AN126 Applications using the SG3524
... resetting a soft start circuit. In the conventional single-ended regulator circuit shown in Figure 2, the two outputs of the SG3524 are connected in parallel for effective 0.0 – 90% duty cycle modulation. The use of an output inductor requires an RC phase compensation network for loop stabllity. ...

12v battery charger - Kaushik Science Projects
... Usually, DC voltages are required to operate various electronic equipment and these voltages are 5V, 9V or 12V. But these voltages cannot be obtained directly. Thus the a.c input available at the mains supply i.e., 230V is to be brought down to the required voltage level. This is done by a transform ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
