Please let me know about Constant Current decides time of TLC5916.

(after perform of CurrentAdjust by SpecialMode)

※I didn't find written on the datasheet.

Is it depend on change of a current value?

Best regards,

    Hi Satoshi,

     

    As discussed in the "Writing Configuration Code in Special Mode" section on page 21 of the datasheet:

    "the timing for writing the Configuration Code is the same as the timing in the Normal Mode to latching output channel data"

    Since the LEDs must be disabled in order to write the configuration code (OE = high), the new current value will not take effect until the after the LEDs are enabled (OE = low).   Figure 8 shows the timing for OUTn turning on after it has been enabled via OE.

    Let me know if you have any other questions.

     

    Best Regards,
