Abstract :
The paper presents different methods of using MC34063 and muA78S40 monolithic switching regulator subsystems to construct dual switching power supplies with step-down and step-up converters. General description of MC34063 and muA78S40 operation modes, mathematical design applied on numerical examples, PSpice under ORCAD simulation of the whole switching power supply and practical implementations are included. Some practical considerations are also specified.
