6.6 Power Consumption Summary

Table 6-3 and summarize the power consumption at the power terminals.

Table 6-3 Maximum Current Ratings at Power Terminals
PARAMETER SUPPLY NAME DESCRIPTION MIN TYP MAX UNIT
Current consumption VDDIN, VIN_SRAM, VNWA Total current drawn by all nodes driven by 1.2V rail 1000 mA
VIN_13RF1, VIN_13RF2 Total current drawn by all nodes driven by 1.3V or 1.0V rail (2TX, 4 RX simultaneously)(1) 2000
VIOIN_18, VIN_18CLK, VIOIN_18DIFF, VIN_18BB, VIN_18VCO Total current drawn by all nodes driven by 1.8V rail 850
VIOIN Total current drawn by all nodes driven by 3.3V rail 50
(1) 3 Transmitters can simultaneously be deployed only in AWR1843AOP and AWR2243 devices with 1V / LDO bypass and PA LDO disable mode. In this mode 1V supply needs to be fed on the VOUT PA pin. In this case the peak 1V supply current goes up to 2500 mA.
