UM3502QA Datasheet (Union Semiconductor) - Synchronous Step-Down Converter

UM3502QA, Synchronous Step-Down Converter

The UM3502QA is a complete power conversion solution requiring only two low cost ceramic MLCC caps.

Inductor, MOSFETs, synchronous rectifier and control IC are integrated into a tiny 4mm×4mm×1.05mm QFN package.

The UM3502QA is engineered to simplify design and to minimize layout constraints.
