Improvements for Most Popular 1-watt DC-DC Converter Style


Enhanced features include an integrated short-circuit protection circuit

San Jose, Calif. - TRACO POWER has announced the release of their TBA 1 series of 1-watt DC/DC converters in the industry standard SIP-4 package measuring 0.46 x 0.24 x 0.38". This style of DC/DC converter is widely used to provide isolation between low-power circuits and has long been the most common type of converter. The TBA 1 series provide enhanced performance characteristics enabling engineers to achieve design improvements while taking advantage of reduced costs.

The TBA 1 improves isolation from the standard 1,000VDC up to 1,500 VDC; expands the full Load operating temperature range to -40°C to +85°C (older designs require de-rating); includes integrated short-circuit protection; increased efficiencies up to 82% (typically 5% lower on older designs); and improved reliability up to 2 million hours (per MIL-HDBK-217F at +25°C, ground benign). Standard features include 3.3 / 5 / 12 / 24 V inputs with ±10% input range; and single outputs of 3.3 / 5.1 / 12 / 15 VDC. These drop-in replacement designs allow engineers to take advantage of these improved characteristics in both new and existing applications. All models comply with IEC/EN/UL 62368-1 / 60950-1 safety standards and are supported by TRACO POWER's 3-year warranty.

Products are in stock and available through the TRACO POWER global distribution network with manufacturing lead times of 12-14 weeks. Please see  for specifications, drawings and safety documentation.
