LM3880-Q1: t_enable_delay resut

Part Number: LM3880-Q1

Tool/software:

Hi,

On datasheet page of 10 there is a Equation 1 that is used for t_enable_delay.

What is the result of calculation - is it ns or ms?

Also can you give an example of calculation with "common" Cen calue.

Sincerely,

Juha

    Hi,

    When this t_enable_delay start "counting"?

    Does it start counting when chip is enabled via EN -pin?

    "When the LM3880-Q1 is enabled, the three output flags sequentially release, after individual time delays"
    "Upon power up, all the flags are held low until this recision enable is pulled high. When the EN pin is asserted, the power-up sequence starts."

    Regards,

    --juha

    Hi

    It is second assuming that you use V/A/F as unit.

    No, the cap is to delay to rise the EN pin and it starts after the VCC reaches 1.25V.

    Regards
