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% Excellent load and line regulation Short-circuit protection UL 62368-1 IEC 62368-1 UL 60950-1 IEC 60950-1 The TMR 3WI series is a new family of isolated 3W DC/DC converters with regulated 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 cm (0.3 square inch) of board space. An excellent efficiency allows -40 to +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 equipment and instrumentation.
