This reference design is for an automotive display application with a customized form factor. The design demonstrates the excellent thermal performance of LM61460-Q1 with its HotRod™ QFN package as well as the low EMI aided by its spread spectrum feature. It generates four 5-V/3.3-V/1.1-V/1.8-V rails. It is designed for high efficiency and low noise applications where thermal performance and EMI performance are needed.
