SNVA790A October 2020 – July 2022 LMR36520
The purpose of this application note is to lead the reader through the design of an isolated buck also known as a Fly-Buck? converter using the LMR36520 from Texas Instruments. This application note will describe the typical operation of a Fly-Buck? converter from a theoretical perspective, and then walk through the process of Fly-Buck? converter design from a set of given operating conditions using design equations derived in referenced reports. Physical measurements will be compared to expected results, and design limitations will also be discussed.
