Original question:

UC1875: Is there any type of chip that can support a 1800V sine convert to a 300V？

UC3872: Can UC3872 implement the Ballast application ?

Part Number: UC3872

Tool/software:

Generate a 1800V sine wave during startup, with a small current and a duration of approximately 10ms; Next, immediately convert to a 300V, 10A sine wave and maintain it continuously.

Can UC3872 implement this application? How should transformers be modified? What should be noted in feedback and loop design?

    Hi Tom,

    This chip is old and not developed by our current team. Please give me some time to investigate it and check whether it fits your application conditions. I will get back to you within two weeks. Thanks for your understanding.

    Best Regards,

    Steven
