Automotive High Current, Wide VIN Synchronous Buck Controller Reference Design Featuring LM5140-Q1
Overview
| Topology | Buck Converter |
| Input voltage | 5.5-42 V |
| Output 1 | 5 V / 45 A |
| IC revision | A |
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.
Features
