Abstract
The invention relates to a microcontroller (MC) having at least one device (G) for generating pulse-width modulated or frequency modulated control signals for a switched-mode power supply. The device (G) has a further device (SQ , SS ) for the alternate charging and discharging an electric charge store (C ) that can be connected to the microcontroller (MC), control means for this device (SQ , SS ) for controlling the charging and discharging operations, and an evalutor for evaluating the time periods which are needed for the individual charging and discharging operations to generate pulse-width modulated or frequency modulated control signals. The microcontroller (MC) generates finely graduated, frequency modulated or pulse-width modulated control signals which are independent of the operating cycle frequency of the microcontroller (MC).
