The datasheets for the TLC5947 and TLC5955 (both TI parts related to my selected TLC5951DAP) state that

several electrolytic capacitors must be placed on the board equally distributed to get a well regulated LED supply voltage (). The voltage ripple must be less than of its nominal value.

I will hence need to select the correct value of electrolytic Capacitors to bypass this LED supply voltage.

As with my Current Amplifier design, I will use LTspice to help me validate my design.

I know that

each row is conducting with Minimum Data Frequency
it charges back up when the row is not conducting? In reality, it is a DC supply? If PD, should not drop??
