AYA series converters have four 2:1 input range variants: seven of the models have 4.5-10V input; seven have 9-18V inputs; seven have 18-36V inputs; seven have 36-75V inputs. Within each of these input categories, there is a choice of four single output models, offering voltages of 3.3V, 5V, 12V and 15V, and three dual output models offering ±5V, ±12V or ±15 V. Fully encapsulated in a 14 x 14 mm plastic case, the converters have a height of 8 mm. They can accommodate an ambient operating temperature range of -40 to 85C with suitable derating. Offering up to 87% 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.
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 1,500 Vdc input/output isolation, overload protection (fold back) and continuous (hiccup mode) protection against output short-circuit.
