Hi,
The audible noise occurs from inductor or capacitor when disabling the power save mode and using TPS61201 under the load condition of less than 5mA.
Then, the output voltage ripple of 40mVpp can be observed at a frequency of several 10kHz when monitoring with an oscilloscope.
So, could you please tell me how to improve the audible noise and decrease output voltage ripple?
I would share the customer schematic via a private message with you if you can accept my friendship request.
Best regards,
Kato
