3 Description

The LM5137F-Q1 is an 80V dual-channel buck

controller offered frrom a family with three options for

functional safety: Capable, ASIL B, or ASIL D. The

device uses an interleaved, stackable, peak currentmode

architecture for easy loop compensation, fast

transient response, excellent load and line regulation,

and accurate current sharing with paralleled phases

for high output current. A high-side switch minimum

on-time of 15ns facilitates large step-down ratios,

enabling the direct conversion from 12V, 24V or 48V

automotive inputs to low-voltage rails for reduced

system design cost and complexity. The LM5137F-Q1

continues operating during input voltage dips as low

as 4V, at 100% duty cycle if needed.
