    Safe distance from Power MOSFET

    Hello friends

    Safe distance from the LCD to power MOSFET should be how much?
    And what is the standard for calculating this

    IRFP250
    Vds = 24 V
    Id = Max 4 A
    Vgs=15v
    Ferq = 10 KHZ
    Driver = IR2104

    Re: Safe distance from Power MOSFET

    Hi

    The problem is not the "distance".
    Itīs the current flow and the impedance...that may cause error voltage.

    Easiest way:
    --> use a proper GND plane (one layer just for GND, no other signals) and use decoupling capacitors.

    thank you but i want what is the standard for calculating this distance for reduce the error voltage effect
