The monolithic half bridge reduces overall system size by eliminating the PCB space needed for interconnections between transistors. In the example shown here the board space needed for two discrete devices is 110mm². By going to a monolithic half bridge, the board space required is only 80mm², a savings of 30%. Saving space is only a small part of the story however. By eliminating the power loop inductance that is caused by the interconnection of two discrete devices, the engineer can speed things up.
