DC-DC REGULATOR WITH SWITCHING FREQUENCY RESPONSIVE TO LOAD

摘要

A switch mode power supply in which the switching frequency is controlled by an oscillator having a nominal frequency, and having an error amplifier to provide an output signal which represents departure of the power supply output from a nominal value, and which functions by adjusting the frequency of the oscillator to a frequency which is higher or lower than the nominal frequency according to the value of the error amplifier output signal.
