Part Number:CC2640R2F
Tool/software: WEBENCH® Design Tools
my embedded system contains:
CC2640R2F - 1.8V and 0.03A
module A - 1.8V and 0.2A
Module B - 1.8V and 0.002A
module C - 1) 3.3V and 0.4A
2) 3.3V and 0.1A
TI power WEBENCH Power Architect proposed to use LM3670-1.8V and TPS63051. However, LM3670-1.8V is not a multi-output regulator so all the 1.8V output load needs to share the voltage. Due to this, i cannot turn off each module completely to save power.
on the other hand, im looking at PMIC and found a really cheap PMIC, LP3923. This PMIC have only single switching regulator and the rest are linear regulators (LDOs). Due to this the power consumption will be high!
This is for wearables so the design have to be small, low power/high efficient and also low cost.
Please help me with my power management issue.
