图1SM74104内部结构图

SM74104 is a high voltage, high speed, dual output driver designed to drive top and bottom MOSFETs connected in synchronous buck or half-bridge configuration. SM74104 also features adaptive delay to prevent shoot-through current through top and bottom MOSFETs during switching transitions. The outputs that drive the top and bottom MOSFETs are controlled by one externally provided PWM signal.
