DC/DC Converters
TDR 2 Series, 2 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 -40C to +85C
without derating

I/O isolation 1500 VDC Continuous short-circuit protection Remote On/Off control Fully RoHS compliant 3-year product warranty
The TDR-2 series is a family of compact 2 W dc/dc-converters with 2:1 input voltage 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 85C without power derating, continuous short circuit protection and excellent immunity against environmental influences make these converters very reliable. A TDR-2 converter is the ideal solution for space critical high end applications in communication equipment, instrumentation and industrial electronics.
