The LM5143-Q1 is a 65-V synchronous buck DC/DC controller for high-current single or dual outputs.
The device uses an interleaved, stackable, peak current-mode control architecture for easy loop compensation, fast transient response, excellent load and line regulation, and accurate current sharing with paralleled phases for higher output current.
A highside switch minimum on-time of 65 ns gives large step-down
