CC-wi.Imx53 power

Question

Hi

On the cc-wi.imx53 kit, what is the voltage of VCHRG? there is a chip LM22676TJE-ADJ on the CHARGER part, what is the differents between LM22676TJE-ADJ and LM22676-ADJ?
from the LM22676-ADJ manual, I know that the chip output is 1.3V highest, this will not driver the LTC3125EDCB chip(5V REGULATOR) which input is 1.8V lowest.

Hi, In the HRM Digi will not provide each component information.
It seems the output voltage from this regulator is 5volts.
