DC/DC Converter TBA 1HI Series, 1 Watt
• Continuous short circuit protection
• I/O isolation: 3’000 VDC
• Operating temperature range
-40 to +85 °C without derating
• Input voltage ranges (±10%):
5, 12, 24 VDC

The TBA 1HI is an elementar y 1 Watt DC/DC SIP converter series which is specifically
designed to offer a low-cos t 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 3’000 VDC. It of fers a broad application range in
any space and cost critical application.
