Abstract :
Based on the characteristics of switching power supply, this paper, taking MC34063A IC as the research object, has proposed the design, realized design of single-transistor positive buck DC-DC converter through calculation and component selection, and simulated the circuit of the design using Saber software. When the input voltage is 15V~25V, the output voltage has been stabilized within the scope of the 12.181V, with its ripple coefficient being 0.1154%, so it has satisfied the requirements of the design.
