EFP0108GM20-DR

Power Management - Specialized Overview

The EFP0108GM20-DR is a specialized multi-channel Power Management IC (PMIC) from Silicon Labs, designed for ultra-low-power applications. It features a QFN-20 package and operates within an input voltage range of 0.8 V to 5.5 V. The device provides three regulated output rails: Voltage Output A (VOA) adjustable from 1.7 V to 5.2 V via a configurable DC-DC converter; Voltage Output B (VOB) adjustable from 0.8 V to 1.255 V using a buck-only DC-DC converter; and Voltage Output C (VOC) as a linear regulator. It supports single alkaline, dual alkaline, single lithium, and USB power sources.
