IWR1642BOOST: how can i reduce the Acoustic Noise in the IWR1642BOOST

Hello,

The DC to DC converter LP87524B generates the 4 Buck converter power supplies.  There is TI training to discuss improving electrical performance.

"training.ti.com/achieving-low-noise-and-low-emi-performance-dcdc-switching-regulators"

There is also a discussion of reducing the acoustic noise of the power subsystem, in the E2E for Power components.

"e2e.ti.com/.../how-to-reduce-acoustic-noise-of-mlccs-in-power-applications

If the PMIC itself is making acoustic noise, a thermally conductive, electrically insulating, sound muffling top pad can be installed.
