Low I SIMO PMIC with 0.5V to 5.5V Outputs Delivering Up to 700mA Total Output Current

The MAX77675 is a highly efficient, complete power supply for low-power, ultra-compact applications. It provides four programmable buck-boost switching outputs using only one inductor. Operating from a single lithium-ion or Li-ion battery, the MAX77675 delivers a total of 700mA output current (3.7VIN, 1.8VOUT) in less than 40mm2 solution size.

An integrated sequencer controls full startup while an I2C interface allows the MAX77675 to be dynamically configured and monitored.

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