LM5143-Q1
AEC-Q100 Grade 165V dual-channel synchronous buck controller
Uses external MOSFETs and inductors for dual outputs or a multiphase rail. It is not an integrated 40A module: current capability, thermals and transient margins depend on the complete power stage.

AEC-Q100 Grade 1External dual-MOSFET ideal-diode and power-path controller
Uses external back-to-back N-channel MOSFETs for reverse-polarity protection, reverse-current blocking and load disconnect rather than carrying load current inside the IC. LM7480-Q1 is the family name for 00/01: 00 combines linear forward-drop regulation with a comparator, while 01 is comparator-only. The 10.5mV regulation specification is not shared by both.

AEC-Q100 Grade 13.8–36V, 3A synchronous buck converter
A 3A buck with integrated switches, compensation and power-good signaling for automotive load rails. Frequency depends on the variant; 400kHz, 1.4MHz and 2.1MHz are not an arbitrary runtime menu for every OPN.

AEC-Q100 Grade 1Four-buck configurable multiphase PMIC
Four buck cores can form a single four-phase rail or multiple outputs for processor power. Unlike TPS6594-Q1 it has no four-LDO block; verify exact-OPN NVM, interface and sequencing instead of assuming a drop-in replacement.
