Embedded SMPS
7.8 Embedded SMPS
NUCLEO-WB55RG embeds an SMPS to optimize the power consumption. All the details of this part are
explained in the datasheet and the reference manual of the NUCLEO-WB55RG. NUCLEO-WB55RG allows the
evaluation of the SoC with this SMPS active. All the components necessary for the operation are present.
Moreover, it is possible to bypass the SMPS. For that, it is first necessary to stop the SMPS by firmware (Refer to
the SMPS section in the datasheet and user manual). And in a second time, it is possible to bypass the SMPS, for
that it is necessary to close SB23.
