DC/DC converters feature wide output ranges

The 100W i3A series of non-isolated DC/DC converters from TDK come packaged in a 1/32nd brick form factor and can adjust from either 3.3 to 16.5V or 5 to 30V output and accept an input voltage of 9 to 53V. 

According to the company, the i3A series can be used to derive additional high power outputs from a single output 12V, 24V, 36V or 48V supply at a much lower cost than traditional isolated DC/DC converters.

With efficiencies of up to 98%, the step-down converters are suited for use in medical, communications, industrial, test and measurement, broadcast and portable equipment.

Measuring 19.1 x 23.4 x 9.6mm, the i3A can operate in temperatures of -40 to 125°C. The thermal design of the series is said to allow for minimal output de-rating, even with low airflow and high ambient temperature conditions. According to the company, the product’s optimised dynamic voltage response reduces the need for external capacitors.

Standard features for the i3A series include a trim pin for output voltage adjustment, + remote sense, remote on-off, input under-voltage, over-current and over-temperature protection.

All models have safety certification to the IEC/EN 60950-1 and UL/CSA 60950-1 standards with CE marking for the Low Voltage and RoHS2 Directives.
