– IN, + IN. DC voltage inputs. See Tables 2–1 and 2–2 for
nominal input voltages and ranges for the VI-/MI-200 and
VI-/MI-J00 Family converter modules (data sheets contain
Low Line, 75% Max. Power and Transient ratings).
GATE OUT. The pulsed signal at the GATE OUT pin of a
regulating Driver module is used to synchronously drive
the GATE IN pin of a companion Booster module to effect
power sharing between the Driver and the Booster. Daisy-
chaining additional Boosters (connecting GATE OUT of
one unit to GATE IN of a succeeding unit) leads to a
virtually unlimited power expansion capability.
GATE IN. The GATE IN pin on a Driver module may be
used as a logic Enable / Disable input. When GATE IN is
pulled low (<0.65 V @ 6 mA, referenced to –Vin), the
module is turned off; when GATE IN is floating (open
collector), the module is turned on. The open circuit
voltage of the GATE IN pin is less than 10 V.
–OUT, +OUT. DC output pins. See the Table 2–3 and 2–4
below for output voltages and power levels of VI-/MI-200
and VI-/MI-J00 Family converter modules.
Special output voltages from 1 – 95 V; consult factory.
T (TRIM). Provides fixed or variable adjustment of the
module output.
Trimming Down. Allows output voltage of the module to
be trimmed down, with a decrease in efficiency. Ripple as
a percent of output voltage goes up and input range
widens since input voltage dropout (loss of regulation)
moves down.
Trimming Up. Reverses the above effects.
–S, +S (–SENSE, +SENSE). Provides for locating the point
of optimal voltage regulation external to the converter.
Output OVP in VI- / MI-200 will trip if remote sense
compensates output voltage measured at output pins
above 110% of nominal. Discrete wire used for sense
must be tightly twisted pair. Do not exceed 0.25 V drop in
negative return; if the voltage drop exceeds 0.25 V in the
negative return path, the current limit setpoint will increase.
Connect +SENSE to +OUT and –SENSE to –OUT at the
module if remote sensing is not desired.
