AN1187: EFP01 Design Considerations

PublishTime：2020-09-23

This application note provides an overview and the theory of operation for the EFP01 Energy Friendly Power Management IC (PMIC). Hardware design recommendations are provided along with a discussion of the software driver and how to integrate it into a EFR32 Wireless Gecko software project.
KEY POINTS：
• EFP01 expands the input supply range of EFR32-based systems.
• EFP01 reduces power consumption of systems that use EFR32 devices without an integrated DCDC converter.
• EFP0111 enables EFR32's radio to operate at higher output power using coin cell batteries.
