DESCRIPTION：

Miniature surface mounted DC/DC Converters are a 0.25W low power and high efficiency DC/DC

converters in SMD package, 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.
