a-chip power solution for consumer communications equipment.
