Getting Started with EFP01 Power Management IC

The EFP01 Energy Friendly Power Management IC (PMIC) is an extremely flexible, highly efficient, multi-output PMIC, providing complete system power and primary cell battery Coulomb counting for EFM32 and EFR32 devices. EFP01 PMICs operate over a wide input voltage range (0.8 to 5.5 V) with quiescent current as low as 150 nA. EFP01 provides three voltage output rails and four supply outputs – 1x buck/boost converter, 1x buck-only DC-DC converter + LDO, 1x LDO and 1x switched – delivering up to 94% efficiency.
