MAX77675AEWE+

MAX77675AEWE+ is a highly efficient, complete power supply for low-power, ultra-compact application. It provides four programmable buck-boost switching outputs using only one inductor. Operating from a single lithium-ion or Lion battery, this device 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 device to be dynamically configured and monitored. This device is part of the single-inductor multiple-output (SIMO) product family. It is used in applications such as TWS Bluetooth™ headphones/hearables, fitness, health, activity monitors, and smart watches, portable devices, sensor nodes and consumer internet of things or IoT.
