During sleep time of the product, there are continuous peak currents (ripple currents) observed at input of TPS62737- Vin pin. During wake-up period ripple in the current are reduced to 1mA. Why there are high peaks during low current consumption.

Below are the input current waveforms captured with only TPS62737 connected to a resistive load of 4.5kohm. R37 is remove and load mentioned in waveform are connected across C32
Here 4.5k ohm load represent sleep current of our product and we are observing 10mA peak currents due to which battery life is reducing. Let me know why these peaks are appearing at the input of Vin pin.
