Re: S2_LP SMPS inductor
2023-07-03
Hi, no 2.2µH coil can NOT be used for S2LP transceiver SMPS block. It is not the same design than WB MCUs.You MUST follow the characteristics described in S2LP datasheet: regardsCyril
Re: Where could I find the BOM of components in Fig. 4 of the S2-LP datasheet? There are different passive components like L7, C21 and C16 using the S2-LP in combination to BALF-SPI2-02D3 for 433MHz. And knowing the values would reduce the time of design.

Hi, we suggest you to use L7: 100nH (LQG reference as example), C21 & C216=100pF used only to DC cut.
