General Description

The MAX77680/MAX77681 is a 3-channel single-inductor multiple-output (SIMO) buck-boost regulator that regulates three independent rails using only 3μA of quiescent current (IQ).

The SIMO improves battery life by replacing inefficient LDOs while being competitive in efficiency to traditional single-output bucks.

The SIMO operates on a input supply between 2.7V and 5.5V.
