dcdc module power supply application range

The power supply of the dcdc module is mainly used in power systems such as wireless network, telecommunications/data communications, power systems, industrial control systems, measurement instruments and instruments, and intelligent fields. It is suitable for designs such as large fluctuations in the input range, small power isolation, and small layout space, and to achieve modular product functions to improve product reliability.

Typical Applications

Single output

Notes on using:

Input power supply requires that
the input end of the product must be connected with a low impedance voltage source. If the voltage source impedance is too high or the connection line between the voltage source and the input end of the product is too long, the product will be instable. Connecting a low ESR capacitor to the input end of the product (as close as possible to the input pin of the product) can effectively solve the occurrence of this problem. For example, a 24V input product can be connected to a 22μF capacitor.

② Reduce output ripple
If further reduction of output ripple is required, a suitable filter capacitor can be connected in parallel at the output end or connected to a "LC" filter network. It should be noted that the external capacitor at the output end cannot be too large, otherwise it may cause startup problems. Please refer to the product's *** output capacitive load requirements for details. The bandwidth of the "LC" filter network should be far from the product's operating frequency range. Generally speaking, connecting a low ESR filter capacitor to the output end can meet the requirements, usually Co=100uF.

③ Input current
When the input power supply 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 cope with the instantaneous start current Ip of the product, generally: Ip = 2-4*Iin-max.

④This  product cannot be used in parallel and does not support hot plugging.
