TPS61088的补偿电路参数计算

Other Parts Discussed in Thread: TPS61088

请问TPS61088的补偿电路中计算补偿电容时fc是如何计算的。如果输出电容是并联,ESR值如何计算。EN高电平可以是12v吗?请您赐教。

      穿越频率fc是选取的:

       It is generally accepted that the loop gain cross over no higher than the lower of either 1/10 of the switching frequency,

       输出电容ESR,需要看输出电容的规格书,然后按照电容并联计算(类似电阻并联,但是ESR要在电容datasheet上查询)。

      EN最高7V,不可以12V.
