DC DC Converters - PCB Mount

Fixed input, unregulated dc dc converters offer a simple, ultra low cost solution for the generation of additional power rails, where a regulated primary voltage is already available.  Relec Electronics offer a wide range of very competitively priced, industry standard footprint, low power dc dc converters, now available as fully RoHS compliant products.  Nearly all of the unregulated dc dc converters listed below are specified from -40 to +85 degrees centigrade and units with input to output isolation values of 1kV, 3kV, 6kV & 12kV are available as standard products, with many products available on a 4 week lead-time.    

We also offer a wide range of fully regulated converters with fixed input and wide inputs (2:1 range & 4:1 range) as well as industry standard brick formats.
