Overview
Dimensioning Information on External Components
The input capacitor C
I
is recommended for compensation of line influences. The output capacitor C
Q
is necessary
for the stability of the control loop.
Circuit Description
The control amplifier compares a reference voltage to a voltage that is proportional to the output voltage and drives
the base of the series transistor via a buffer. Saturation control as a function of the load current prevents any
oversaturation of the power element. The component also has a number of internal circuits for protection against:
• Overload
• Overtemperature
• Reverse polarity
