DESCRIPTION：

Miniature surface mounted DC/DC Converters are an ideal and economical solution for many

applications where noise reduction, voltage isolation, voltage conversion in distributed power systems

is required. these converters are qualified for the higher temperatures requested by lead-free reflow

solder processes, especially for automated SMD production lines.
