Other Parts Discussed in Thread: TPS40050, TPS40051, TPS40053, TPS40057, TPS40060, TPS40061, TPS40054, TPS40055

Dear All ,

I am in need of a new design  with the following specifications for automotive application,  

Vin (min) = 18 V, Vin (max) = 36 V,  Vout = 14V , I out = 10 A ,  AEC Qualified, Automotive application ,

As per the the  automotive selection guide from TI i can use  TPS4005X

I would  like to use Switcher pro But  As per My knowledge Switcher Pro cant support TPS4005X-Q1  devices..

Any recommendations on this is Highly appreciable

    VSC,

    You can use the base TPS4005x devices in Switcher Pro.  It will have similar performance to the TPS4005x-Q1 device, with the same design equations.

    You may have some difficulty finding Automotive Qualified components in Switcher Pro, since that tool was not developed with Automotive Qualification in mind.

    Thanks a lot Peter for your Prompt reply . 

    As per my  knowledge  the  AEC qualified devices  which matches with our spec are are  TPS40050 , TPS40051, TPS40053, TPS40057 .

    But  TPS40050 , TPS40051, TPS40053 are not found in Switcher pro.

    Due to some Specific reasons the part number we are considering are   TPS40050  and TPS40060( though not Q1) .

    Both devices are not found in Switcher Pro .

     Is it possible use switcher Pro  for this devices   ?And if yes how ?

    The TPS40050 and TPS40060 controllers are source only (diode emulation) versions of the TPS40051 and TPS40061 controllers.

    The TPS40051 isn't modeled in Switcher Pro because it has been Not Recommended for New Designs prior to its integration into the Switcher Pro tool.  The TPS40050 has been replaced with the TPS40054 controller.  The TPS40054 (diode emulation) controller should be designed in Switcher Pro using the TPS40055 (fully synchronous) controller model.

     

    I don't think the TPS40061 is available in Switcher Pro, but if it is, it can be used to design a TPS40060 based converter.
