MOSFET GATE DRIVE WITH REDUCED POWER LOSS MOSFET
A gate driver for a power MOSFET in, for example, a DC-DC converter switches the MOSFET between a fully-on condition and a low-current condition instead of switching the MOSFET between fully-on and fully-off conditions. The amount of charge that must be transferred to charge and discharge the gate o...

Summary: | A gate driver for a power MOSFET in, for example, a DC-DC converter switches the MOSFET between a fully-on condition and a low-current condition instead of switching the MOSFET between fully-on and fully-off conditions. The amount of charge that must be transferred to charge and discharge the gate of the MOSFET is thereby reduced, and the efficiency of the MOSFET is improved. A trimming process is used to adjust the magnitude of the voltage supplied by the gate driver to the gate of the power MOSFET in the low-current condition. |
