客户的项目是直流无刷电机控制板,需要内置高耐压功率管的同步降压芯片来设计供电模块,客户的需求是:输入电压要在55V以上,输出电流要在2A以上,工作温度在-40℃-150℃,想要TO-263封装的。这里推荐国产厂牌华冠半导体的一款中高压DCDC同步降压芯片LM2576HV系列。


它的特点是:

  • 输入电压高达60V

  • 输出电流高达3A

  • 有固定输出3.3V、5V、12V、15V型号和可调输出电压型号

  • 工作频率52kHZ

  • 具有热关断过流限制等保护


LM2576HV的优势:

  • 外围电路非常简单,只需要四个外部器件,便于设计

  • 供货交期很有优势

  • 价格很有优势


LM2576HV支持多种封装:TO-220、TO-263、SOP-8。本方案中客户选择的封装TO-263如图所示:

LM2576HV的典型应用电路如图所示:
