User's Guide SNVA298A–November 2007–Revised April 2013 AN-1748 LM5005 Evaluation Board 1 Introduction The LM5005 evaluation board is designed to provide the design engineer with a fully functional power converter based on emulated current mode control to evaluate the LM5005 regulator IC. The evaluation board provides a 5 V output with a 2.5A current capability. The ultra-wide input voltage ranges from 7 V to 75 V. The design operates at 300 kHz, a good compromise between conversion efficiency and solution size. The printed circuit board (PCB) consists of 2 layers of 2 ounce copper on FR4 material with a thickness of 0.06 inches. This document contains the evaluation board schematic, Bill-of-Materials (BOM) and a quick setup procedure. For complete circuit design information, see the LM5005 High Voltage 2.5 Amp Buck Regulator Data Sheet (SNVS397). The performance of the evaluation board is as follows: Input Range: 7 to 75 V Output Voltage: 5 V Output Current: 0 to 2.5A Frequency of Operation: 300 KHz Board Size: 2.75 X 1 X 0.4 inches Load Regulation: 1% Line Regulation: 0.1% Over Current Limiting 2 Evaluation Board Schematic Figure 1.
