Abstract

The paper presents a DC-DC step-up/down converter used in switching power supply with monolithic switching regulator control circuits. The paper completely describes the design of the switching power supply starting with the simplified mathematical theory of the DC-DC step-up/down converter, getting on with the general description of MC34063 and muA78S40 operation modes and then with the mathematical theory of the DC-DC step-up/down converter in boundary conduction mode controlled by the switching regulation control circuits, the PSpice simulation of the whole switching power supply, a numerical example and ending with itpsilas practical implementation. Conclusions about the efficiency of the switching power supply are drawn and some practical considerations are also included.
