Electromagnetic interference can emanate from high di/dt loops found in some switch-mode supply topologies. New controllers overcome these difficulties by integrating key components inside the chip package. Tony Armstrong | Power by Linear, Analog Devices Inc. It goes without saying that PCB layout sets functional, electromagnetic interference (EMI) and thermal behavior of every power supply […]
