1. DCDC Low Noise DCM Mode = Light Drive (PFETCNT=NFETCNT=3), F=3.0 MHz (RCOBAND=0), ANASW=DVDD
2. CMU_HFXOCTRL_LOWPOWER=0
3. DCDC Low Noise CCM Mode = Light Drive (PFETCNT=NFETCNT=3), F=6.4 MHz (RCOBAND=4), ANASW=DVDD
4. DCDC Low Power Mode = Medium Drive (PFETCNT=NFETCNT=7), LPOSCDIV=1, LPBIAS=3, LPCILIMSEL=1, ANASW=DVDD
4.1.5.3 Current Consumption Using Radio
Unless otherwise indicated, typical conditions are: VREGVDD = AVDD = IOVDD = 3.3 V, DVDD = RFVDD = PAVDD. T_OP = 25 °C.
Minimum and maximum values in this table represent the worst conditions across supply voltage and process variation at T_OP = 25 °C.
See Figure 5.2 EFR32MG1 Typical Application Circuit: Configuration with DC-DC converter (PAVDD from VDCDC) on page 64 or
Figure 5.1 EFR32MG1 Typical Application Circuit: Direct Supply Configuration without DC-DC converter on page 64.
