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 +85°C
  • High efficiency up to 82%
  • Excellent load and line regulation
  • Short-circuit protection
  • I/O isolation 1600 VDC
  • Remote On/Off control
  • 3-year product warranty IEC 62368-1UL 62368-1 The TMR 3WI series is a new family of isolated 3W DC/DC converters with reg- 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 cm² (0.3 square inch) of board space. An excellent efficiency allows –40° to +85°C 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.
