LMQ64480-Q1: integrated capacitors

Part Number: LMQ64480-Q1
Other Parts Discussed in Thread: LMQ644A2-Q1

LMQ64480-Q1的EMI特征具有integrated capaticors(集成电容)这一功能,LMQ644A2-Q1没有这一功能,但数据手册里面应用典型场景的原理图这两个一模一样,没有看出integrated capaticors这个作用在哪?有人可以帮忙解答一下吗?

  • 您好,

    您说的这两个器件共用一个数据手册,请查看数据手册第一页,www.ti.com/.../lmq644a2-q1.pdf

    The LMQ644xx-Q1 incorporates spread spectrum in an optimized enhanced HotRod QFN package, with wettable flanks, and four 22nF high frequency integrated capacitors to minimize EMI.

    器件的不同之处请参考数据手册第三页的表格,

    您是看到LMQ644A2-Q1主页上没有integrated capaticors功能是吧?但是综合数据手册来看,很有可能是主页漏写了这个功能。
