Abstract

Perfeccionamientos en circuitos de fuente de alimentación para un procesador de datos, que tiene uno o más accesos de entrada de datos a los que se conecta un circuito de entrada de datos, comprendiendo el circuito fuente de alimentación un primer subcircuito que tiene un estado de funcionamiento en el cual alimenta energía desde una fuente de energía al procesador y un estando de reserva en el cual no alimenta energía al procesador, caracterizados porque el primer subcircuito se conecta al circuito de entrada de datos y, cuando se encuentra en estado de reserva, responde al funcionamiento del circuito de entrada de datos cambiando al estado de funcionamiento, volviendo el primer subcircuito al estado de reserva en respuesta a una salida del procesador indicativa de que el procesador ha completado su funcionamiento.
