LM3481SEPICEVAL
概述
The LM3481 SEPIC evaluation board is designed to provide the design engineer with a fully functional power converter solution with two output voltage options. It produces a selectable output voltage of 12 V at 1.25A or 5V at 3A. The switching frequency for the converter is set to 500 kHz. The printed circuit board consists of 2 layers of FR4 material with 2 ounce copper on both layers. This application note contains the evaluation board schematics, Bill-of-Materials (BOM) and a quick setup procedure. Refer to the LM3481 datasheet for complete circuit design information.
