One example wherenegative voltageis used for dual supply operational amplifiers. Many times, these amplifiers deal with AC signals. Therefore, positive and negative rails need to be established; and they are established through the application of positive and negative DC voltages to the o...
The LCD panels usually employs the charge pump to generate the negative voltage due to low cost, but the drawback isobvious: power delivery is limited and regulation is very bad and changes with input voltage since charge pump can onlygenerate the integral times input voltage. In some high-...
Perhaps a new product? This area seems to be a gap in product offerings on the market. I'm looking for a way to eFuse a relatively low voltage negative supply: -3.3V. All of the eFuse options that I see on the market are appropriate for high side switchin...

The source of electricity (whether it is a generator, battery or something else) will want to push electrons out of its negative terminal at a certain voltage. For example, one AA battery typically wants to push electrons out at 1.5 volts. The electrons will need to flow from the negative...
How can this voltage be reduced? It turns out, there are many ways of doing so, and one of the easiest and cheapest ways of doing so is simply using resistors. With resistors, we can form a voltage divider circuit, so that we can obtain any voltage we want. ...
In most cases, the red test lead should be inserted into the terminal labeled “Hz,” and the black test lead should be inserted into the terminal labeled “COM.” Some models can measure voltage and frequency simultaneously, and some require the red test lead to be inserted into the “V...
Step 4: Fine-tune Voltage (Optional) If you’re comfortable and want to push further: Return to BIOS and slightly increase CPU voltage (e.g., by 0.025V). This can help stabilize higher clock speeds but generates more heat. Never exceed the maximum safe voltage for your CPU (research thi...
spec). This applies to voltage controls (adaptive and static) and voltage offset controls. With UVP enabled, negative voltage offsets that result in a voltage level below the boot voltage value will not be recognized or applied, and the processor will remain at the previously programmed voltage...
For many years, mainland Western Europe has used a mains electricity supply rated at nominally 220VAC 50Hz while the UK used 240VAC 50Hz. In 1994, the European Union state members decided to proceed with a voltage harmonisation at 230Vac. This meant that consumers could be sure that a produc...
