With SMPS all over the place, there are tons of options for AC/DC conversion.
Anyone in the biz have any insight into exactly how stable some of the over-the-counter supplies are?
First, you see a lot of wall wart style SMPS supplies. For this particular project, I am looking for something in the 12V range, but there are a slew for the 5V regime. Do these, as a general rule, provide clean power? Realizing they generally do nothing but charge a battery, I'm wondering if a filter may be in order to actively supply say a sensor array or mcu.
Next, you see the laptop style supply. These seem to be often less noisy, and provide more power that their wall-wart counterparts. Do these, as a general rule, provide more stable power as well?
I've used all of these for various projects with good luck. I suppose now I"m curious how well they may work for applications that require a little more precision.
ETA: Yes, I just realized the title is ridiculous. If a mod wants to change to "Consumer SMPS Stability" I would be appreciative.
