The MAX77680/MAX77681 is a 3-channel single-inductor multiple-output (SIMO) buck-boost regulator designed for low-power applications such as wearables and IoT gadgets. It regulates three independent rails using only 3μA of quiescent current and operates on an input supply between 2.7V and 5.5V. The device features a flexible power sequencer to control the power-up and power-down order of each output and includes a glitchless transition between buck and boost operation.
