典型应用 |
使用注意事项：
输入电源的要求
产品的输入端必需接一个低阻抗的电压源，如果电压源阻抗过高或者电压源与产品的输入端之间的连接线过长会造成产品不稳定。在产品的输入端（尽可能靠近产品的输入引脚）接入一个低ESR的电容，可有效解决此问题的发生。例如，24V输入的产品，可接22μF的电容。 ② 降低输出纹波
若要求进一步降低输出纹波，可在输出端并联一个合适的滤波电容或接入一个“LC”滤波网络。需要注意的是输出端的外接电容不能选太大，否则可能会造成启动问题，具体请参考产品的***输出容性负载要求。“LC”滤波网络的带宽应远离产品的工作频率范围。一般情况下，在输出端接入一低ESR的滤波电容即可满足要求，通常Co=100uF。 ③ 输入电流
当输入电源电压不稳定时，请确保其输出电压波动范围满足产品的输入要求；输入电源的输出电流必须足够应付该产品的瞬时启动电流Ip，一般: Ip =2-4*Iin-max。 ④ 此产品不能并联使用，不支持热插拔 |
