7.6 Power Consumption Summary

Table 7-3 and Table 7-4 summarize the power consumption at the power terminals.

Table 7-3 Maximum Current Ratings at Power Terminals
PARAMETER(1) SUPPLY NAME DESCRIPTION MIN TYP MAX UNIT
Current consumption VDDIN, VIN_SRAM, VNWA Total current drawn by all nodes driven by 1.2V rail 850 mA
VIN_13RF1, VIN_13RF2 Total current drawn by all nodes driven by 1.3V (or 1V in LDO Bypass mode) rail when 3 transmitters are used (2) 2500
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(3) 50
(1) The specified current values are at typical supply voltage level.
(2) Three transmitters can simultaneously be deployed in the AWR2243 device with 1V / LDO bypass and PA LDO disable mode. In this mode 1V supply needs to be fed on the VOUT PA pin. For a 2Tx use case, the peak 1V supply current goes up to 2000 mA.
(3) The exact VIOIN current depends on the peripherals used and their frequency of operation.
