MAX77831 Enables USB PD 18W Continuous Power with Fewer Components, Smaller PCB Space and Higher System Efficiency for Systems with Back-Up Battery

By: Simon Lu

摘要 : DC/DC power conversion design can be complicated for systems with a 12V adaptor input along with a backup battery. Common two-stage conversion (boost then buck) can lead to large PCB space, leading to large form factors; complex BOM, low system efficiency and thus, short battery life when in need. MAX77831 simplifies power conversion in such systems by offering single stage, high power density buck-boost conversion to simplify design both in BOM and space, which directly improves system efficiency as well as battery life.
