I am designing a Floating Buck converter(Power Switch connected in negative DC input side, positive rail directly connected to the battery) for 52V/15A Battery Charger using UC2843, Battery Should charge at 15A in CC Mode until the battery voltage reaches around 51V.
Based on the application note given here https://www.ti.com/lit/ug/tidu413a/tidu413a.pdf?ts=1606830361321&ref_url=https%253A%252F%252Fwww.google.com%252F
The inductor current is not constant when the duty ratio is above 0.5. the slop compensation designed based on the UC2843 datasheet. please help me out solving the problem.
