Chapter 6
It should be noted that the maximum total power available for conversion in any regulator
is equal to the input v
oltage multiplied times the maximum average input current (which
is less than the current rating of the switch transistor).
Since the output voltage of the boost is higher than the input voltage, it follows that the
output current must be lower than the input current.
6.2.4 Linear versus Switched
After looking at the specifi cs of linear and switched regulators, it is worthwhile making a
comparison between the linear and switching types. In some cases, switching regulators
can provide major benefi ...
