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