【选型】洺太降压DCDC SK6693可兼容SY8113,助力机顶盒设计
在机顶盒产品设计中,一级电源一般需要将DC12V转5V给后级供电,市面上很多厂家会选择Silergy的SY8113。随着近两年芯片市场供货紧张问题日益突出,本文推荐上海洺太电子一款降压DCDC SK6693,为用户在选型时提供备选方案。
如下为两者主要电性能参数对比:
图1: SK6693与SY8113主要电性能参数对比
1、通过上述对比可知两者电性能参数基本一致,除上述电性能外,SK6693和SY8113均内置多种保护方式,如过流、过温保护等,为芯片可靠性提供保障;
2、SK6693和SY8113封装均为SOT23-6,并且引脚定义顺序完全相同,在进行实际设计时,可直接兼容互换,大大缩短研发验证周期。
如下图2为两者封装pin脚定义和典型应用电路对比:
