TPS54310电源要输出1.4V,反馈网络要如何匹配

Other Parts Discussed in Thread: TPS54310, TPS62130

     各位大神,小弟有个苦恼很久的问题想请教给位。

     最近由于项目需要,要用TPS54310芯片配成5V输入,1.4V输出的电源。按照芯片手册能很快依据确定输出电容,但如何配置整个反馈网络我一直没头绪,在网上查了资料,发现各种电容、电阻值得都有。在此想请教大家,如何选择合适的反馈网络电容和电感值?

  

          依据芯片手册,计算出确定输出电压的R2=10.7KΩ,R4=18.7KΩ。请问R3、R5、C7、C8、C9该如何选择?
