Other Parts Discussed in Thread: LM5143
Hello Team,
My customer is running into an issue with the LM5143 PSPICE model. The circuit is implemented as suggested in Figure 37 of the datasheet. It works perfectly in single output dual phase mode, but Im not able to get a SYNCOUT signal to be able to use it in 4 phase mode. Also, the SYNCOUT signal is generated by the Slave contoller instead the Master.
The switching’s occur at the same time for both controllers. (Master: SW1, SW2) (Slave: SW12, SW22). The Master Sync output (SYNC_OUT_M)) is not present, instead the sync out comes from slave controller (SYNC_OUT_S)). Also the output voltage is 3,3V instead of 5V.
