LM25184: schematic review

Part Number: LM25184


Hi,

Would you please help to review below LM25184 schematic?

Vin=12V , Vout=12V 1A

Thanks!

Jeff

  • Hello Jeff,

    Thank you for using our products.  My review comments for you to consider:

    • R6 and R7 should change to 1206 size at least.
    • Reserve an Electrolytic capacitor position at the input in parallel with C7, in case you need it to help damp the high Q of the input L-C resonant tank.
    • Double check your ceramic capacitors' datasheet to make sure the capacitance does not drop too much under input or output voltage bias. If  needed you may need to choose a higher voltage rated capacitors.
    • D1 does not need a 3A diode, although it should work there.  
    • Please also run our design calculator to make sure your transformer fits.
    • Please follow the layout guideline and refer to our EVM layout when designing your PCB.

    Good luck in your project.

    Regards,

    Youhao
