General Description

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 consumer communications equipment.

Channel 1 is a step-down regulator with an input voltage range of 6.0V to 24V, providing up to 4.5A output current.
