Introduction
The LM5001 evaluation board is designed to provide the design engineer with a fully functional isolated
flyback power converter based on current mode control to evaluate the LM5001 switching regulator IC.
The evaluation board provides a 5V output with 1A current capability. The input voltage ranges from 16V
to 42V. The design operates at 250kHz, a good compromise between conversion efficiency and solution
size. The printed circuit board consists of two layers of two ounce copper on FR4 material with a thickness
of 0.062 inches. This application note contains the evaluation board schematic, Bill-of-Materials (BOM)
and a quick setup procedure.
