SILICON LABORATORIES EFP01 Energy Friendly PMICs | New Product BriefOctober 02, 2020 by Mouser Electronics
This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.
The Silicon Labs Energy Friendly Power portfolio are a line of PMICs specifically designed as companion chips for the Energy Friendly Radio chip portfolio to extend the battery life of wireless IoT devices.
Silicon Labs EFP01 Energy Friendly PMICs are highly flexible and efficient PMICs ideal for ultra-low-power IoT devices and are compatible with multiple battery types. EFP01 PMICs operate at up to 94$ efficiency from a wide input voltage range and have very low quiescent current. They provide four outputs covering voltages from 0.8V to 5.2V, including one buck-boost, one buck plus LDO, one LDO, and one switched output that can be used to complete power down high leakage circuits.
The EFP01 PMICs also include a coulomb counter that provides lossless measurement of charge into the load. Output voltage, inrush current, and other settings are fully programmable via I2C.
