Some applications require a positive voltage to be generated from a negative input voltage. This can be done either by using a transformer based topology, such as a flyback converter, or with a ...

Some systems, such as optical networks, require more than one negative voltage. A common procedure is to boost the main negative supply of –5V to –10V and then reduce it with a linear regulator to –9V ...

Electronic equipment uses predominantly positive voltage rails for power; occasionally, some negative voltage rails are also used. For this reason, negative (or inverting) output DC-DC converter ...
