Dear sir,
I am working on lm5116 buck converter. This IC have two types supply vccx & vcc. Where vccx is external supply & vcc is internal supply. My question is that When we are using Vccx supply at maximum input voltage then output have a fluctuation & seems as circuit not ON properly. While when we are using vcc then circuit on properly at all input range. So how can circuit work properly at all input range from vccx supply.
