AYA 2 Watt Isolated DC-DC Converter Series

Advanced Energy’s AYA series of 2 W 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 28 variants, each of which is available in a mini dual-in-line package for through-hole mounting or a mini surface-mount package.

All AYA series 2 W converters feature wide input voltage; 7 of the models have 4.5 to 10 V input, 7 have 9 to 18 V inputs, 7 have 18 to 36 V inputs, 7 have 36 to 75 V inputs.

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

Fully encapsulated in an ultra compact 0.55 x 0.55 inch (14 x 14 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 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.

AYA series converters with output voltages of 5 V or higher are rated at 2 W power output; the four 3.3 V models are rated at 1.3 W. Standard features include 1,500 VDC input/output isolation, remote On/Off and continuous (hiccup mode) protection against output short circuit.
