I'm trying to figure out how to find the right MOSFET to drive a laser using PWM on my 3D printer. I have a Creality Ender 3 Pro that came with the 4.2.2 control board. From what I can tell that board used a TSM060N03ECP MOSFET to provide 24V PWM to the part cooling fan. This MOSFET was also large enough to handle my laser.
I recently upgraded to a BTT SKR 2 control board, which uses much smaller AO3400A MOSFETs to provide 24V PWM to the fans, that can not handle powering the laser. I'd like to leave the board unmodified and use the 24V PWM to feed the gate of another MOSFET, which will in turn provide PWM to the laser. I'm not entirely sure what current the laser is drawing, but I had no issues with the TSM060N03ECP. Ideally, I'd like to find an equivalent to the TSM060N03ECP, but that would accept the 24V gate voltage.
Do I have any hope or will I be better off pulling the 5V Gate PWM signal from the SKR 2 to feed a remote TSM060N03ECP? Thanks for any help you can offer.
