DC/DC Converters
TDR 3 Series, 3 Watt
Features
◆
Compact design in SMD or DIP package
◆ Wide 2:1 input voltage range
◆ Fully regulated outputs
◆ Low ripple and noise
◆ No minimum load required
◆ Temperature range –40°C to +85°C

The TDR-3 series is a family of compact 3 W DC/DC converters with 2:1 input volt-
age ranges and tightly regulated output voltages even under no load conditions.
The product is available in SMD-package or in DIP-package. They work with high
efficiency over the full load range and come with a remote On/Off input.
The usability in temperature ranges of up to 85°C, continuous short circuit protec-
tion and excellent immunity against environmental influences make these converters
very reliable.
A TDR-3 converter is the ideal solution for space critical high end applications in
communication equipment, instrumentation and industrial electronics.
