More Information
The LM25143-Q1 is a 42-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 high-side switch minimum on time of 65 ns provides large step-down ratios, enabling the direct conversion from 12-V or 24-V automotive inputs to low-voltage rails for reduced system complexity and cost. The LM25143-Q1 continues to operate during input voltage dips as low as 3.5 V, at nearly 100% duty cycle if needed.
