Typical Application

Single output

Dual output

Attention in Operation:
1.Input Power Requirements
The input terminal of the product must be connected to a low impedance voltage source. If the impedance of the voltage source is too high or the connection line between the voltage source and the input terminal of the product is too long, the product will be unstable. Connecting a low ESR capacitor to the input terminal of the product (as close as possible to the input pin of product) can effectively solve this problem. For example, a 24V input product can be connected to a 22μF capacitor.
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.
3.Input Current
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.
4.This product cannot be used in parallel or hot-plugging.
