  • RE: LM5030: LM5030 push pull step up

    Resolved
    Hello Watchaphong, You could use the LM5030 for such an application however 100kHz is below the minimum operating oscillator frequency of the ic. You should consider using the UCC2808A-1 or the UCC2808A-2 which is another push pull controller and…

  • RE: UCC2808-2: Repeated fault analysis

    Hi Alon, It meant ambient temp rather than junction temp. 87C Ambient temp exceed max recommended operating range of UCC2808-2. Can you lower the ambient temp to see where the part starts switching? For the UCC2808A-2Q1, I compared it against UCC2808A…
