LT3517 low output current, why?

I'm testing boost convertor with LT3517 and I have lower output current than expected. Input voltage is 12V or higher, output voltage depend on condition, but max 37V and out current should be 200mA. I have 0R47 resistor between pin ISP and ISN, so without correction on pin CTRL should be approx. 210mA. Problem is, I have only 180mA on real circuit, so why? Wrong inductor or something else?

Thaks for help.
