DC/DC Converter TMU 3 Series, 3 Watt

  • Compact 3 Watt converter in SIP-4 package
  • Continuous short circuit protection
  • Unregulated outputs
  • Operating temperature range -40 to +75 °C without derating
  • I/O isolation: 1’500 VDC
  • Input voltage ranges (±10%): 5, 12, 24 VDC
  • High efficiency up to 86%
  • 3-year product warranty The TMU 3 series consists of a set of isolated 3 Watt DC/DC converters with unregulated outputs in a standard SIP-4 package. They are designed to offer a compact low-cost alternative to regulated series with no concession on quality and lifetime. They feature a continuous short circuit protection circuit, I/O-isola- tion of 1500 VDC and an operating temperature range from –40°C to 75°C without derating. The compact dimensions of these converters make them an ideal solution for many space critical applications in communication equipment, instrumentation and industrial electronics.
