Swithing regulator utilizing seperate integrated circuits for driving each switch

A high side component for use in a switching circuit for switching an input dc voltage of predetermined polarity, wherein the high side component includes a package comprising:

• a FET having source, drain and gate;
• a driver controlling the gate;
• a voltage input connected to the drain for inputting the high voltage side of the input dc voltage;
• an output connected to the source;
• a logic input for accepting an alternating control signal;
• and
• a logic circuit that controls the driver to switch the FET based solely on the logic input, the logic circuit including a sense circuit that detects the voltage on the source of the FET and controls the switching of the FET for preventing the FET from conducting at the same time as a low side FET connected between the output and the ground side of the input dc voltage.

A low side component for use in a switching circuit for switching an input dc voltage of predetermined polarity, wherein the low side component includes a package comprising:
