DPA-Switch系列器件具有TOP和Tiny系列的技术特点,采用脉宽调制(PWM)和跳周期调制(PSM)相结合的新型调制方式来调节输出电压,并具有低功耗和高效率等优点。利用该系列器件设计一种小功率四路输出的单端正激式开关电源,给出了简化设计步骤和参数计算。
- Abstract:
- DPA-Switch series the advantages of TOP switch and Tiny switch, integrated with PWM and PSM to regulate the output voltage,and with the advantages of low cost and high efficiency. A lower power four output switching mode power supply (SMPS) circuit is designed based on DPA-Switch series. Simple design steps and parameter preference are given.Reliable working performance and stable output is showed from the experiment.
