APPLICATION INFORMATION
†
output circuitry
The SG2524 contains two identical npn transistors, the collectors and emitters of which are uncommitted. Each
transistor has antisaturation circuitry that limits the current through that transistor to a maximum of 100 mA for
fast response.
general
There are a wide variety of output configurations possible when considering the application of the SG2524 as
a voltage-regulator control circuit. They can be segregated into three basic categories:
D
Capacitor-diode-coupled voltage multipliers
D
Inductor-capacitor-implemented single-ended circuits
D
Transformer-coupled circuits
Examples of these categories are shown in Figures 9, 10, and 11, respectively. Detailed diagrams of specific
applications are shown in Figures 12–15.
