TDK Corporation announces the introduction of the 250 W, TDK-Lambda i6A series of non-isolated, DC-DC converters. Capable of operating from an input voltage of 9 V to 40 V, the step-down converter delivers an output voltage that can be adjustable from 3.3 V to 24 V and output currents of up to 14 A. The series is designed to be used in a wide range of applications including medical, communications, industrial, and test and measurement equipment.

In a 1/16th brick form factor, measuring 33 mm x 22.9 mm x 12.7 mm, the converters can be used in conjunction with a single output 12 V or 24 V AC-DC power supply to generate additional regulated high current outputs, with or without battery back-up. The open-frame, compact, design features a low profile and weight that allow for extremely flexible and robust manufacturing processes. The ultra-high efficiency allows for a high-output power rating that is truly usable, even in demanding thermal environments.
With efficiencies of up to 98%, power losses are minimized, allowing the products to operate in harsh, ambient temperatures of -40°C to +125°C, even with low-airflow requirements. The need for external output capacitance is reduced due to an optimized dynamic voltage response, thus reducing board space requirements. The i6A24014A033V utilizes a low component count that results in both a low cost structure and a high level of performance.
The basic-feature models include an output voltage adjustment pin, positive or negative logic remote on-off, remote sense, input under-voltage, over-current, and thermal protection. Full feature models are equipped with a power-good signal, output voltage sequencing, and the ability to synchronize the operating frequency to minimize system noise. All models are certified to UL/CSA 60950-1, IEC/EN 60950-1 and carry the CE mark for the Low-Voltage and RoHS2 directives.
