Hello Lawrence,

Everything on the schematic looks ok, I see no issues. Only recommendation is if possible add an electrolytic capacitor at the output. This seems like a low conversion ratio application so at low brightness %s the boost might enter into DCM/PFM mode switching. It is always preferable to add an electrolytic capacitor in order to avoid any audible noise issue as boost switching frequencies during DCM/PFM can get close to audible frequency range.
