Analog Devices / Maxim Integrated MAX77675 SIMO PMIC

Analog Devices MAX77675 SIMO PMIC is a highly efficient, complete power supply engineered for low-power, ultra-compact applications. The MAX77675 offers four programmable buck-boost switching outputs using only one inductor. The device operates from a single lithium-ion or Li-ion battery, producing a total of 700mA output current (3.7V_IN, 1.8V_OUT) housed in less than a 40mm² solution size.

The ADI MAX77675 PMIC features an integrated sequencer that controls a complete startup, while an I²C interface allows dynamic configuration and monitoring. The MAX77675 is part of the single-inductor multiple-output (SIMO) product family.
