    Track Width for 6 A, 2oz

    The thin tracks carry 10 A? or only the big ones?

    Track Width for 6 A, 2oz

    Though that you mean heat will spread to heat the FR4 layer and the components, OK got you. I'll make copper area as you guys suggest, and make the tracks as big as i can. Thank you both ZASto and KlausST :smile:

    Track Width for 6 A, 2oz

    Hello, I mean my computer power supply called: switching power supply and it's rated for 35 A, i remember i break one it's on pcb i ask because heavy weight pcb expensive. My circuit will work on 6A DC, but there is capacitor supply ripple current with 60 kHz switching. ZASto i don't know...

    Track Width for 6 A, 2oz

    Sorry i wrote wrong, i mean if i reduced the temperature rise (not time rise) the tracks became thicker. Another thing need to know, how the power supply pcb withstand 35 A and more? at same time it's not expensive because total cost of power supply not high. My understanding is that i'll make...

    Track Width for 6 A, 2oz

    OK, then i must lower the rise time but it will give more thicker tracks.

    Track Width for 6 A, 2oz

    Hi Klaus, Normal PCB from fiber glass FR-4, other heat sources will the the component themselves but not much, the working temperature maybe 70°C (Including ambient), will case it later and add fans for ventilation.

    Track Width for 6 A, 2oz

    Thank you ZASto, so as i told i have only one copper layer at the bottom and over it just the solder mask layer, so it's OK i use the 70 mil?

    Track Width for 6 A, 2oz

    Hello, I will have a max current of 6 A flows in the PCB, i chosed copper thickness: 2 oz And i calculated it from: https://www.desmith.net/NMdS/Electronics/TraceWidth.html It give nearly 70 mil track width for external but 186.74 mil for internal, my pcb will have solder mask layer over the...

    Thank you both, i understod it now.

    MOSFET Driver TLP350

    Hello, I'm confused in mosfest drivers, i'm using TLP350 and the load i switching using MOSFET is about 7 A, but driver max output current is 2.5 A, Is there is any relation between load current and the driver current? I'm limited by the driver or not? Thanks.
