The MAX77655 is a highly efficient, complete power supply for low-power, ultra-compact applications. It provides four programmable buck-boost switching regulator outputs using only one inductor. Operating from a single Li-ion battery, the MAX77655 delivers a total of 700mA output current (3.7V_IN, 1.8V_OUT) in less than 40mm² solution size.

An integrated sequencer controls full startup while an I²C interface allows the MAX77655 to be dynamically configured and monitored.

This device is part of the single-inductor multiple-output (SIMO) product family.
