No magnetics required - charge pumps can handle the Volts!
Design How-To  
8/28/2012   Post a comment
The charge pump in some ways has been nearly forgotten due to limited voltage range and historical performance that placed it somewhere in between an LDO and a switching regulator. In this Product How-To article, Steve Knoth at Linear Technology suggests designers -who do not like to use inductors- to use high voltage charge pumps instead.
