Hi, colleagues,
according to documentation the LTC4120 and 25 are searching for a resonance at 2.5 kHz, which is an audible frequency. Does it hurt the experience of the user of this technology? Is it heard when the system is in energy transfer mode?
From the LTC4125 datasheet, p 10.
The transmitter starts with at 2.5kHz but quickly synchronizes to the resonant frequency of the transmitter LC circuit. This frequency is typically hundreds of kilohertz…

Thank you, now it's clear!
