Texas Instruments TPS65980EVM
The Texas Instruments TPS65980EVM evaluation module (EVM) helps designers evaluate the operation and performance of the TPS65980: a DC/DC switching regulator that receives power from a Thunderbolt bus ranging from 2.5V to 15.75V on TBT_IN and generates three separate 3.3V supply outputs TBT_OUT, CBL_OUT, and DEV_OUT.
The TBT_OUT supply provides power to the local peripheral Thunderbolt controller and support circuitry. The CBL_OUT supply provides power back to the Thunderbolt cable and has adjustable current limit. The DEV_OUT supply provides power to all other circuitry in the device to perform its designed function.
