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

Many thanks
 

Hi

The problem is not the "distance".
It´s 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
