Easiest way to Regulating 12V-16V to 12V?
If you want to simplify your life, just remove one battery, then you are between 9 and 12.6 V, which should be just fine.
If you are planning on doing PWM (control) (ie speed control) anyway, and this …

Is it possible to draw 12V from both halves of a 24V battery pack?
As far as I know, it's not possible to supply a single 12 V load from both sides without a converter of some kind.
The solutions I can see:
use 2 strictly identical loads (in practice there will stil …

Device to restart one computer using another
If the power button performs a graceful shutdown, then in means that the CPU is not completely frozen (maybe the graphic card is, or the mining process, or ...) but not the CPU itself.
So you might tr …

Difference between 5 V supply and 5 V output
Based on the (very limited) schematics you provided, I see 2 possible explanations for the 10V_out :
either it is a real output of the PCB (ie to power some external PCB/component), in which case the …

Is it possible to build consumer-ready, non-PC modular power supplies for generic external d...
I'm not going to answer directly your question (I don't know such a product, but haven't searched for it either), but I will explain why, in my opinion, designing such a product seems complicated :

Reduce number of device power supplies
In an ideal world, no problem.
In practice, there are several points to check before doing so:
Does your 3 devices need to be insulated from each other (if there is no connection at all between the d …

When/why to use a power source selection switch?
Can you guarantee at 100% that there the battery will always be disconnected when the USB is plugged in?
If not, some users will plug both at once (even if you write a warning in big red letters direc …

How is it possible to supply an LM833D with +12V and -8V supply?
Why shouldn't it be possible?
The Op'amp only cares about the voltage between it's 2 supply pins (and that the voltages at input and outputs pins are within the allowed limits compared to the supply p …

Can I power a circuit from the balance cable of a lipo battery?
You say that you care about weight an complexity.
If you do like you planned, your 3.3V circuit will draw its energy from a single cell of the Lipo. Whats more, according to your drawing, you accept a …

In aircraft power supply, why is the neutral not connected to chassis GND unlike household u...
As far as I get from your question and the other answers, in aircraft, neutral is not connected to chassis ground. This is called IT (at least in French), i.e. isolated earth (=terre in French).
So bo …

Power Supply of op-amp
Indeed, supplying an op-amp (or nearlly anything else) with a voltage dividor is a bad idea, and is very probably the cause of your problem (to be 100% sure, we would need to check the resistors used …

Power Supply Concept; Safety and Completeness - Feedback needed
On the safety aspects, I will let the experts answer.
A few elements for you to consider :
it is useless to have a high frequency transformer if you feed it directly from mains (ie at 50 or 60 Hz). I …

What are the reasons or concerns with using an LED power supply to power a motor?
The main difference is that a motor is an inductive load.
In particular, this means that when your PWM is "off", the current will try to keep flowing in the motor: if it has nowhere to go, voltage wil …

Can I increase my power output from my solar panel using a capacitor?
If you want 2W permanent output then of course it is impossible (it would be free energy.)
If, as I understand from your comments, you want to charge your capacitor over a "long" time, and then discha …

Possible fixes to a power supply thermals issue
What you can try :
add a fan blowing on your FET
add a heat sink on top of your FET (can be combined with fan)
if the PCB itself is hot (at least under the FET), then IF PLANE FOR IS NOTHING BUT GROU …
