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.
