PT4105实测数据

输入                            输出                     效率

5V  150mA                   3.2V 200mA            0.853
10v 84mA                    3.2V 200mA            0.761

5V  340mA                   3.5V 400mA            0.823
10V 170mA                   3.5V 400mA            0.820

5V  700mA                   3.9V 700mA            0.780
10V 400mA                   4V   800mA            0.80      

以上实测数据,电感是47uH .温度高达50度.觉得效率有点低,是否还能提高.
