Description

General part information

MAX77348 Series

The MAX77348 is an ultra-low quiescent current, noninverting buck-boost converter capable of supporting up to 3.5W output power. The device employs a unique control algorithm that seamlessly transitions between the buck, buck-boost, and boost modes, minimizing discontinuities and subharmonics in the output voltage ripple.The MAX77348 is ideal for a system handling less than 3.5W output power from a single cell Li-Ion battery and requiring high system efficiency with precise voltage control. The MAX77348’s low-noise operation makes it optimum to supply power for RF system power, ear bud applications, and other portable audio systems.Built-in undervoltage lockout (UVLO), output active discharge, and thermal shutdown protection ensures safe operation under abnormal operating conditions. The MAX77348 is available with a highly configurable I2C serial interface. The device is available in 16-bump, 1.77mm x 2.01mm, 0.4mm pitch WLP package.APPLICATIONSTrue Wireless Stereo (TWS) SystemsNarrow Band Internet of Things (NB IoT)Portable Audio/Wireless Systems
