【应用】导通阻抗20Ω的家电用电源管理芯片KP36572用于微波炉,实现可闻噪音消除
自主可控的本地化供应链正在各行各业不断推进,这为国内集成电路企业带来了难得的国产替代黄金时期。 家电产品作为日常生活的必需品,使用量较大且产品单价较高,在其研发过程中特别注重器件的易用性、稳定性和可靠性;同时由于家电产品的功能和品质要求不断提升,也存在着器件性能升级的需求。
作为整个家电系统的核心部件,家电用电源管理芯片之前基本被欧美半导体公司所垄断。加上现有方案不仅成本高且更新换代慢,影响了国产家电行业的快速发展。
作为致力于成为行业领先者的国产半导体芯片企业,必易微不仅着眼于国产替代解决供应紧缺的问题,同时力争用技术创新实现国产产品的性能升级。本文将向大家介绍一款微波炉里典型美商电源方案的替代案例。
2020年全国微波炉的总产量约9000万台,2021年预计将增长5%以上,而据不完全统计,其中接近80%使用了美商一款型号为XXX364的ACDC电源芯片。
XXX364之所以使用如此广泛,通过对比传统方案可以看到其优势在于设计简单:
传统方案
XXX364的优势
1.无需辅助绕组供电,支持变压器采用双绕组设计。
2.无需启动电阻,集成高压启动。
3.无需采样电阻,集成原边电流采样。
4.无需副边TL431控制,支持副边稳压管恒压输出。
XXX364的不足
由于XXX364采用ON/OFF控制带来了频率控制不稳定,导致XXX364工作时始终存在可闻噪声,终端厂家需要采用变压器点胶、含浸等手段,以缓解整机系统噪音,但是重载伴随的噪音仍旧无法有效消除。
本期隆重向大家介绍必易微家电电源管理芯片新成员——高性能、低成本离线式电流模式PWM控制功率开关KP36572。此产品脚位兼容美商XXX364,其外围线路简洁程度与竞品完全相同,除此之外有了更多的亮点。
亮点1——消除可闻噪音
KP36572采用了根据FB电压线性调节的降频技术,相比于ON/OFF控制,此技术可以平滑的调节开关频率而无异音产生。从实测样机的数据表明,线性降频控制较ON-OFF控制可以降低近5-10分贝噪音(分贝仪紧贴样机测得)。
KP36572工作频率稳定
XXX364工作频率不稳定
亮点2——低温升,高效率
KP36572的内置700V MOSFET导通阻抗较XXX364低近17%,导通损耗更低,效率更高,工作中芯片的温升更低,整机工作可靠性更高。
亮点3——EMC表现优
通过特有的EMI调节技术,KP36572可以实现传导AV平均量的有效分散,从而显著提升传导AV裕量,降低EMC设计成本。
亮点4——HBM ESD良好
KP36572 ESD HBM已达到4.5kV,处于国内领先水平;良好的ESD性能可以保证系统高可靠性的持续工作。
此外,KP36572在输出电压调整率、输出电压纹波、动态响应等性能指标上与XXX364一致。
小结
KP36572作为必易微家电产品线新成员,以快速解决家电企业本地化供应,保证品质和可靠性为首任,同时大幅提升了电源模块的整体性能表现(噪声、EMC、温升和ESD等),与XXX364性能对标。
随着国产替代的加速和家电性能高端化的演变,必易微将始终坚持 “独特创新,易于使用”的理念,陆续推出一系列高可靠性、具有显著特色的家电产品,以专注凝聚技术、以匠心回馈信任,力争为客户带来更好的产品体验。
