The 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 feature four 2:1 input range variants: seven of the models have 4.5-10 V input; seven have 9–18 V inputs; seven have 18–36 V inputs; seven have 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.
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). They can accommodate an ambient operating temperature range of -40 to 85 degrees Celsius with suitable derating. Offering up to 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.
AYA 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, overload protection (fold back) and continuous (hiccup mode) protection against output short-circuit.
