DC/DC Converter TMR 3 Series, 3 Watt Wide 2:1 input voltage range Fully regulated output voltage Compact SIP-8 package 1600 VDC I/O isolation (functional insulation) UL 62368-1 IEC 62368-1 UL 60950-1 IEC 60950-1 Small footprint Temperature range 40 to +85C The TMR 3 series is a new family of isolated 3 W DC/DC converter modules with regulated output, featuring wide 2:1 input voltage ranges. The product High efficiency up to 85% comes in a compact SIP-8 plastic package with a small footprint occupying only 2.0 cm (0.3 square inch) of board space. An excellent efficiency allows 40 Short-circuit protection to +85C operation temperatures. Further features include remote On/Off con- Remote On/Off control trol and continuous short circuit protection. The compact dimensions of these converters make them an ideal solution for many space critical applications in 3-year product warranty communication equipment, instrumentation and industrial electronics.
