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. The internal SMD construction with lead frame technology makes it possible to offer a

product with high performance, these converters are qualified for the higher temperatures requested

by lead-free reflow solder processes, especially for automated SMD production lines.
