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 (3.7VIN, 1.8VOUT) 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.
