Part Number: TPS61252

Could you let me know the TPS61252 switching frequency range?
There is only typ value on datasheet. Reference value is OK.

Best Regards,

    this device is not fixed frequency, it bases on adaptive on time control to set the frequency at approximately 3.5MHz. the frequency varies with the input voltage, output voltage and current. based on the measurement in the EVM, at VIN=3~4.2V, VOUT=5V, IOUT=100~900mA, the frequency range is 3.3MHz~4MHz. (make sure the deice operates at PWM mode, not power save mode) the frequency increases with the load.
