Note: Pins 1 and 36 and pins 18 and 19 are respectively connected together on the frame inside the IC.
The NC pin can be used as a jumper.
The fin and the package bottom are electrically connected.
To stabilize the chip, the Fin pins should be connected to S-GND and P-GND at a location as close to the TB6585FG as possible.
