摘要
设计了一款宽输入电压、高效率、低纹波的直流-直流(DC-DC)稳压电源。该稳压电源输入电压范围为15V^25V,输出电压5V,最大输出电流2A,且瞬态响应速度快、纹波电压小,电路设计简单、体积小。根据开关电源原理,通过计算的方式选择了电感、输入输出电容、开关管参数,为简化设计并提高性能合理选择了控制电路。自制PCB并调试,通过测试来验证理论设计。
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.
