What is the difference between the LT1054 from TI & the LT1054 from Linear Technologies, other than price

The following has me puzzled: The specifications on the datasheets of the LT1054 from Texas Instruments appear the same to me as those of the LT1054 from Linear Technologies. In Europe the TI LT1054's cost half as much or less than the ones from…

What determins the available amps in an AC to DC converters (wall wart)?

Concerning the older, simple transformer, rectifier, capacitor AC to DC converters, what determines available amps (amp output)? Is it simply the thickness of the transformer wires? What about the lighter, smaller, more complex, more modern…

How can I calculate voltage in this circuit?

I know this circuit is called 'Negative Impedance Converter' and for this case, works as -100 ohm resistance. What is the voltage of the lowest bifurcation when I apply triangular wave(0 to 0.1 to 0 V, period 0.1 s)? I thought the current flows…

110 AC to 12 DC with high Watt

I'm looking into purchasing a winch that is powered by 12V DC. It's a 1 horse power winch, so I assume it requires just over 700 Watt to function at max load. Right? I want to use it at home, so I somehow need to convert 110V AC to 12V DC. When I…

Boost converter's voltage stress

I know the answer is Vs=Vo, by simulation. BUT I don't know why. In steady state inductor is gonna be short. And Vs is parallel with Vin and Vout. Can you tell me what is wrong?

Cascade circuit

To power a PA107DP Apex Microtechnology amplifier, I need two power supplies, one of + / -18V and another of + / -100V. To supply it with +/- 100V, I use the R24100B power supply from Recom. In the datasheet I saw the configuration of two cascade…

220V to 12V converter

I need to convert 220 V AC to 12 V DC in my circuit that can provide minimum 100 mA at 12 V DC. It should always be on 24 hours a day and 7 days a week. I don't want to use a transformer because my current should be small. I want to use this to…

5VDC output converter going to 10V when IC is connected

I have a pcb which uses ICs including two MCP3008. The voltage provided by the DC DC converter is to be 5V, and it is 5V when the two MCP3008 ICs are not inserted in the sockets. But when I place either of them in either socket (two ICs, two dip…
