2. 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 ...

3. Bootstrapping (electronics) - Wikipedia

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

   In switch-mode power supplies, the control circuits are powered from the output. To start the power supply, a leakage resistance can be used to trickle-charge the supply rail for the control circuit to start it oscillating. This approach is less costly and simpler than providing a separate linear power supply just to start the regulator circuit ...

5. 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 ...

6. Linear amplifier - Wikipedia

   en.wikipedia.org/wiki/Linear_amplifier

   A linear amplifier is an electronic circuit whose output is proportional to its input, but capable of delivering more power into a load. The term usually refers to a type of radio-frequency (RF) power amplifier , some of which have output power measured in kilowatts , and are used in amateur radio .

7. Switched-mode power supply - Wikipedia

   en.wikipedia.org/wiki/Switched-mode_power_supply

   In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. The switched-mode power supply's higher electrical efficiency is an important advantage. Switched-mode power supplies can also be substantially smaller and lighter than a linear supply because the transformer can be much smaller.

8. Regulated power supply - Wikipedia

   en.wikipedia.org/wiki/Regulated_power_supply

   A regulated power supply is an embedded circuit; it converts unregulated AC (alternating current) into a constant DC. With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable voltage (or less often current), to a circuit or device that must be operated within certain power supply limits.

9. LM386 - Wikipedia

   en.wikipedia.org/wiki/LM386

   The LM386 is an integrated circuit containing a low-voltage audio power amplifier. [1] It is suitable for battery-powered devices such as radios, guitar amplifiers, and hobby electronics projects. The IC consists of an 8-pin dual in-line package and can output 0.25 to 1 watts of power, depending on the model, using a 9-volt power supply.
