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. VI-200, VI-J00 Standard Output Voltages Figure 2–1 — VI- / MI-200, VI- / MI-J00 – 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).

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. Daisychaining additional Boosters (connecting GATE OUT of one unit to GATE IN of a succeeding unit) leads to a virtually unlimited power expansion capability.

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.

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. (Figure 7– 4) Rev 3.5 Apps. Eng. 800 927.9474 vicorpower.com 800 735.6200
