Efficieny from LTSpice Simulation is much less than Eval Board MAX17555C EV Kit

Category: Hardware
Product Number: MAX17555

Hello, 

I am evaluating MAX17555C for my 12Vout & 30mA_Iout_max application where the Vin is 24V. The simulated circuit on LTspice is same as that of Eval kit but LTSPICE shows 70% eff at 30mA while Efficiency vs Load Current curve from MAX17555C Evaluation Kit shows 88%.

Please can you confirm if the LTspice model of MAX17555C is accurate enough to estimate the efficiency values ?
