Abstract

PURPOSE:To smoothly make an output voltage respond to a step like change of a reference voltage, by constituting a voltage controlling system and a current controlling system controlling the output current by a current reference signal generated from the voltage controlling system. CONSTITUTION:A reference voltage Es is applied to a + input of an of an error amplifier AMP2, an output voltage feedback signal 3 is applied to a - input via a resistor R1 and a voltage controlling system for stabilizing an output voltage E0 by controlling a transistor TRQ2 in accordance with the output of the AMP2 is constituted. An overvoltage 8 proportional to a load current 11 across a load current detecting resistor Rs1 is defined as a current reference signal and applied to a + input of an error AMP1. A current feedback signal as a result of a voltage drop of a detection resistor Rs2 proportional to the current 11 is applied to a - input of the AMP 11 to constitute a current controlling system 12. The output of the AMP 1 is applied to a + input of a comparator COM, an output from a triangle wave generator TG is applied to a - input of the COM, a TRQ1 is controlled by the comparison output of the COM to stabilize an output current 9, allowing to smoothly respond the voltage E0 to the fluctuation of the voltage Es.
