DC/DC Converters TDR 3WI Series, 3 Watt Features Compact design in SMD or DIP package Ultra wide 4:1 input voltage range Fully regulated outputs Low ripple and noise No minimum load required Temperature range -40C to +85C I/O isolation 1600 VDC Continuous short-circuit protection Remote On/Off control Fully RoHS compliant 3-year product warranty UL 60950-1 The TDR-3WI series is a family of compact 3 W DC/DC converters with 4:1 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, continuous short circuit protection and excellent immunity against environmental influences make these converters very reliable. A TDR-3WI converter is the ideal solution for space critical high end applications in communication equipment, instrumentation and industrial electronics.
