FUNCTIONALITY (CONTINUED)
4.2.2
The system default configuration is to get the 15V, 3.3V and 3.3V analog rail voltages
from the PFC stage board. However, it is also possible to use an external 24V power
supply to generate these voltages.
U19, C70, C73, C71 and C74 regulate the voltage applied to the system via J15 (28V
max). The output of the regulator is connected to the system through R109. The circuit
is shown in
U18, C67, R110, C68, D16, D15, L3, R111, R112 and C75 regulate the 15 volts to cre-
ate a 3.3V digital rail. This auxiliary 3.3V digital rail is applied to the system through
R106. The circuit is shown in
