Part Number:MSP-EXP430FR6989
Tool/software: Code Composer Studio
I have a unique situation where the EnergyTrace switching regulator is actually causing noise on sensitive sensor lines of my project. I need to disable the switching power supply on the EnergyTrace section of the development board. Is there a way to do this?
If I'm understanding the schematic correctly, I believe the development board has the ability to switch between the EnergyTrace switcher (T101) power and the linear regulator (IC101) via a solid-state switch (IC103). Is this true? If so, how do I switch between the two power sources? Will switching to the linear regulator keep the switching regulator from switching?
I'm using the MSP-EXP430FR6989, but I'm guessing my questions are somewhat universal for all of the EnergyTrace enabled debuggers.
