Abstract
h055721120 A power supply unit comprising an output controller which is supplied with an input voltage from a voltage source and controls the output voltage, an output voltage detector for detecting the output voltage, a stable operation signal generator that generates a signal for stably operating the output controller, and a reference signal generator for generating a reference signal, wherein the output voltage is produced by controlling the output controller based upon the signals from the output voltage detector, stable operation signal generator and reference signal generator, and wherein provision is made of an input voltage detector for detecting the input voltage and a stable operation signal-level changer for changing the level of the signal in response to fluctuations in the input voltage to improve the operation of the stable operation signal generator.
