7.21 Driver
The driver circuit to the gate of the power MOSFET has a current sourcing capability of
typically 170 mA and a current sink capability of typically 700 mA. This permits fast
turning on and off of the power MOSFET for efficient operation.
A low driver source current has been chosen to limit the V/ t at switch-on. This reduces
the Electromagnetic Interference (EMI) and also limits the current spikes across R
