Dear Sir's,
I have attached the schematics of the master and of the slave module of the LM5143 in single output 4 phase mode.
The master in single operation works, master and slave combinaton show that only the master works.
Could yhou check the wiring of the slave? I meassure 5V on VCC1 and VDDA2 on the slave module. VIN is 36V.
I measure a PWM signal on pin 33 (DEMB) of the slave. The FETs are not switched on the slave module.
Attaches are the 2 schematics, the shot of the sync signal on pin 33 of the slave device and a overview picture.
Best regards,
Jochen
