The LM5143 is a 65-V DC/DC synchronous buck controller for high-current single or dual outputs.
Deriving from a family of wide-VIN range controllers, 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 provides large step-down ratios, enabling the direct conversion from 12-V, 24-V, or 48-V inputs to low-voltage rails for reduced system complexity and cost.
