- apple-didnt-revolutionize-power.html quote "21. ... This long article on switching power supplies was featured on the cover of Electronics World. The article is worth looking up, if only for the picture of the F‑111 aircraft’s switching power supply, which looks so complex that I’d almost expect it to land the plane. The switching power supplies discussed in this article combine a switching DC‑DC inverter with a transformer for isolation with a separate buck or boost switching regulator. As a result, the article claims that switching power supplies will always be more expensive than linear power supplies because of the two stages. Modern power supplies, however, combine both stages. The article discusses a variety of power supplies including the 250W switching power supply used by the Honeywell H316R. The article says that the switching regulator power supply had come of age because of new advances in high‑speed and high‑power transistors. The cover shows a 500W switching power supply that according to the article could not have been built with the transistors available just a year and a half earlier. ...".

The IBM 5100 was a 50‑pound portable computer that used BASIC and APL, and included a monitor and tape drive. The power supply is described on page 4‑61 as a small, high power, high frequency transistor switching regulator supply that provides 5V, ‑5V, 8.5V, 12V, and ‑12V. ...".

It holds 5 switching regulators to provide multiple voltages, and provides about 700 W. The power supply uses a large transformer to reduce the line voltage to 25V DC, which is passed to the individual switching regulators, which use a buck topology to obtain the desired voltage .".
