8.1.10 Negative Boost Regulator
Another variation on the buck-boost topology is the negative boost configuration. The circuit in Figure 8-2 accepts an input voltage ranging from ?5 V to ?12 V and provides a regulated ?12-V output. Input voltages greater than ?12 V causes the output to rise above ?12 V, but does not damage the regulator.
Because of the boosting function of this type of regulator, the switch current is relatively high, especially at low input voltages. Output load current limitations are a result of the maximum current rating of the switch. Also, boost regulators can not provide current-limiting load protection in the event of a shorted load, so some other means (such as a fuse) can be necessary.
