向工业级看齐的原边反馈满足六级能效标准的AC/DC电源控制芯片方案
微盟电子发布的ME8329-N是一款满足六级能效标准原边反馈准谐振模式的AC/DC电源控制芯片。内部集成了高压功率MOS管,可用于充电器,适配器和LED驱动等领域。可实现±5%的恒压恒流精度和小于60mW 的待机功耗。在恒压模式下内置了线电压补偿功能。采用了准谐振控制,实现高效率和良好的EMI性能,满足六级能效标准要求。
该芯片集成了诸多保护功能,包括:VDD欠压保护(UVLO),VDD过压保护(OVP),软启动,逐周期过流保护,所有管脚浮空保护,内置前沿消隐,VDD电压钳位保护,过温保护等。
目前ME832X-N产品区别列表如下:
现以显示器电源ME8329AS7G-N 19W输出的系统方案为例作如下介绍。

19V/1A的样机实物图
注意:在满足功能要求的情况下,
①19W输出时排脚散热的铜箔面积尽量大于230mm2@1盎司厚度,并且散热铜箔要开窗上锡,对同一个IC功率越大散热铜箔的面积相应越大。
②由于结构限制或其他原因,排脚散热的铜箔面积过小时,该芯片应降功率使用。
③根据输出线长短,如果大于50cm,输出端尽量加小共模或用带磁环的输出线,视EMC情况及成本综合考虑。
变压器参数
样机温升实测数据
样机效率及待机功率测试
样机EMC测试
通过以上分析该AC/DC电源控制芯片易过六级能效,温升OK,易过EMC。

南芯半导体强势切入便携式储能市场,实现国产电源和电池管理类芯片全场景覆盖
本文主要介绍南芯的多款产品应用方案在便携式储能电源产品上的应用,并给于了应用方案和方案应用优势
模拟电源的春天要等到2026年?
模拟电源是电路中的基础器件,也是功能电路不可或缺的一部分,因此被称为行业的晴雨表,也更容易受到终端行业景气度的影响。目前,国产模拟电源器件厂商还在快速成长期,产品丰富度和TI、ADI等厂商还有着很大的差距,这也导致同一行业周期下,各家厂商的悲喜并不相通。但随着整合并购和末位淘汰,最终国产模拟电源厂商的感受会逐步向TI靠拢。
