Part Number: LM5030
Other Parts Discussed in Thread: UC2827-2, UCC2808A-1, UCC2808A-2

Dear TI Team

I would like to step up 12VDC to 350VDC ~ 380VDC (300W  and  Peak load 600W). and i choose LM5030 for push pull converter.

i have few questions to ask
1. LM5030 suitable for this application?
2. LM5030 can operating PWM frequency below 100KHz?
3. UC2827-2 Current fed push pull suitable for this application?

Regards

    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 can be operated at 100kHz

    Check the part number you specified in question 3.
    This does not appear to be a valid TI part number.

    Regards

    John
