i was using smps 24v ,1A for that am getting noise how to reduce noise?
i connected dc to dc coverter lm2596 for that also am getting noise.... what to do?Hello,
Also in some datasheets there are optional filters given in the example schematics.
Here is one taken from the LM2596 datasheet:

i have lm2596 dc to dc converter i connected that to the output of smps.....Hello,
I don't quite understand you.
How are things connected?
Can you post a diagram?
Did you implement the extra filter given?

as u told lm2596 buck regulator like that i have lm2596 dc to dc converter i connected that to the smps output.....
for that also am getting noise...

thank youHello,
A smps is a switching powersupply that will give you much more noise than a linear powersupply.
If you feed either of them to a DC-DC converter, you will introduce noise again, as a DC-DC converter is most likely a switching powersupply too.

i was using smps for the given block diagram am getting noise i have to reduce noise..

am using two power supply's linear and smps was using for timer circuit only.Hello,
You have three times an 24 Volts supply in your drawing.

Are those all from the 24 Volts smps?
Is 800 mV disturbing the 24 Volts valve?
