Hi,
We are using TPS650830 PMIC and learning the EV kit schematic, I don't understand following:
load switch control signals for VCCIO and V1.8U_2.5U are the same load switches output signals;
V3.3A_PCH_LSW control signal is output of V3.3S power good comperator that have to be released much more later than V3.3A_PCH power;
For the system that is not used V1.8U power plane, do I need to connect another power plane to VSB comperator input to get a right power up sequence signalling?
Can you please explain it?
Anna
