LM5155: The design outputs a 150V voltage with the lm5155 boost circuit, but the output voltage is only 100V when the load is 500R

Part Number: LM5155

Tool/software:

I am building a boost circuit using LM5155, with an input of 24V and an output of 150V/500mA. When unloaded, the output is normal at 150V, but as the load increases to 3kohms, the output voltage begins to drop. When the load is 300R, the output voltage drops to 100V. How can I improve the circuit to meet the design requirements? Can you give me some advice? Thank you
