The MAX77847 is a highly efficient high-performance buck-boost regulator with an industry-leading quiescent current of 14μA targeted for battery-powered applications. It supports an input voltage range from 1.8V to 5.5V and an output voltage range from 1.8V to 5.2V. The IC provides two programmable switching current limits to optimize external component sizing based on load requirements. Analog Devices’ unique buck-boost controller technology provides high efficiency, excellent load and line transient performance, and a seamless mode transition across the input and output range.The device features a hardware configuration SEL pin which configures the default output voltage and I2C target address. A hardware dynamic voltage scaling (DVS) pin allows the user to change the output voltage between two output voltages without I2C interference. The I2C interface is optional and allows users to adjust the output voltage with 50mV steps.The MAX77847 is available in a 2.18mm x 1.66mm 15-bump wafer-level package (WLP).APPLICATIONS5G PA SupplyBattery Power EquipmentInternet of Things (IoT) DevicesSystem Power Pre-RegulationSmartphones ToF/Facial and Gesture Recognition
