Part Number: TPS92513

Hi all.

My customer uses TPS92513.

When enable is high, the LED starts emiting light after 500 ms.This is normal pattern.
However, when enable is high, the LED starts emiting light after 5~8 sec.

I would like to know the defferential. What could be the cause?
Have you experienced such a problem?

If you need the schematics and waveform, I can send the file,
but the data is confidential.
So please give me the message to the following e-mail.
e-mail : ogane-s@clv.macnica.co.jp

I would like to get your comment as soon as possile.

Best Regards,
Sho

    Hello Sho,

    That isn't something I have seen so waveforms and a schematic would be helpful. I would also like clarification of the issue because the first two sentences describing the issue aren't exactly clear to me. I will send you a direct e-mail.

    Regards,

    Clint
