General Description
The MIC2829 is a highly integrated Power Management Integrated Circuit (PMIC) designed for 3G/4G (HEDGE/LTE and WiMAX) USB wireless applications. It is a complete power management solution which provides power to processors, dual standard RF (such as HEDGE/LTE or WiMAX) transceivers and power amplifiers, memory, USB-PHY associated I/O interfaces and other system requirements.
