Hi Leon,

See feedback below:

I'd recommend changing output capacitance to 3 x 47uF, have a Rff of 4.99kOhm and Cff of 33pF for design robustness with improved transient performance following Table 9-3.
The schematic currently has switching frequency of 400kHz and can go to 1.5MHz using Rt resistor. I'd suggest changing the input high frequency capacitors from 0.1uF to 0.47uF. This should help with high frequency attenuation.
Everything else looks okay.

Regards,

Jimmy
