TPS61131 Ramp Rate Question

Joe Howard

Other Parts Discussed in Thread: TPS61131

I am currently looking at the TPS61131 for a customer that needs a DC/DC converter that will have a controlled ramp rate with near zero load from 0V to 3.3V in more than 1ms to less than 200ms.

Does this product meet this specification?

It meets all the other requirements the customer has given.

Any help would be most appreciated!

Thanks!

Joe

    I found this App Note about Extending the Soft Start Time in the TPS6107x Family of

    Boost Converters on the product page of the TPS611311.

     

    Inside the conclusion of the App Note, it reads:

     

    “…This basic circuit is applicable in principal to any TPS6xxxx device. Checking the load regulation and control loop stability

    should be done to assess its applicability to specific devices besides the TPS6107x family.”

     

    With the help of this app note, you can adjust the soft start time (ramp rate) to fall within this range.
