This vide o will introduce CUI's Low power isolated DC-DC converters, ranging from 1 to 3 watts. CUI's range of low power converters are available in fixed and wide input voltage ratios. For example, the PDS, PDM, and PEM models offer a fixed input voltage that is ideal when the voltage rail connected to the input is very stable. http://youtu.be/67GCaEEYM0k
