The TBA 1E is a 1 Watt DC/DC SIP converter series which is specifically designed 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 integrated 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.
