DC-DC 3A Mini Buck Module

Product Introduction:

A power module is a power supply that can be directly mounted on a printed circuit board, with two types: buck and boost. Its characteristic is that it can provide power for specialized integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memory, field programmable gate arrays (FPGAs), and other digital or analog loads.

Selecting industrial grade components, combined with years of professional and manufacturing experience, each power module undergoes multiple quality and performance tests before leaving the factory. Ensure the performance and stability of the module, and meet the usage requirements of industrial grade products.
