Uses Silicon General SG1524 IC as pulse-width-modulated regulator for which operating frequency remains constant, with ON time of each pulse adjusted to maintain desired output voltage. Operating range extends above 100 kHz but device draws only 10 mA. IC includes voltage reference, oscillator, comparator, error amplifier, current limher, pulse-steering flip-flop, and automatic shutdown for overload.-P. Franson, Today's Monolithic Switching Circuits Greatly Simplify Power-Supply Designs, EDN Maga-zine, March 20, 1977, p 47-48, 51, and 53.
