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.
