Hi there,


We have PTN5110 and would like to know how to source high voltage (more than 5V). 


From the datasheet. it seems that if you want to support higher voltage, you need to use the EN_SNK1 pin to enable this. This means we need two separate power source, one or 5V and the other for anything above 5V. Is this the only way (ie 2-rail power system) or can we have 1 rail power source and use EN_SRC to supply 5V to 20V output?
