LM20242EVAL

36V，2A PowerWise® 可调节频率同步降压稳压器评估模块

LM20242EVAL

概述

The LM20242 synchronous rectifier Buck evaluation board is designed to provide the design engineer with a fully functional Buck power converter based on Current Mode Control to evaluate the LM20242 switching regulator IC. The evaluation board provides a 3.3V output with 2A current capability. The input voltage ranges from 8V to 36V. The design operates at 300 kHz, 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 0.062 inches. This application note contains the evaluation board schematic, Bill-of-Materials (BOM) and a quick setup procedure. Refer to the LM20242 datasheet for complete circuit design information.
