Figure 17. Load current regulation with soft start
Current regulation is achieved by the integrated opera-
tional amplifier as P1-controller (R7, C5, C6). Inverted
input (Pin 7) of the operational amplifier is directly con-
nected at C3 with load current proportional test signal
(actual value).
Desired value is obtained with the help of potentiometer
at Pin 8.
