Figure 5.1. EFR32BG1 Typical Application Circuit: Direct Supply Configuration without DC-DC converter
Typical power supply circuits using the internal DC-DC converter are shown below. The MCU operates from the DC-DC converter sup-
ply. For low RF transmit power applications less than 13dBm, the RF PA may be supplied by the DC-DC converter. For OPNs support-
ing high power RF transmission, the RF PA must be directly supplied by VDD for RF transmit power greater than 13 dBm.
