The 3637 series design allows for a
range of products which give not only a
high current rating, but minimizes the
board space required for this product.
Tyco Sigma quality, matched with
reliability and low cost make this series
suitable for many applications in power
line DC-DC conversion. The low height
profile of the components make this
series also suitable for hard disk
drives, notebook PC’s and other
electronic equipment.
