DC/DC Converter TBA 1 Series, 1 Watt
• Continuous short circuit protection
• I/O isolation: 1’500 VDC
• 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 plastic package
• Unregulated outputs
• 3-year product warranty
The TBA 1 is an elementary 1 Wat t DC/DC SIP converter series which is specifically de-
signed to of fer a low-cost solution with no concession on quality and lifetime. The new
design improves on the industr y standard features and offers an integrated continuous
short circuit protection circuit, an operating temperature range from –40°C to 85°C with-
out derating and I/O-isolations of either 1’500 VDC. It offers a broad application range in
any space and cost critical application.
