DESCRIPTION

The high performance 20A UIS48T20033 DC-DC converter provides a high efficiency single output, in a 1/16 th brick package.
Specifically designed for operation in systems that have limited airflow and increased ambient temperatures, the UIS48T20033 converter utilizes the same pinout and Input/Output functionality of the industry-standard sixteenth bricks. In addition, a baseplate /heat spreader feature is available (-xDxBx suffix) that provides an effective thermal interface for coldplate and heat sinking options.
The UIS48T20033 converter thermal performance is accomplished through the use advanced circuits, packaging, and processing techniques to achieve ultra-high efficiency, excellent thermal management, and a low-body profile.
Operating from a wide-range 18-75V input, the UIS48T20033 converter utilizes digital control and provides a fully regulated 3.3V output voltage. The designer can expect reliability improvement over other available converters because of the UIS48T20033’s optimized thermal efficiency.
