LM5122-Q1: four-phase time use synchronous clock

hi Brigitte

and  how to connect 3 phase in SCH？thanks in advance

dear

 thanks brigitte reply

      we need to design and 120-degree phase-shifting external signal synchronization, using LTC555 clock output drive frequency to decimal counter show in TIDM960.PDF

          CD74HC4017, phase-shifting, the current CD74HC4017 output 001 010 011 100 101 and so on achieve different LM5122 to produce out-of-sync (time difference) work, thus achieving phase difference, and then different phase signal superposition to form the maximum output power? I do not know about the principle，thanks

Hi Raymond,

This is a divide-by 6 circuit using one CD74HC4017.

yes，4017 output control per LM5122,and different LM5122 will take turns work in the same time，they will output max power，but how  to promise their phase  difference is 120 °，but not 90° nor other degree？

Hi Raymond,

For this divide-by 10 circuit, the phase is 36°.

For divide-by 6 circuit, the phase is 60°.

Best Regards,
