120w多路输出变压器计算参数校正

输入100-240V           输出5路:19V/4.5A ;                   开关频率  60KHZ                 效率 0.80          磁芯POT3319 ;
                                                       5V1A
                                                       5V2A 
                                                       5V1A
                                                       5V2A 

             计算结果:                   Lp=300UH
                                                 Np=48T       线径0.5mm;                  
                            19v绕组        Ns=12T       线径0.6mm*2;
                            5V1A绕组       Ns1=4T      线径0.4mm;
                                                  Ns2=4T
                            5V2A绕组      Ns3=4T       线径0.6mm;

                                                  Ns4=4T

                                Vcc 绕组     Nvcc=9T    线径0.2mm;
