Quick stability check of DC/DC converters using the Richtek Load Transient Tool Kit

Finish your power design in 4 simple steps:

The Richtek Load Transient Tool makes DC/DC converter stability check simpler and faster than before! No matter your design is a Buck or Boost converter, a linear regulator or even a LED driver, this unique fast load transient tool kit will help you identify loop stability problems and estimate the converter control loop bandwidth to judge the correct control loop compensation.

In this tutorial video, you will find:

An introduction to the Richtek load transient tool kit.
Measurement examples of converter fast step response: Learn about the relation between converter step response shape and the control loop phase margin.
Tips on how to do stability test: How to set the output current static load and dynamic load?
An example of a stability test using RT7297C current mode Buck converter: How to estimate the converter control loop bandwidth from converter transient response time, and compare load transient test result with actual open loop gain-phase measurement using a network analyzer.
An example of a stability problem: See the influence of reduced output capacitor value on the converter stability and control bandwidth, and learn how to modify your design to get stable performance again using the load transient tool.
