The i6A4W step-down converters are the 20-A versions of the i6A product family of non-isolated dc/dc converters. They operate from an input voltage from 9 to 53 V and deliver an output voltage adjustable from 3.3 to 15 V. They can operate from 48-V inputs and can be used as drop-in replacements for isolated 1/16th converters (33 x 22.9 x 12.7 mm) driving 12-V point-of-load (PoL) devices in medical, communications, industrial, and test and measurement equipment.
The step-down converters can also be used with single-output 12-, 24-, 36-, and 48-V output ac/dc power supplies to generate additional regulated high-current outputs, with or without battery backup. With efficiencies of up to 97%, power losses are minimized, allowing the products to operate in harsh ambient temperatures of −40°C to 125°C, even with low airflow requirements.The basic feature models include an output voltage adjustment pin, positive or negative logic remote on-off, remote sense, input under-voltage, over-current, and thermal protection. Full feature models are equipped with a power good signal, output voltage sequencing, and the ability to synchronize the operating frequency to minimize system noise.
