Data Sheet
When propagation is enabled, the faulty POL converter pulls its OK pin low. A low OK line initiates turn-
off of other POL converters in the group and signals the DPM to pull other OK lines low to initiate turn-
off of other POL converters as programmed.
The regular turn-off of a POL converter means that the output voltage is ramping down according to its
turn-off delay and falling slew rate settings. If a POL converter triggers an undervoltage or
overtemperature fault, it will initiate the regular turn-off. In the case of an overcurrent or tracking fault,
the POL converter initiates the fast turn-off by opening both high and low side switches instantaneously.
If either output overvoltage or phase voltage errors are triggered, the faulty POL converter initiates the
fast turn-off and turns on its low side switch. In addition, when an error is propagated, the DPM can
generate commands to turn off a front end (a DC-DC converter generating the intermediate bus voltage)
and trigger an optional crowbar protection to accelerate removal of the intermediate bus voltage (IBV).
Once the fault has recovered in the faulty POL converter, the other POL converters will turn on in a
controlled manner according to their turn-on delay and rising slew rate settings.
10.5.2 Margining
Margining can be executed separately for each group by clicking an appropriate radio button in the GUI
IBS monitoring window shown in Figure 11 or directly via the I 2 C bus by the margining command. All
POL converters in a group are margined in the same direction (up or down) by the percentage
programmed individually for each POL converter.
10.5.3 Turn-ON and Turn-Off
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 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 2 C bus by specific
commands.
10.5.4 Interrupt Configurations
The DPM has four interrupt inputs that can be programmed to:
?
?
Inhibit the operation of one or several Groups of POL converters when pulled low or
Act as a Group Reprogramming Trigger.
The two functions are mutually exclusive – an interrupt can be either programmed as an Inhibit or as a
Group Reprogramming Trigger.
The interrupts are programmed in the GUI Interrupt Configuration window shown in Figure 18 or directly
via the I 2 C bus by specific commands. In Figure 18 the Interrupt 0 is programmed as the inhibit for
group A and the Interrupt 2 is programmed as the group C reprogramming trigger.
10.5.4.1 Group Inhibit
An interrupt input can be programmed to act as an inhibit on a single or multiple groups of POL converters. When
the interrupt input is pulled low, the DPM will pull the appropriate OK lines low. The affected POL converters will
execute regular turn-off ramping their output voltages down according to the turn-off delay and falling slew rate
settings. Once the interrupt is released, the POL converters will automatically turn-on according to their
turn-on delay and rising slew rates settings.
