HI,

BREG has no output, what could be the reason? The schematic check shows no problem.

Hello User,

There is a chance the preregulator is not enabled. REG0 drives the base of the external NPN BJT using the BREG pin. To enable the preregulator, follow the instructions in Section 6.3.1 Preregulator Control of the technical reference manual.

Best Regards,
Alexis
