TLV62569A: Max Cout and ESD diode from EN to Vin

Russell Wetherley1
Expert 4255 points
Part Number: TLV62569A

I have two questions.  

What is the maximum allowed Cout on the TLV62569A output?  Customer has 91uF of Cout (before de-rating) with 1uH in 1.8V application.  

Also, is there an ESD clamp on EN pin?  What does the structure look like?  Is there a diode tied to Vin?

    Hi Russell,

    The maximum optimal value for Cout is 47uF. In case the customer wanted to use a higher Cout value, then they need to verify the loop stability, ripple voltage, and transient response if it meets their specification.

    I need to verify if there is an ESD clamp on the EN pin. There will be a significant delay in the response because most people are on vacation leave already.

    Best regards,

    Hi Russell,

    The designer is still on vacation leave and will be back in the office on Monday.
    As we are already discussing your queries internally, so I will close this thread.

    Thank you.
