MAX77675
MAX77675 is SIMO PMIC manufactured by Analog Devices.
Description
The MAX77675 is a highly efficient, plete power supply for low-power, ultra-pact applications. It provides four programmable buck-boost switching outputs using only one inductor. Operating from a single lithium-ion or Liion battery, the MAX77675 delivers a total of 700m A 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.
