  2. Switched-mode power supply - Wikipedia

    en.wikipedia.org/wiki/Switched-mode_power_supply

    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. Buck converter - Wikipedia

    en.wikipedia.org/wiki/Buck_converter

    It is a class of switched-mode power supply. Switching converters (such as buck converters) provide much greater power efficiency as DC-to-DC converters than linear regulators, which are simpler circuits that dissipate power as heat, but do not step up output current. [1]

  4. Single-ended primary-inductor converter - Wikipedia

    en.wikipedia.org/wiki/Single-ended_primary...

    Figure 1: Schematic of SEPIC. The single-ended primary-inductor converter (SEPIC) is a type of DC/DC converter that allows the electrical potential at its output to be greater than, less than, or equal to that at its input. The output of the SEPIC is controlled by the duty cycle of the electronic switch (S1).

  5. TL431 - Wikipedia

    en.wikipedia.org/wiki/TL431

    In a typical power supply/charger supplied with a laptop computer, average I CA is set at around 1.5 mA, including a 0.5 mA LED current and a 1 mA shunt current (2012 data). [ 7 ] Design of a robust, efficient and stable SMPS with TL431 is a common but complex task. [ 34 ]

  6. Flyback converter - Wikipedia

    en.wikipedia.org/wiki/Flyback_converter

    Low-power switch-mode power supplies (cell phone charger, standby power supply in PCs) Low-cost multiple-output power supplies (e.g., main PC supplies <250 W [ citation needed ] ) The flyback converter is commonly used at the 50 to 100 W power range, as well as in highvoltage power supplies for televisions and computer monitors - Fundamentals ...

  7. Ćuk converter - Wikipedia

    en.wikipedia.org/wiki/Ćuk_converter

    Its schematic can be seen in figure 1. It is an inverting converter, so the output voltage is negative with respect to the input voltage. The main advantage of this converter is the continuous currents at the input and output of the converter. The main disadvantage is the high current stress on the switch. [4] Fig. 1: Cuk converter circuit diagram.

  8. Buck–boost converter - Wikipedia

    en.wikipedia.org/wiki/Buck–boost_converter

    This is a switched-mode power supply with a similar circuit configuration to the boost converter and the buck converter. The output voltage is adjustable based on the duty cycle of the switching transistor. One possible drawback of this converter is that the switch does not have a terminal at ground; this complicates the driving circuitry.

  9. 78xx - Wikipedia

    en.wikipedia.org/wiki/78xx

    The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. It is a component in switching regulator designs and is not a linear regulator like other 78xx devices. The 7803SR from Datel is a full switching power supply module (designed as a drop-in replacement for 78xx chips), and not a linear regulator like the ...
