Product Description
The VI Chip High Current VTM series of DC-DC converters are designed for Building-in. The input to the
VIV00wwxFy is intended to be supplied from a SELV or other non-hazardous secondary circuit.
The High Current VTM model numbers VIZ0026x, VIZ0027x, VIZ0056x, VIZ0057x, VIZ0063x, and VIZ0064x
converters provide Functional Insulation from Input to Output. The output can be considered SELV if the
input is SELV.
The High Current VTM model numbers VIZ0037x, VIZ0038x, VIZ0059x, VIZ0060x, VIV0005xFy,
VIV0007xFy and all VTM2 models provide Basic Insulation from Input to Output with 1500 Vdc of dielectric
withstand.
Customer special model numbers VIZ0026x, VIZ0027x, VIZ0056x, VIZ0057x, VIZ0063x, VIZ0064x are
mounted on an interposer PCB and include additional SELV circuitry.

Engineering Conditions of Acceptability
For use only in or with complete equipment where the acceptability of the combination is determined by UL
LLC. When installed in an end-product, consideration must be given to the following:
The following Production-Line tests are conducted for this product: Electric Strength
The following secondary output circuits are SELV: All
The following secondary output circuits are at non-hazardous energy levels: All
The investigated Pollution Degree is: 2
Input Voltage: Both a nominal input voltage and an input voltage range are specified. Operation over
the entire range was evaluated
Max Temperature: See de-rating curve for1323 VTM3. For VTM1 / VTM2/0623 VTM3. Keep the
maximum semiconductor junction temperature of the VI Chip at 125oC or less. There are 3 methods
to achieve this condition: Method 1: Monitor Case Temp. Keep Tcasemax 100°C or below when
operating the VIV0005TFJ at 130A or less Keep Tcasemax 100°C or below when operating the
VIV0007TFJ at 115A or less Tcasemax is the maximum case temperature of the VI Chip Method 2:
Calculate Keep Tcasemax equal to or below 125°C - ( Pdissmax X 1.5 ) under all conditions where
Pdissmax = PInput_max - POutput_max. Pdissmax is the amount of power in Watts dissipated within
the device. The thermal resistance of the VI Chip from the internal semiconductor junction to the
case is 1.5 oC/W Method 3: Cold plate application Keep Tcasemax 50°C or below when operating
the VIV0005TFJ between 130A and 150A. Keep Tcasemax 50°C or below when operating the
VIV0007TFJ between 115A and 130A. Tcasemax is the maximum case temperature of the VI Chip
Over temperature: If the max. rated temperature is exceeded the unit may be damaged
The VIV00wwxFy series of DC-DC converters are non-isolating. The output can be considered SELV
if the input is SELV.
The VIV00wwxFy series of DC-DC converters provide 2250 Vdc of insulation from Input / Output to
the Case.
Fusing Requirements: VTM1 and VTM2. The High Current VTM and VTM2 series of DC-DC
converters were evaluated with Littelfuse Nano² SMD fuse rated 10A / 125Vdc. The fuse may be
replaced by an external current limiting circuit to be evaluated in the end product. VTM3 overcurrent
protection to be evaluated in the end product.
The VIZ0026x, VIZ0027x, VIZ0056x, VIZ0057x, VIZ0063x, VIZ0064x include a current limiting circuit
on the interposer PCB, external to the VI Chip, and do not require external fusing.
The High Current VTM model numbers VIZ0026x, VIZ0027x, VIZ0056x, VIZ0057x, VIZ0063x,
VIZ0064x, and VTM3 converters provide Functional Insulation from Input to Output. The output can
be considered SELV if the input is SELV.
The High Current VTM model numbers VIZ0037x, VIZ0038x, VIZ0059x, VIZ0060x, VIV0005xFy,
VIV0007xFy and all VTM2 models provide Basic Insulation from Input to Output with 1500 Vdc of
dielectric withstand.
