Yes, sorry, the inductor should have been labelled 220uH, not 220nF.

I'm trying to identify a device that matches the pinout to see if it can help narrow down the specs for the device. So far, the Diodes Inc devices, such as the AP8801SG-13 and the PAM2863ECR are the closest, but the pins don't match up.
This IC came from a laser engraver that is advertised as putting out 3500mW. I'm trying to determine if this claim is even close to reality by analyzing the circuit. I'm also trying to understand how the PWM input works and the function of the 900nF cap on pin 6.
