Cost-Efficient 1W-3W DC-DC Converters

TRACO Power Cost-Efficient 1W-3W DC-DC Converters feature products from the isolated TEA, TBA, and TEC series and the non-isolated TSR 1E series. The converters focus on a simple yet effective design approach to minimize component and labor costs. The devices are available in industry-standard SIP-3, SIP-4, and SIP-7 packages and provide standard I/O isolation of 1500V_DC with options up to 4000V_DC. Available input ranges include wide 2:1, ultra-wide 4:1, and +/-10% of nominal input. The modules have an operating temperature range of -40°C up to +86°C without derating. TRACO Power Cost-Efficient DC-DC Converters are optimized for the Internet of Things (IoT) and feature a three-year warranty. The converters are ideal for space and cost-critical applications and high-volume projects where price and long-term reliability are important.
