The new Artesyn ATA series of 3 watt isolated DC-DC converters comprises 16 variants, each of which is available in a mini dual-in-line package for through-hole mounting or a mini surface-mount package.

All ATA series converters feature ultra-wide 4:1 inputs; eight of the models have 9-36V inputs and the other eight have 18–75V inputs. Within each of these two categories, there is a choice of five single output models, offering voltages of 3.3V, 5V, 12V, 15V or 24V, and three dual output models offering +5/-5V, +12/-12V or +15/-15V.

Fully encapsulated in an ultra-compact 0.94 x 0.54 inch (24 x 13.7 mm) plastic case, the converters have a height of just 0.32 inch (8 mm). The surface-mount versions accommodate an ambient operating temperature range of -40 to 80C, while the through-hole versions can handle temperatures from -40 to 85C, both with suitable derating.

Offering up to 80% conversion efficiency, the converters use 350kHz fixed frequency switching to minimise the need for external EMI filtering and comply with the EN 55022 class A and FCC level A standards for conducted noise.

Artesyn ATA series converters with output voltages of 5V or higher are rated at 3W power output; the four 3.3V models are rated at 2W. Standard features include 1500 volts of direct current (Vdc) input/output isolation, remote on/off and continuous protection against output short-circuit.
