3 Description

The LM5137-Q1 is an 80V synchronous buck DC/DC

controller offered from 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 lowvoltage

rails for reduced system design cost and

complexity. The LM5137-Q1 continues to operate

during input voltage dips as low as 4V, at 100% duty

cycle if needed. The 12.7μA no-load quiescent current

with the output voltage in regulation extends operating

run-time in battery-powered automotive systems.
