    Comparison of a linear power supply and a switched-mode power supply Linear power supply Switching power supply Notes Size and weight: 0.12 W/cm 3, 88 W/kg [28] Smaller than linear power supply. Compared to linear, a SMPS that is 20 kHz is 1/4, 100–200 kHz is 1/8, and 200 kHz–1 MHz types can be even smaller. [28]: 5–8

  3. Power supply unit (computer) - Wikipedia

    en.wikipedia.org/wiki/Power_supply_unit_(computer)

    Entry-Level Power Supply Specification (EPS) is a power supply unit meant for high-power-consumption computers and entry-level servers. Developed by the Server System Infrastructure (SSI) forum, a group of companies including Intel, Dell, Hewlett-Packard and others, that works on server standards, the EPS form factor is a derivative of the ATX ...

  4. Switching noise jitter - Wikipedia

    en.wikipedia.org/wiki/Switching_noise_jitter

    When this type of supply bias is used to power a system operating in power-saving modes or pulsed applications as shown in Fig. 1 the current drain fluctuates in pulses. Typically a load enters a high power stage (e.g. RX/TX On) for tens of micro- to milli-seconds and is then switched to low power or standby mode for hundreds of milli- or tens ...

  5. Boost converter - Wikipedia

    en.wikipedia.org/wiki/Boost_converter

    For high efficiency, the switched-mode power supply (SMPS) switch must turn on and off quickly and have low losses. The advent of a commercial semiconductor switch in the 1950s represented a major milestone that made SMPSs such as the boost converter possible. The major DC to DC converters were developed in the early 1960s when semiconductor ...

  7. Power supply - Wikipedia

    en.wikipedia.org/wiki/Power_supply

    An integrated power supply is one that shares a common printed circuit board with its load. An external power supply, AC adapter or power brick, is a power supply located in the load's AC power cord that plugs into a wall outlet; a wall wart is an external supply integrated with the outlet plug itself. These are popular in consumer electronics ...

  8. Sense (electronics) - Wikipedia

    en.wikipedia.org/wiki/Sense_(electronics)

    In electronics, sense is a technique used in power supplies to produce the correct voltage for a load.Although simple batteries naturally maintain a steady voltage (except in cases of large internal impedance), a power supply must use a feedback system to make adjustments based on the difference between its intended output and its actual output.

  9. Off line regulator - Wikipedia

    en.wikipedia.org/wiki/Off_line_regulator

    An off line regulator can be a complete integrated circuit with all capabilities necessary to provide clean power to a small portable or handheld device, or it may be used as part of a larger switched mode power supply (SMPS) or DC-DC converter.
