Low EMI Layout Made SIMPLE With LM43600/1/2/3 and LM46000/1/2 (Rev. A)

Texas Instruments

Published Date: 09/12/2014

Description

Printed Circuit Board (PCB) layout for Switched Mode Power Supplies (SMPS) is critical to achieve proper converter operation good thermal performance and excellent radiated EMI performance. Optimized board layout for low radiated EMI is made very simple by the package and pin arrangement of the SIMPLE SWITCHER ® Synchronous Buck Converter family LM4360x and LM4600x
