【选型】替代TI TLV70450DBVR的高压线性稳压器SGM2203-5.0YN5G/TR,具有36V更高输入电压
圣邦微推出的高压线性稳压器SGM2203-5.0YN5G/TR,具有36V输入电压,产品设计兼容性更强。某客户的摄像头产品中采用了TI的TLV70450DBVR给MCU供电,但输入电压最高只有24V,试验时出现耐压不足的问题,笔者向客户推荐了SGM2203-5.0YN5G/TR。二者性能参数对比如下图所示。
图1 SGM2203-5.0YN5G/TR与TLV70450DBVR性能参数对比
通过上图易知:
1、SGM2203-5.0YN5G/TR具有更高输入电压,产品设计兼容性更强;更低电压降有利于提高转换效率,降低功耗;优秀的负载调整率,在输入电压值及负载电流值变化相同时,输出电压变化更小,使得负载工作更加稳定。
2、TLV70450DBVR在静态电流和输出电压精度方面表现的更好,不过在一般应用中,SGM2203-5.0YN5G/TR可以满足要求。
SGM2203-5.0YN5G/TR与TLV70450DBVR的封装均为SOT-23-5,二者的引脚定义如下图所示。
图2 SGM2203-5.0YN5G/TR与TLV70450DBVR引脚定义图
通过上图易知:
二者引脚定义一致,可实现兼容设计,在电路设计时无需改版,可以完美实现替换。
总结
通过上述对比,SGM2203-5.0YN5G/TR性能参数相对更优,且是国产器件,具有更低的成本和更好的供货周期,可快速支持样品和后续量产服务,因此,推荐客户使用SGM2203-5.0YN5G/TR替代TLV70450DBVR进行设计。
