TLV62090: Internal capacitance between FB and VOS

user5612199
Prodigy 20 points
Part Number: TLV62090

Hello,

I will use this product for DC voltage converter.

Is there internal capacitance between FB and VOS?

If so, would you tell me that capacity?

Best regards,


Kenichi

    Hi Kenichi,

    I am not sure if there is any physical capacitor connected between the two pins. Any valuable information that is not confidential can be found in the datasheet. Based on the block diagram below, I do not see any capacitor connected between the pins.

    Can you share the reason why you ask? I might be able to help further.

    Thanks,

    Zain Riaz

    Hi Zain Riaz,

    Thank you for your reply.

    An abnormal output problem has occurred due to the mismatch between the internal capacitance and the external resistance with other company's power IC.

    Other company's IC has internal capacitance by design.

    So we wanted to know that.
    Regards,
    Kenichi

    Hi Kenichi,

    Thanks for sharing the information. If you like I can look at the schematic diagram and any waveforms that show the output problem.

    Looking forward to your reply.

    Best Regards,
    Zain
