STMicroelectronics EVL599IND-250W Demonstration Board
STMicroelectronics EVL599IND-250W Demonstration Board is a 250W 24V AC-DC converter designed for industrial applications where minimum size and high efficiency are required. This board features a two-stage approach architecture that combines a front-end transition-mode PFC preregulator and a downstream LLC resonant half-bridge converter. The converter includes a motherboard with a power-factor-correction stage and an LLC resonant-tank stage, as well as three daughterboards. This board offers a 90VAC to 265VAC input voltage range and 300W maximum peak output power. The EVL599IND-250W demonstration board meets EN-61000-3-2 Class-D and JEITA-MITI Class-D standards. This board is available in 165mm x 65mm dimensions with a 30 mm maximum height. Typical applications include industrial AC-DC converters, adapters, and consumer SMPS.
