Hi there,
When going through the LP5569 datasheet, I read at 8.5.2.3 that "Using an external clock enables synchronization of LED timing to the external clock signal and is also more power-efficient".
However, I couldn't understand how much more efficient it is to use external CLK, and some data (shown below) leads me to believe that internal CLK is equally or more efficient then external CLK.
I'd like to better understand the advantages of using external CLK in order to decide whether or not to use it in my custom pcbs. Is it more power efficient? If yes, in what case(s)?
Thanks in advance for your support,
Bruno
