Tracking soft start circuit

摘要

A tracking soft start circuit architecture contains a plurality of soft start circuits for generating a plurality of soft start voltages during startup for application to associated power supply terminals of a power supply system. The soft start circuits are interconnected in such a manner that prevents any soft start circuit from generating a soft start voltage waveform until all of the controlled power output devices have been brought to the same prescribed state of operation, that is, all power FET gates are precharged and their source voltages match each other.
