【应用】汽车级表面贴装电感具有磁屏蔽,适用于DC/DC变换器
DC-DC变换器是一种可以在直流电路中将电压值对应电能进行转换的装置,利用电容/电感的储能的特性,通过可控开关(MOSFET等)进行高频开关的动作,将输入的电能储存在电容/电感,当开关断开时,电能再释放给负载。由于具有设计周期短、可靠性高以及系统升级容易等优势,被广泛应用于汽车电子领域,作为辅助电源的核心部件。
图1 DC-DC变换器在汽车中的应用
电感式DC-DC变换器是通过电感不断的储能/放电,最后达到稳定电压/电流输出。但是,随着开关的打开与闭合,升压电感器会经历电流纹波,而纹波电流一般需要低于平均电感电流的20%。因此,电感器的选取至关重要:当电感过大时,则会要求大得多的电感器;当电感太小时,则会引起更大的开关电流,尤其是在输出电容器中,而这又需要更大的电容器。
作为一家全球性的工程电子设备供应商,TT Electronics面向汽车级应用推出了HM73E-10系列表面贴装电感器,通过AEC-Q200认证,电感典型值范围为0.19uH~3.76uH(100kHz,0.1V),额定电流15A~65A,采用密封结构。同时,采用磁屏蔽,可以最大化电感值和高饱和电流。目前,提供六种型号(HM73E-10R22LFTR、HM73E-10R47LFTR、 HM73E-101R0LFTR、HM73E-101R5LFTR、HM73E-103R3LFTR、HM73E-104R7LFTR )可选,能够在-50℃~+155℃的温度范围内正常工作,具有极高的可靠性和稳定性。
与同类产品相比,该系列的直流电阻更低,温升性能更好,具备更卓越的性能。其中,HM73E-104R7LFTR 的电感值高达3.76uH,HM73E-10R22LFTR的额定电流可高达65A,完全满足汽车应用所需的高性能和可靠性需求。同时,该系列的尺寸仅为11.5mmx10.5mmx5.9mm,非常适用于对尺寸要求高的汽车级DC-DC变换器。
此外,HM73E-10系列表面贴装电感器符合RoHS标准,除了可用于汽车动力传动系统、发动机和变速箱控制系统、混合动力电动汽车、启停系统以及电动转向等应用,还可用于包括开关电源以及自动化系统在内的工业应用。
