Output Ripple Measurement Methods 03707 Rev AApplication Note Accurate Output Ripple Measurement Methods for Enpirion Products
Summary:
This application note provides a brief tutorial on output voltage ripple and describes methods for accurately measuring the output voltage ripple on an Enpirion converter. This paper explains the proper measurement setups using standard as well as specialized lab equipment. Sample measurements will also be provided illustrating the differences between each technique.

Introduction
All of Enpirion products produce very small output ripple when PCB layout and component choice guidelines are followed. The one question customers often ask is, “How do I accurately measure low output voltage ripple?” Customers often measure the ripple using traditional methods developed for power supplies with large output
