Hi, VincenzoThanks for your reply.I think the "Vdropout"(= ILOAD *( RDSON, PFET + RINDUCTOR)) will be up to approximately 0.5V ,So if the Vin is 5V, we can set the Vout to above 3.3V ,right?or is...

View ArticleForum Post: RE: TPS65217D - Which is the "always-on supply"?
The always-on supply is a diode drop below VSYS. The current is negligible. Typically the node is high. When it is pulled low, there is a small current that flows through the pull-up resistor.
