The measured Switching frequency is less than expected. Resistor we use for Rt is 6.2kOhm 1%. Normally we should have around 2Mhz switching for this resistance value but what we measure is 1.7Mhz. Is it a problem, what can be the reason. Please help

Hi Hariha,
There are many reasons that can make switching frequency drop, such as reaching Ton-min or Toff-min time, overcurrent protection and short circuit detected, so you should pay attention to test condition.
