Switching regulator

Abstract

Abstract PURPOSE: To stabilize an output voltage, by comparing the output of an error amplification circuit with that of a charge/discharge circuit and controlling a switching transistor depending on the result of the comparison. CONSTITUTION: The switching transistor Q 1 is turned on and off to intermit a DC voltage to drive a power transformer T. The output of the transformer is rectified and smoothed by a rectifier 12. The output voltage V o is picked out from both the terminals of a load RL. The output voltage V o is compared with a reference voltage by the error amplification circuit 13. A voltage corresponding to the difference between the output voltage and the reference voltage is applied to a control circuit 14. The control circuit compares the outputs of the error amplification circuit 13 and the charge/discharge circuit 15 with each other and supplies a control signal to an oscillation circuit 11 to control the switching transistor Q 1 to stabilize the output voltage.
