Regarding the DCDC of 54L15

[zhanxy]

What is the switching frequency of the internal DCDC in 54L15? What is the function of the FB1 ferrite bead in the reference design? Are there any risks in changing the capacitance values of C1, C2, C12, and C5?

Hello,

The ferrite bead are used to suppress noise coupling to and from the device. It is recommended not to make changes to the reference circuitry as it can degrade the RF performance. Why do you need to change the capacitance values.?
