A new multiphase interleaving buck converter with bypass cell capacitor and inductor

As the number of transistors in microprocessors increases per Moore´s Law, their power requirement increases accordingly. This poses design challenges for their power supply module especially when they operate at sub voltage range. This paper presents a new multiphase topology that addresses these challenges. Laboratory tests on a hardware prototype of the topology shows improved load regulation, output voltage ripple and dynamic response time compared to a commercially available power supply module.
