DC/DC Converter TDR 3SM Series, 3 Watt Compact design in SMD package Wide 2:1 input voltage range Fully regulated outputs Low ripple and noise Temperature range 40C to +85C without derating UL 62368-1 IEC 62368-1 UL 60950-1 IEC 60950-1 I/O isolation 1600 VDC The TDR 3SM series is a family of compact 3 W DC/DC-converters with 2:1 in- Continuous short-circuit protection put voltage ranges and tightly regulated output voltages even under no load Remote On/Off control conditions. The product is available in SMD-package. They work with high effi- ciency over the full load range and come with a remote On/Off input. The us- Fully RoHS compliant ability in temperature ranges of up to 85C, continuous short circuit protection 3-year product warranty and excellent immunity against environmental influences make these convert- ers very reliable. A TDR 3SM converter is the ideal solution for space critical high end applications in communication equipment, instrumentation and indus- trial electronics.
