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.
