Advanced Energy / Artesyn LGA-D Non-Isolated PCB Mounted PoL Converters

Advanced Energy / Artesyn LGA-D Non-Isolated PCB Mounted Point-of-Load (PoL) Converters are ideal for space-efficient applications and comprise non-isolated DC-DC converters. Each unit features two independent configurable outputs of 25A, 50W, or 40A, 100W, that can be merged into a single 50A, 100W, or 80A, 200W, output. By paralleling up to four units, users can create a power rail that delivers up to 200A or 320A. Regardless of configuration, the input range is 7.5V to 14V, while the adjustable output voltage of 0.6VDC to 5.2VDC maintains a peak efficiency of 95.5% via PMBus® or an external resistor. Advanced Energy / Artesyn LGA-D PoL Converters are suitable for networking, telecom, enterprise computing, and test and measurement applications.
