LTM4644 frequency-synchronization-and-clock-in-requirements-for-parallel-channels

Hi , 

This is a continuation of FAQ .

I Understand that we need to tie RUN, TRACK/SS, FB and COMP pin to use the paralleling operation.

But as each control module has its own oscillator, after power-up will all the module be running with the CLKOUT from the first module.

The first module will run with an internal clock and provide the clock for CLKIN of the second module and so on.

One more quick question of how to select from the internal clock or clock from the previous module.

Thanking you 

With best regards and wishes
