Figure 2 shows a solution to producing a 3.3V backup supply that reserves energy for critical loads using a blocking MOSFET. The blocking diode shown in Figure 1 is replaced by Q1, a low gate ...

The power-on-reset(POR) generates a reset pulse to ensure that the core processing circuits are in a defined state when the power is ramping up or ramping down. The POR detects the safe supply ...

Breadboard Power Supply Offers 3.3V, 5V, And Adjustable 1.2V – 21V. 10:59 am February 6, 2018 By Julian Horsey.

If you are moving your 5V design to 3.3V, the first things to look for are 3.3V versions of the 5V devices. In most cases, you'll find equivalent devices that operate from 3.3V. Usually, 3.3V devices ...

Power Regulator, also called Voltage Regulator, is an on-chip device which converts an external high voltage power supply into suitable power supplies for a core. It is very convenient for a user to ...

A computer power supply converts AC into multiple DC voltages. For example, 12 volts is commonly used for drives, while 3.3v and 5v are used by the chips and other motherboard components.

The design features banana plugs outputting +12V, -12V, +5V, and +3.3V, with all outputs appropriately fused for safety. There’s also a fused stepdown converter used to supply variable voltages ...

Launched as an improvement over the previous AT (Advanced Technology) standard, ATX requires the power supply to produce three DC power outputs; +3.3V, +5V and +12V, and features two major design ...

The PS8710A uses a single 1.5V power supply while the PS8710B uses a single 3.3V power supply. The PS8710A/B are sampling now and production volumes will be available January 2011. Both devices ...

Silverstone has debuted an ultra-high capacity 2500W power supply that has enough juice and connectors to power four 12V-2x6-equipped GPUs. The Hela 2500Rz comes with four 12V-2x6 power connectors ...

Breaking down the power rails shows a very impressive 34A for the 12v rail, 30A for the 5v rail, and 30A for the 3.3v rail. I've seen more than one PSU that claims to be high-end but only offers ...
