To sequence multiple converters to start at the same time (set output voltage is reached at the same time), the following schematic may be used:
To sequence multiple power module start-up times the power good (PGood) pin and the CTRL pin may be used. In below schematic,
the RPM(n) starts after RPM(1) reaches its set output voltage and the power good signal is set to high which then enables RPM(n).
After RPM(n) reaches its set output voltage, it enables RPM(n+1).
