Artesyn Embedded Technologies has launched its lowest power output DC-DC converters, targeting a diverse range of low-power applications, including data communication, telecommunication and computer peripheral equipment, industrial automation and mobile battery-powered systems. Artesyn's 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 V to 36 V inputs and the other eight have 18 V to 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 V, ±12 V, or ±15 V.

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

Artesyn 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 V_DC input/output isolation, remote on/off, and continuous (hiccup mode) protection against output short-circuit.
