DC/DC Converter TMR 2WI Series, 2 Watt

  • Ultra-wide 4:1 input range
  • SIP-9 package
  • Temperature range –40 to +85°C
  • High efficiency
  • Excellent load and line regulation
  • Indefinite short-circuit protection
  • I/O isolation 1500 VDC
  • Remote On/Off control
  • Fully RoHS compliant
  • 3-year product warrenty The TMR 2WI series is a new family of isolated 2W DC/DC converter modules with regulated output, featuring ultra-wide 4:1 input voltage ranges of 9-36 VDC or 18-75 VDC. The product comes in a ultra-compact SIP-9 plastic pack- age. An excellent efficiency up to 84% allows –40°C to +85°C operation tempera- tures at full load. Further features include remote On/Off control and continu- ous short circuit protection. Typical applications for these ultra-compact con- verters are battery operated equipment and distributed power architectures in communication, instrumentation and industrial electronics, everywhere where space on the PCB is critical.
