Hi Cooper,
The schematic looks pretty good. A few things to point out:
Make sure EN is tied high or connected to on/off control. Do not leave floating.
SS/TRK: this pin can be left floating for 6.3ms timing or place external capacitor.
Make sure the RT pin has a resistor to ground to set the frequency.
Connect the SYNC/MODE pin to ground for PFM and tie to high signal for FPWM.
Regards, Jason
