3 Description
The LM5143A-Q1 is a 65-V DC/DC synchronous
buck controller for high-current single or dual outputs.
Deriving from a family of wide-VIN range controllers,
the device uses an interleaved, stackable, peak
current-mode control architecture for easy loop
compensation, fast transient response, excellent load
and line regulation, and accurate current sharing with
paralleled phases for higher output current. A highside
switch minimum on time of 65 ns provides large
step-down ratios, enabling the direct conversion from
12-V, 24-V, or 48-V inputs to low-voltage rails for
reduced system complexity and cost. The LM5143AQ1
continues to operate during input voltage dips as
low as 3.5 V, at nearly 100 duty cycle if needed.
The 15-μA no-load quiescent current with the
output voltage in regulation extends operating runtime
in battery-powered automotive systems. Power
the LM5143A-Q1 from the output of the switching
regulator or another available source for even lower
input quiescent current and power loss.
