TIDM-02002: How do we deal with steady state at no load?

Part Number: TIDM-02002

Champs,

I am asking this for our customer.

In our design, did we test the performance at no load, which is one of the challenges for LLC control?

What is the efficiency, output ripple at no load?

Do we only use frequency control or have another control mode?

OR do we have any method to deal with it except just switching at very high frequency?

  • Hello,
    Concerned experts have been notified of this query.
    Note that it is US Spring Holiday today and most of the TI engineers are away.
    Please expect a delayed response, surely by early next week.

    TIDM-02002 is connected to a battery charger and hence no load conditions is not possible. Light load is possible. We have not yet done tests at very light load.

    Burst mode is a common technique used but we have not implemented this on this design.

    I see.
    Thank you for your information anyway.
