Improved characteristics at lower-costs for popular style of 1W DC-DC converter

22-07-2019 | Traco Power | Power

Traco Power has released their TBA 1 series of 1W DC-DC converters in an industry-standard SIP-4 package measuring 0.46" x 0.24" x 0.38". This style of DC-DC converter is extensively used to offer isolation between low-power circuits and has long been the most common type of converter. The TBA 1 series provides enhanced performance characteristics allowing engineers to accomplish design improvements while gaining advantage of reduced costs.


The device enhances isolation from the standard 1000VDC up to 1500VDC; expands the full load operating temperature range to -40C to +85C (older designs need de-rating); incorporates integrated short-circuit protection; increased efficiencies up to 82% (typically 5% lower on older designs); and improved reliability up to two million hours (per MIL-HDBK-217F at +25C, ground benign). Standard features include 3.3/5/12/24V inputs with ±10% input range; and single outputs of 3.3/5.1/12/15VDC. 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 the company's three-year warranty.
