When the PWM input goes high, the high−side driver will begin to turn on the high−side MOSFET using the Bootstrap Circuit stored charge of the bootstrap capacitor. As the high−side The bootstrap circuit uses a charge storage capacitor MOSFET turns on, the SW pin will rise. When ...
Driver circuit generates rapid-voltage-transition pulses needed to switch high-power metal oxide/semiconductor field-effect transistor (MOSFET) modules rapidly between full "on" and full "off". Rapid switching reduces time of overlap between appreciable current through and appreciable voltage across such...
