DR SERIES Single and dual output Recommended for new design-ins * * * * * * * * The DR Series is a family of dual in line packaged DC/DC converters. It has a unique combination of three high performance features wide input voltage range, high efficiency, and high power density. In addition to this, all outputs are regulated and isolated from the input. This performance is made possible by implementing a 200kHz switching design in hybrid technology. With input voltage ranges of 18-36V, 36-72V and 80% typical efficiency, these devices are ideally suited for on-board logic or analog circuits supplied by telecom distributed power voltages, and for cellular and portable telecommunications systems.

Maximum figure, at full load. Maximum. Low line to high line. Full load to 0.25% full load; dual outputs loaded equally. Standard specifications are conservative and can be optimised for specific applications. In particular, converter start-up at lower than specified temperature, wider input voltage range and output voltage adjustment are all relatively simple modifications to the standard product. Consult factory for details. Fixed frequency design provides for easier input filtering and better noise performance.
