![]() ![]() I expect more information is required to give a good answer here, but I already see a number of problems. You say “high power” but the 36V power to the Mosfets are going through multiple. 1 connectors (which are speced at 3A max but I would say even 1 A is likely pushing it). ![]() The mosfet gate is being driven from an optocoupler from a high resistance voltage divider which isn’t low enough (as it will give about 18V on the gate which is speced at 16V max with the swithing threshold at 2.5V so way to much voltage no where near enough current for good drive. ![]() I’d suggest a drawing showing how this fits together, this board with the leds (with their current draw specified) connected where you expect and the driver that drives this board so we can make better suggestions. Therefore, its high current and voltage ratings, low on-state resistance, and fast switching speed make it a preferred choice. Such as motor control circuits, power supplies, and lighting control. On your last board above, the Design Rules Check Off the top you likely want high current screw terminals connected directly to the Mosfet source and drain with large wide traces and a much better drive circuit than is currently present. The IRFZ44N is a frequently used part in electronics where there's a need for high current and voltage switching. Pcb view routing->Design Rules Check is flagging multiple overlaps that you need to resolve one way or another.įirst off, thank you for that design rule check !! really helped out a lot. ![]()
