【选型】国产DCDC转换器SGM61410可P2P替换杰华特JW5018,待机电流仅14μA
随着物联网的普及,家居智能化成为了一种趋势,智能的无线开关越来越多地取代传统的机械开关。某客户开发的一款智能开关采用单火线的方案,开关内部只有预留火线,由于后级的DCDC转换器 JW5018待机功耗比较高,容易导致 “鬼火”现象,所以本文推荐用圣邦微电子的SGM61410来替代。
图1:单火线智能开关
图2:SGM61410与JW5018参数对比图
从上面表格中的参数我们可以得知:
1、基本上的电流电压参数基本一致,工作温度范围完全一致;
2、SGM61410和JW5018都采用峰值电流模式,SGM61410在轻载时支持PFM模式,可以有效地提高轻载时的工作效率,最高的效率达到了95%;
3、SGM61410的静态电流只有14μA,大大降压了整个系统的功耗,可有效地避免“鬼火”现象的出现。
图3:SGM61410(左)与JW5018(右)封装管脚顺序对比
图4:SGM61410(左)与JW5018(右)应用电路图对比
从图3和图4可以看出,SGM61410和JW5018的封装和管脚定义完全一致,使得在进行物料替换的时候,不需要重新设计PCB,缩短了更换物料时的周期。同时,两个芯片的VFB电压值都是800mA,就不需要修改外部的反馈电阻值,使得在外围器件使用上也可以达成高度的一致。
