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.
SPECIFICATION All specifications are typical at nominal input, full load at 25°C unless otherwise stated
