The TDR 3WI series is a family of compact 3 W DC/DC-converters with 4:1 in-
put voltage ranges and tightly regulated output voltages even under no load
conditions. The product is available in THD-package. They work with high effi-
ciency over the full load range and come with a remote On/Off input. The us-
ability in temperature ranges of up to +85°C, continuous short circuit protec-
tion and excellent immunity against environmental influences make these con-
verters very reliable. A TDR 3WI converter is the ideal solution for space critical
high end applications in communication equipment, instrumentation and indus-
trial electronics.
