This is a follow-up question on my previous thread:http://support.dialog-semiconductor.com/disable-buck-converter
To skip the buck, one option from the above thread is as follows:
-SWITCH is connected to VDCDC by means of a 1K to 10K resistor, Vbat1V is grounded: 0V
-VBAT3V = VBAT3V_RF = VDCDC = VDCDC_RF = 3.3V max
However, we found the following spec in the data sheet Table 281:
VPIN(VDCDC_ RF) -- voltage on the VDCDC_RF pin -- Supply voltage on VDCDC_RF needs to be between 0 and 2V.
And if we connect VDCDC_RF to 3.3V, it will be out of this range. Will this still be OK? Thanks.

Hi enormous,
Yes, the Vdcdc, Vdcdc_RF supplies can be connected to the same supply as Vbat as well, up to 3.3V. The limitation is just to be on the safe side.
Thanks MT_dialog
