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 Apple II is designed with a switching mode power supply.
Low-cost converter modules: two buck and one boost. Boost converter from a TI calculator, generating 9 V from 2.4 V provided by two AA rechargeable cells.. A boost converter or step-up converter is a DC-to-DC converter that increases voltage, while decreasing current, from its input to its output ().
Diagram of a typical XT and AT voltage regulator circuit Internals of a PSU with passive PFC (left) and active PFC (right) The desktop computer power supply converts the alternating current (AC) from a wall socket of mains electricity to a low-voltage direct current (DC) to operate the motherboard, processor and peripheral devices.
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 full explanation is given there.) We note from basic AC circuit theory that our ripple voltage should be roughly sinusoidal: capacitor impedance times ripple current peak-to-peak value, or Δ V = Δ I / (2ω C ) where ω = 2π f , f is the ripple frequency, and f = 1/ T , T the ripple period.
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.
A circuit breaker contains an element that heats, bends and triggers a spring which shuts the circuit down. Once the element cools, and the problem is identified the breaker can be reset and the power restored. Some power supplies use a thermal cutout buried in the transformer rather than a fuse. The advantage is it briefly allows greater ...
