3 Watt Isolated DC-DC Converters For Industrial Uses


Artesyn Embedded Technologies launched a new series of ultra-compact 3 watt DC-DC converters measuring 0.55 x 0.55 x 0.32 inch, designed for diverse low power applications, including data and telecommunication, instrumentation, computer peripheral equipment, industrial automation and mobile battery-powered systems.

The new Artesyn AYA series of isolated DC-DC converters comprises 28 variants, each of which is available in a mini dual-in-line package with through-hole mounting terminations.

The converters come with four 2:1 input range variants. Seven models have 4.5-10 V input, seven have 9–18 V inputs,  seven have 18–36 V inputs and seven come with 36-75 V inputs.

Within each of these input categories, there is a choice of four single output models, offering voltages of 3.3 V, 5 V, 12 V and 15V, and three dual output models offering +5/-5 V, +12/-12 V or +15/-15 V.


The converters are offered in an ultra-compact 0.55 x 0.55 x 0.32 inch plastic case. Ambient operating temperature range is specified from -40 to 85 degrees Celsius with suitable derating.

Featuring 87 percent conversion efficiency, the converters use 100 kHz fixed frequency switching to minimize the need for external EMI filtering and comply with the EN 55022 class A and FCC level A standards for conducted noise.

Models with output voltages of 5 V or higher are rated at 3 watts power output, whereas the four 3.3 V models are rated at 2 watts.

Standard features include 1,500 Vdc input/output isolation, overload protection (fold back) and continuous (hiccup mode) protection against output short-circuit.
