8.6 Power Consumption Summary

Table 8-3 and Table 8-4 summarize the power consumption at the power terminals.

Table 8-3 Maximum Current Ratings at Power Terminals
PARAMETER SUPPLY NAME DESCRIPTION MIN TYP MAX UNIT
Current consumption(1) 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 rail (or 1V rail in LDO Bypass mode), when only 2 transmitters are used.(2) 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(3) 50
(1) The specified current values are at typical supply voltage level.
(2) Simultaneous 3 Transmitter operation is supported only with 1-V LDO bypass and PA LDO disable mode. In this mode, the 1-V supply needs to be fed on the VOUT_PA pin. In this case, the peak 1-V supply current goes up to 2500 mA. To enable the LDO bypass mode, see the Interface Control document in the mmWave Device Firmware Package.
(3) The exact VIOIN current depends on the peripherals used and their frequency of operation.
