    Hi Soumyadeep,

    Thank you for considering the TL7660.  The datasheet gives the oscillator frequency range.  There are two EC-tables, one for VCC=5V and other VCC=3V.  For VCC=5V, the frequency is 10kHz, and for VCC=3V, the frequency is typically 9kHz., with min of 3kHz over the temperature range.  You can also program the frequency by adding a capacitor at the OSC pin, and the program curve is show on page 4th, under different VCC voltages and temperatures. 

    Thanks,
