TPS62161: IC's are compliance with Automotive standards(AEC-Q100) or not

Part Number: TPS62161
Other Parts Discussed in Thread: TPS62160, , TPS61253A, TPS62293-Q1

Dear TI,

Can you please confirm whether the Two Ic's are compliance with Automotive standards.If not could you suggest an alternative with automotive grade.We need 1.8V fixed output with 3V3 input supply.

In TPS62160 IC, could you please explain why VOS and FB pins are needed to control the Output stability? Please elaborate the VOS direct and compensation control and FB pin functions in block diagram (Page 07/35 ).

Thanks,

Dayanand

  • Dear Dayanand,

    Welcome to the forum. The 2 devices you found will meet your specification, but they are not automotive qualified. Automotive qualified devices usually have -Q1 at the end of the part number. Currently, there is an automotive qualified version of TPS62160, but not for TPS62161.

    You may even find more suitable devices for your requirements if you search for automotive qualified Buck Converters for 3.3V to 1.8V conversion.

    In the product folder of TPS62160 there is a link to an appliation note describing in more detail how the control topology (DCS) is working.

  • Dear Juergen,

    Thanks for your reply. I did search but not found the required IC. Need 1.8V fixed buck regulator(Not programmable), >800mA current capable with Automotive grade. Please suggest if any.

    Can you also confirm whether TPS61253A is qualified with Automotive grade.In TI products filter, this component is under Automotive grade but in datasheet has not mentioned as Automotive. If not please let us know does this IC has Automotive version.

    Thanks and Regards,
    Dayanand
  • I did not find an automotive version of TPS61253A, but this is not a buck regulator either.
    For 3.3V input and 1.8V fixed output voltage at 0.8A I would suggest to check TPS62293-Q1.
