Automotive High Current, Wide VIN Synchronous Buck Controller Reference Design Featuring LM5140-Q1

Overview

TopologyBuck Converter
Input voltage5.5-42 V
Output 15 V / 45 A
IC revisionA

Description

PMP15032 demonstrates the operation and performance of the LM5140-Q1 synchronous buck controller in a high current dual-phase application. The PMP15032 operates over the input voltage range of 5.5 to 42V. The EVM provides a 5.0V output with a maximum load current of 45A (22.5A per phase). The LM5140-Q1 switching frequency is set to 440 kHz to minimize switching losses and obtain maximum efficiency.
