Typical Application

Single output

2.Reduce output ripple

If requirement need to further reduce the output ripple, a suitable filter capacitor or an "LC" filter network can be parallel connected to output end. But it should be noted that the external capacitance of the output terminal cannot be too large, otherwise it may cause startup problems,so please refer to the product's maximum output capacitive loading requirements for details. The bandwidth of the "LC" filter network should be far away from the working frequency range of the product. In general, a low ESR filter capacitor can be connected to the output end to meet the requirement which is usually Co=100uF.

When input power voltage is unstable, please ensure that its output voltage fluctuation range meets the input requirements of the product; the output current of the input power supply must be sufficient to bear the product's instantaneous starting current Ip, generally: Ip =2-4*Iin-max.
