d)
REG6/7/8 FSW:
program the internal FSW2 that serve as switching frequency for
regulator 6, 7 and 8.
e)
5/8 channel enable button
:
This buttons allows the configuration for either the
MC34704B (8 channel) or the MC34704B (5 channel) Evaluation Kit.
•
Group B
f)
REGx DVS:
dynamic voltage scaling to modify the output voltage on each regulator
up to +-20%.
g)
REGx over/under voltage response:
setting the “Set flag on OV/UV” or “Sdown on
OV/UV” option allows to turn on a fault flag only or completely shutdown the GRPB
respectively when an over voltage or under voltage is present on one of the Regulator
that belong to this group.
•
Group A
h)
REG1 DVS:
dynamic voltage scaling to modify the output voltage on each regulator
up to +-20%.
i)
REG1 over/under voltage response:
setting the “Set flag on OV/UV” or “Sdown on
OV/UV” option allows to turn on a fault flag only or shutdown the GRPA respectively
when an over voltage or under voltage is present on REG1.
j)
REG1 ON/OFF button:
turns on/off regulator 1.
•
Group C/E
k)
REGx DVS:
dynamic voltage scaling to modify the output voltage on each regulator
up to +-20%.
l)
REGx Soft Start:
Allows to independently control the soft start for each one of the
regulators included in this group.
m)
REGx over/under voltage response:
setting the “Set flag on OV/UV” or “Sdown on
OV/UV” option allows to turn on a fault flag only or completely shutdown the Group
E/C, respectively, when an over voltage or under voltage is present on one of the
Regulator that belong to this group.
n)
Group E ON/OFF button:
turns on/off REG5 when its set to turn on independently.
o)
Group C ON/OFF button:
If REG5 is set to turn on independently, this button only
controls the on/off state of REG6 and REG7. If REG5 is set to turn on together with
REG6 and 7, this button control the on/off state of all three regulators following the
previously set power on sequence.
•
Group D
p)
REG8 DVS:
dynamic voltage scaling to modify the output voltage on REG8 up to
+-20% when voltage mode control is set.
q)
REG8 Soft Start:
Allows to independently control the soft start for REG8.
r)
REG8 control mode:
when set to “Volt” it uses a standard voltage divider to set the
output voltage. when set to “Curr” it uses Rsens at the end of a LED string to set the
desired current flowing through the LED string.
