DC/DC Converter TBA 1 Series, 1 Watt

  • Continuous short circuit protection
  • I/O isolation: 1'060 VAC
  • Operating temperature range -40 to +85 °C without derating
  • Input voltage ranges (±10%): 3.3, 5, 12, 24 VDC
  • High efficiency up to 82%
  • SIP-4 package
  • Unregulated outputs
  • 3-year product warranty The TBA 1 is a 1 Watt DC/DC SIP converter series which is specifically de- signed to offer a low-cost solution with no concession on quality and lifetime. The new design improves on the industry standard features and offers an inte- grated continuous short circuit protection circuit, an operating temperature range from –40°C to 85°C without derating and I/O-isolation of 1’500 VDC. It offers a broad application range in any space and cost critical application. Models Order Code Input Voltage Output Voltage Output Current Efficiency Range nom. max. typ.
