AAT2687
Overview
The AAT2687 provides two independently regulated DC outputs; consisting of a high voltage step-down 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.
