Robert Mammano, a co-founder of Silicon General Semiconductors, develops the first integrated circuit for SMPS control, model SG1524. [15] After a series of mergers and acquisitions (Linfinity, Symetricom, Microsemi), the company is now part of Microchip Technology. [22] 1977 The Apple II is designed with a switched-mode power supply. [23] 1980

Common circuit diagram symbols (US ANSI symbols) An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may ...
Typical use of TL431 in SMPS. Shunt resistor R3 maintains minimum TL431 current, series resistor R4 is part of frequency compensation network (C1R4) [31] [32] In the 21st century, the TL431, loaded with an optocoupler's light-emitting diode (LED), is the de facto industry standard solution for regulated switched-mode power supplies (SMPS).
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...
This number is followed by the letter 'R' to indicate a receptacle (socket) or 'P' to indicate a plug (prongs). As an example, the 5-15R is the common 125 V two-pole, three-wire receptacle rated for 15 A.
The 79xx devices have a similar "part number" to "voltage output" scheme, but their outputs are negative voltage, for example 7905 is −5 V and 7912 is −12 V. The 7905 and/or 7912 were popular in many older ATX power supply designs, [ 4 ] [ 5 ] and some newer ATX power supplies may have a 7912.
