Reproduce circuit Power PWM Module

Hello everyone!!

I was trying to reproduce the circuit of the board in the figure. It's a Pwm module which can provide 10A of 3-30V for applications such as dc motors, brushless, etc...

I also recognize the mosfet P3010L and also the Si8711CC (opticoupler), but didn't figure out the exactly circuit.

Can anyone help me to design this? Maybe a provide a ilustration of it

Board:

I can't see a board or a figure. 10 Amps at 30 Volts is a lot of power. Don't make any mistakes !

Please provide a link to the datasheet or product page of any hardware you mention.
