Hello,
I need to control a 10V proportional valve using a current control with PWM, i checked some forum related to this topics but no one gave some answer for this. So, i would like you to help me with this. Cutrrently i have this on my board but the manufacturer says that we are controlling...
Ok, thanks for your reply, i will test with 1k.
According with the PWM frequency i did it till 2Khz and the behavior geot better but still the vibrations. The datasheet does not recommend any PWM. :???:

Hello Thanks for your answer.
With this circuit we onlye wan to...
Hello!
I have a pair of these valve:s https://kellypneumatics.com/download_files/MidPVspec.pdf. We tried to control them using a PWM signal from a Raspberry Pi but this is not working causing some vibrations and notable fluctuations on the output. So i decided to write you to help us with a...
Hello,
I'm working on a design which i don't have enough slots to add I/O's to the main connector, so i i'm thinking in the possibility of implement a circuit which lets me manage DIGITAL I/O as a single pin(s) controlled by a microprocessor, is to say, i would like to know if it possible to...
Hello, i need to design a driver to the LCD described on the following image.
I'm using a frequency generator with a 5Vpp TTL signal to activate one segment or word of the LCD and commuting the corresponding COMM's but i have many interference, so...
- I don't know if i'm using this...
Hello,
I have a device as you can see on the image attached that always is always spinning around an axis. It has a reflective surface that i want to use to detect it and count it as a lap. So, i don't know which kind of optical sensor use or which idea could you give me to do this. I hope to...
I need to supply 11V to three solenoids valves, but i dont want to use another Step-down IC because all the components circuit increase the price of the board, so i would like to know what else i could do? What dou you recommend me?
Thanks for your attention and ideas.
Hello!!
You were right, according with the PCB layout suggestions, the C2 must be closer to the IC and i did that and inmediately begins to work as expected. Thanks for that! :-D:-D:-D:clap::clap::clap:
PD: The only thing that i don't know why is not working is that i increase the input...
Hello, thanks for your reply,
Is 100mA maximum.

Hello, thanks for your reply.
Below are the schematics and the corresponding PCB Layout, also the typical application recommended by the manufacturer in the datasheet.
I hope you can help me with this.
Best regards,
Hello!
I'm working with the LT8609EMSE#PBF to supply voltage to Raspberry Pi Zero W mini PC and i'm getting many troubles with this regulator.
If the Vin voltage is 12V the Raspberry works without problems, turns on it Wi-Fi module and never reset itself.
Now, if the Vin voltage increase...
