Introduction

The LM5116-12 evaluation board is designed to provide the design engineer with a fully functional power

converter based on Emulated Current Mode Control to evaluate the LM5116 controller IC. The evaluation

board provides a 12V output with a 5A current capability. The operating input voltage ranges from 15V to

80V. The design operates at 250kHz, a good compromise between conversion efficiency and solution

size. The printed circuit board consists of 4 layers, 2 ounce copper top and bottom, 1 ounce copper

internal layers on FR4 material with a thickness of 0.06 inches. This user's guide contains the evaluation

board schematic, Bill-of-Materials (BOM), and a quick setup procedure. For complete circuit design

information, see LM5116 Wide Range Synchronous Buck Controller (SNVS499).

• Input Range: 15V to 80V

• Output Voltage: 12V

• Output Current: 0 to 5A

• Frequency of Operation: 250 kHz

• Board Size: 2.55 × 2.65 × 0.7 inches

• Load Regulation: 1

• Line Regulation: 0.1

• Hiccup Mode Current Limit Protection
