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 internal switching frequency of DCDC in nRF54L15 is 8 MHz.

"With such a high switching frequency deviation, the reference design recommends a 4.7uH inductor. Would it be more appropriate to use a 10uH power inductor?"
