  • RE: UCC28712: Buck Mode, output voltage fluctuates, intermittant loss of DRV

    Resolved
    Hello, If your design is not starting most likely it is due to a fault. You will have to study CS, AUX and VDD and look at the last three switching cycles before VDD discharges. Since you have a buck design you will need differential probes. If it is…
