| Abstract: | This paper designs a multi-output single-ended flyback switching power supply using UC2844 current mode PWM controller. According to the design method using UC2844 current control mode to give single-ended flyback topology and based on the peak current PWM technology, by testing the signal waveform it is demonstrated that the design of this method can reduce the switching power supply ripple, improve the power supply efficiency, and ensure stable voltage output |
