- How to convert between different units of resistivity
Some data sheets specify units of resistivity as Ω sq mil How could I convert that to units of Ω-cm?
- 110 V AC to 5 V DC converter circuit and Eagle schematics
I have a circuit and a microcontroller The circuit take 110 V AC, and I need 5 V DC to power the board The circuit is plugged to a power outlet where it takes its power What I need to do is to p
- How to make a step down DC-DC converter fail safe?
4 I'm planning to power some high power colored LEDs with a buck converter, using a microcontroller to control the switching to maintain a constant current I'm also considering a simpler, switched capacitor converter It seems unlike a step up DC-DC converter, a step down converter has a fail deadly mode of being stuck in the on state
- Transformer calculations for a voltage-fed push-pull converter
Times the volume of the air gap, this gives (most of) the energy stored in a gapped core -- this is the case for ferrite cored inductors (coupled or otherwise) (A flyback transformer might be better described as a coupled inductor, as it stores and releases energy alternately
- Audio using PWM, what is the principle behind it?
PCM with DAC, filter and amplifier This depends on how your DAC is built internally Most sound card DACs will be using sigma-delta modulation, which resembles PWM in that it's a one-bit signal turned on and off at high speed through a filter, but using a smarter algorithm to ensure the correct output level and slew rate This example sound card codec datasheet has a nice diagram on the first
- How do those 3. 5mm stereo to mono adapters work?
I have one of those 3 5mm Female Mini-phone mono to Mini-phone stereo which I was hoping to use for connecting the output of an MP3 player (stereo) to a pillow speaker (mono) But then it occurred
- Speaker level to line level - Electrical Engineering Stack Exchange
I want to reduce my amplifier output to line-level I found this tutorial, Connecting speaker signals to line level inputs, which is compatible with 50 nbsp;W output power There is also mentione
- 230V AC to 5V DC converter, lossless - Electrical Engineering Stack . . .
Is there any IC which converts 230V AC to 5V DC? As lossless as possible I want to connect my microcontroller to an ordinary electrical socket and I don't have enough space available Thanks
