This course focuses on the high-voltage controller (HVC) isolated DC/DC and its roadmap, starting with the topology of isolated DC/DC power applications. It also provides an overview of the current GP PWM controller 300mm wafers, an introduction to the existing GP PWM from TI, an introduction to the differences of the "UCC28C5x-Q1", the differences between different models, and an introduction using real examples and data. What are the advantages of using the UCC14XXX-Q1, the importance of integrated transformers, and how the footprint of the integrated transformer differs from that of today with the use of real circuits. And provides real-world examples to compare and explain the benefits and differences, explaining the " UCC12040 " & " UCC12050 "The industry's smallest and lightest isolated bias power module With power of up to 0.5W, this chip has the advantages and can be used in those scenarios, given the highest noise immunity and low EMI.
