Single Cable and Connector Bode Diagrams and Step-Load Adapter for DC/DC Bode Measurements

by Christian Kück - Monolithic Power Systems

A single LAN cable adapter connects the DC-DC converter with the Bode 100 measurement. This enables easy and robust test setups on the bench and in thermal chambers. A simple LAN patch cable is the only connection needed. Bode measurement performance, schematics and layout of the system is shown. In addition step load tests with an active step load on the DUT test adapter can be conducted. Good engineering practice of DC-DC loop compensation using Bode and step load measurements will be shown.
