Abstract :
Many of today´s microprocessors require voltages in the 3.3 volts DC range. 5 volts DC to 3.3 volts DC conversion (usually the most efficient) requires a duty cycle of over 50%. Because of this, increased performance can be realized by using a dual-phase DC/DC power converter topology. 90%+ efficiency can be achieved with less stress on the input (host system) and output filter components
