LMZM33603: About EN/SYNC pin

Part Number: LMZM33603

Hi,

Customers use the SYNC pin for frequency synchronization.
However, customers want to use the EN pin for sequence control.
Since multiple PWM synchronizations are performed, PWM can not be made Low.
Could you tell me an example of a circuit to EN = LOW when using the Sync function.

Best Regards,
Yusuke

  • Hi Yusuke,

    Use an open drain device to interface with the EN pin and apply a LOW voltage to disable the device. See below.

    Thanks, Jason
