TPS54061: Max Duty cycle and allowable output voltage range for TPS54061

Part Number: TPS54061

Dear Colleagues,

I'm revising a design based on the TPS54061. What are the allowable output voltage range and maximum duty cycle? I cant find these on the datasheet.

    Carlos,

    You are right . I dont see any Min off time specs in the datasheet(has typical min on time specs only ) . I will try to dig in and find more on duty cycle constraint. May i know the requirement you are looking at . Also there are many newer generation devices which have detailed specs on Min on and off time . We can take this offline over email .

    I would like to keep this one for a re-spin of TIDA-00285.

    Vin = 15-50V

    Vout = 12V @ 100mA

    Seems like the parametric search tool has some specs, are these accurate?

    This table did not specify which frequency it could provide 58V Vout max. I don't think we can derive the Toff min from this table. I used Webench to run your design spec with this device. Webench provided a design. I think it should be fine if Webench is ok with it. Please try a Webench design.
