摘要：

A steady output single-ended flyback switching power supply using L6561 current mode PWM controller designed in this paper. The designed circuit consists of single-ended flyback topology and based on the peak current PWM technology. The circuit has input voltage range from 85V AC to 265V AC and about output drive capability of 12V/2A. Based on the specific chip L6561, the novel single-ended flyback AC/DC converting circuit is adapted for mobile or office equipment, off-line battery chargers. The low-power Switched-Mode Power Supply (SMPS) are the most noticeable examples of application that this configuration can fit. The testing results show that the design of this method can reduce the switching power supply ripple, and ensure stable voltage output.
