Bel Power Solutions UIQ High-Performance DC-DC Converters
Bel Power Solutions UIQ High-Performance DC-DC Converters offer a high-efficiency single output, in a 1/4 brick package. These 20A, 48A, and 72A converters are specifically designed for operation in systems that have limited airflow and increased ambient temperatures. The UIQ series utilizes the same pinout and input/output functionality of industry-standard quarter bricks. A heat spreader (-xDxBx suffix) provides an effective thermal interface for cold-plate and heat-sinking options. Bel Power Solutions UIQ High-Performance DC-DC Converters operate from a wide 18V to 75V input range and provide a fully regulated 3.3V, 5V, and 12V output voltage as well as optimized thermal efficiency.
