LM25137-Q1 Synchronous Buck Controllers

Texas Instruments LM25137-Q1 Synchronous Buck Controller is a 42V synchronous buck DC-DC controller with three options for functional safety (capable, ASIL B, and ASIL D). The device uses an interleaved, stackable, peak current-mode architecture for fast transient response, easy loop compensation, excellent line and load regulation, and accurate current sharing with paralleled phases for high output current. A high-side switch with a minimum on-time of 22ns facilitates large step-down ratios. This feature enables the direct conversion from 12V and 24V automotive inputs to low-voltage rails for reduced system design cost and complexity. The LM25137-Q1 continues to operate during input voltage dips as low as 4V, at 100% duty cycle if needed. The operating run-time in battery-powered automotive systems is extended by a 9µA no-load quiescent current with the output voltage in regulation.
