To meet the demands of the computer industry's drive to reduce board size and improve efficiency in the microprocessor PWM controller, magnetic manufacturers are searching for new shielded core structures to replace the traditional iron powdered toroidal design. This trend to lower voltages and increased power requirements in microprocessor computing power technology has created challenges in the design of voltage regulators due to increased transient power demands. Tighter voltage regulation is required with improved efficiency and fast transient response time. Most pulse width modulator control chip manufacturers have gone to a power architecture with multi-phase ...
