| Abstract: | With power supply switching converter appearance, the PWM switch technology obtains the widespread application by its simple electric circuit and control principle. The PWM technology Convert power by switching the power class and controlling the duty factor, therefore the ampere and voltage waveform of the main circuit are the pulsation. This paper introduces the constitution and the principle of the integration pulse width modulation system （PWM） controller （UC1525）, and multi-analyses switching power supply＇s control circuit and the driving circuit which constituted by the UC1525 controller. |
