Covers linear regulators and the transition to high-efficiency switching regulators. It details pulse-width modulation (PWM), a field Mammano pioneered with the design of the first integrated PWM controller IC (the SG1524) in 1974.

Robert Mammano gave us the PWM controller; then, he gave us the manual to use it. Whether you find the PDF via a Texas Instruments archive, a used bookstore, or a university repository, the knowledge inside remains timeless. In an era of digital logic and software-defined hardware, the laws of inductors and capacitors have not changed. Mammano wrote the map.
