The evolution in integrated circuits for data processing such as microprocessors poses new challenges for their power supplies.The requirements are lower output voltages with higher currents,fast transient capabilities,high power density.high efficiency and high reliability.The Magnetics Integration (MI) techniques can help the Discrete Magnetics(DM) in the switchmode power converters to reduce the core loss,core size,or ripple current.As a result, the power density and the capability of the power converter...
