Design Of A high efficiency large current DC-DC Power Supply Circuit
Hu Yusong;China West Normal University;
A Direct-current to Direct-current(DC-DC) regulated power supply circuit is proposed in this paper with improved high efficiency and low ripple, the input voltage range is 15 V~25 V,the output voltage is 5 V and the output current can be up to 2 A. The inductance,capacitance and the switching parameters are selected according to the principle of switching power supply. By making Printed Circuit Board(PCB) and debugging, the test results show that this DC-DC POWER works well with fast transient response high efficiency and low cost.
