In the never-ending quest for board space, operating frequency remains the most important variable in a DC/DC converter design. Higher frequency equates with smaller coils and capacitors. A new family of fast monolithic converters that allows circuit designers to reduce the size of their finished products is now available. Other improvements include quiescent currents well below those of slower converters and a new switch-drive technique that ...
