Firstly, the closed-loop control principle of IC3525 chip is briefly introduced. Next the mathematical model of Push-Pull circuit with IC3525 control and the controller algorithm are achieved. Finally, the system simulation model is made by using MATLAB software. The simulation results show that the digital Push-Pull circuit controlled by IC3525 is feasible.　 Keyword：Push-Pull, Digital, Model , Simulation
