ATA Series 3 Watt Isolated DC-DC Converters Series

Artesyn’s ATA series 3 watt isolated DC-DC converters are suitable for a diverse range of low power applications, including data communication, telecommunication and computer peripheral equipment, industrial automation and mobile battery-powered systems. The series 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 3 watt converters feature ultra-wide 4:1 inputs; eight of the models have 9–36 V inputs and the other eight have 18–75 V inputs. Within each of these two categories, there is a choice of five single output models, offering voltages of 3.3 V, 5 V, 12 V, 15 V or 24 V, and three dual output models offering +5/-5 V, +12/-12 V or +15/-15 V.

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 80˚C, while the through-hole versions can handle temperatures from -40 to 85˚C, both with suitable derating. Offering up to 80% conversion efficiency, the converters use 350 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.

ATA series converters with output voltages of 5 V or higher are rated at 3 watts power output; the four 3.3 V models are rated at 2 watts. Standard features include 1,500 Vdc input/output isolation, remote On/Off and continuous (hiccup mode) protection against output short-circuit.
