【应用】N沟道超级沟槽功率MOSFET HMS4488 MOSFET用于快速充电桩,RDS典型值57mΩ
简述
近年来,新能源汽车快速普及,这种新型的低碳出行交通工具一经问世,就引起了人们极大的兴趣,相较于传统燃油汽车,新能源汽车动力强劲,用车成本低,唯一的缺点就是续航里程稍显不足,部分纯电的新能源车标称续航只有一百多公里。为了可以满足新能源车快速充电的目的,快充桩应运而生,部分充电桩可以实现在半小时内将电量充至80%,极大地缓解了人们的续航焦虑。对于快充桩来说,其中的开关电源模块十分关键,而MOSFET元件做为开关电源的核心器件显得尤为重要。
挑战
客户作为行业著名的的快充桩开关电源生产商,一直以产品质量稳定可靠,功耗低,响应速度快著称。今年,客户正在研发新的快速充电桩开关电源产品,做为关键器件的MOSFET的选型显得极其重要。如何选择到一款功耗低,结电容低,响应速度快的产品是研发人员需要重点考虑的课题。
解决方案
了解到客户的需求后,虹美公司技术团队与客户进行多次交流和沟通,经过反复评估,最终推荐客户选用型号为HMS4488的N沟道超级沟槽功率MOSFET。
HMS4488采用了先进的超级沟槽工艺,对应的VDS =150V,ID =5A,当VGS=10V时,RDS(ON)典型值=57mΩ。开关电源模块在工作时,部分功耗损失在MOSFET的内阻上,同时也会导致MOSFET温度上升,影响整个器件的工作效率。客户之前生产的开关电源产品中,由于选择的MOSFET对应的RDS值较大,导致一部分功率消耗在内阻上,使实际的功耗转换率相对较低,而HMS4488的RDS典型值只有57mΩ,非常适合客户正在研发的新开关电源产品,经客户测试验证,装配有HMS4488型MOSFET的开关电源产品相较上一代产品,功耗减低20%以上。
HMS4488反向传输电容(Crss,在VDS=50V,VGS=0V, F=1.0MHz情况下)仅为17.8PF。反向传输电容越小,导通时漏源电压VDS的下降时间越短,关断时漏源电压VDS的上升时间越短,相应的功率损耗越小,这就意味着MOSFET可以以更短的时间执行通断,响应速度可以更快。客户在之前的产品选型中选择了结电容较大的MOSFET,样品装机完成后送至主机厂配套测试,无法满足主机厂的快速响应需求。而选用HMS4488型的MOSFET以极低的结电容性能,相比之前产品提升了30%的快速响应时间。客户重新选择HMS4488装机,一次性通过了主机厂的测试。
此外,HMS4488采用无铅镀层,SOP-8标准的封装形式,可以满足正常的贴片生产。
成果与收益
HMS4488为N沟道MOSFET,具有功耗低,结电容低,响应速度快等特点,完全满足客户新的快充桩开关电源的设计需求,提升了快充桩开关电源的功耗表现和性能表现,提升了了客户产品的市场竞争力。
