Now with 9V to 15V input range, direct gate drive and 500mA LED
current.

But I'd rather use a TPS562208, which would be cheaper and simpler and
has spread-spectrum to help the EMC thing by about 20 dB.
Thanks for circuit and the chip reference John. That meets my cost
requirement.
I always felt that spread spectrum for EMC was cheating but I'm aware that
there are good arguments why it is not.
Also many thanks to piglet for taking time to post circuits.
