Power Down Voltage Regulator (PMU Subblock) Parameters
The PMU Power Down voltage regulator consists of two subblocks:
•
•
Power Down Pre regulator: VDD5VPD
Power Down Core regulator: VDD1V5_PD (Supply used for GPUDATAxy registers)
Both regulators are used as purely internal supplies. The following table contains all relevant parameters:
