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
