MAX77658AANX+

MAX77658AANX+ is an ultra-low power PMIC featuring single inductor, 3-output buck-boost, 2-LDOs, power path charger, and fuel gauge for small Li+. It provides highly-integrated battery charging and power supply solutions for low-power applications where size and efficiency are critical. The IC features a SIMO buck-boost regulator that provides three highly-efficient and independently programmable power rails from a single inductor to minimize total solution size. Two 150mA LDOs provide ripple rejection for audio and other noise-sensitive applications. The LDOs can also be configured as load switches to manage power consumption by disconnecting external blocks when not required. A highly configurable linear charger supports a wide range of Li+ battery capacities and includes battery temperature monitoring for additional safety (JEITA). Application includes Bluetooth headphones, hearables, wireless speakers, wearables, safety and security monitors, sensor nodes, internet of things.
