10.3.3
Automatic turn–on upon application of the input voltage is enabled by checking the Auto Turn-On bit in the GUI
Group Configuration window shown in Figure 9 or directly via the I
Configuration Register GxC register shown in Figure 10.
Turn-on and turn-off of various groups during the operation is controlled from the GUI IBS Monitoring window or
directly via the I
according to their tracking and sequencing settings. If the Emergency Turn Off command is used the POL
converters will perform the fast turn-off. In this case, the POL converters will immediately turn off both switches
and output voltages will decay depending on load parameters.
10.3.4
The DPM has four interrupt inputs that allow temporary turn-off of POL groups by pulling the interrupts inputs low.
The interrupts are enabled in the GUI Interrupt Configuration window shown in Figure 18 or directly via the I
by writing into the Interrupt Configuration registers IC1 and IC2 shown in Figure 19.
