As is widely known, temperature also dramatically affects the flux and color output of the LEDs themselves, which can make the visual appearance of a row of fixtures appear to not be in sync.

A SYNC output and phase detector are included to simplify designs requiring tracking to an external signal source.

To set up a sync point coincide with a natural commutation point in OTC products, and will be able to improve reliability and stability of the phase shifting trigger and output of the power source.
