DC/DC Converter TMR 3WI Series, 3 Watt Highest power density in SIP package Ultra wide 4:1 input range Small footprint: 21.8 x 9.2 mm Temperature range 40 to +85C High efficiency up to 82% UL 62368-1 IEC 62368-1 Excellent load and line regulation UL 60950-1 IEC 60950-1 Short-circuit protection The TMR 3WI series is a new family of isolated 3W DC/DC converters with reg- I/O isolation 1600 VDC ulated output, featuring ultra-wide 4:1 input voltage range. The product comes in a ultra-compact SIP plastic package with a small footprint occupying only 2.0 Remote On/Off control cm (0.3 square inch) of board space. An excellent efficiency allows 40 to 3-year product warranty +85C operation temperatures. Further features include remote On/Off control and continuous short circuit protection. The very compact dimensions of these converters make them an ideal solution for many space critical applications in battery-powered equip- ment and instrumentation.
