Description

The LM5574 evaluation board is designed to provide the design engineer with a fully functional power converter based on Emulated Current Mode Control to evaluate the LM5574 regulator IC. The evaluation board provides a 5V output with a 0.5A current capability. The ultra-wide input voltage ranges from 7V to 75V. The design operates at 300kHz, a good compromise between conversion efficiency and solution size. The printed circuit board consists of 2 layers of 2 ounce copper on FR4 material with a thickness of 0.06 inches. This application note contains the evaluation board schematic, Bill-of-Materials (BOM) and a quick setup procedure. Refer to the LM5574 datasheet for complete circuit design information.
