V•I Chip Voltage Transformation Module
PRELIMINARY
Input Impedance Recommendations
To take full advantage of the VTM’s capabilities, the impedance of the
source (input source plus the PC board impedance) must be low over a
range from DC to 5 MHz. The input of the VTM (factorized bus) should be
locally bypassed with a 8 µF low Q aluminum electrolytic capacitor.
Additional input capacitance may be added to improve transient
performance or compensate for high source impedance. The VTM has
extremely wide bandwidth so the source response to transients is usually
the limiting factor in overall output response of the VTM.
Anomalies in the response of the source will appear at the output of the
VTM, multiplied by its K factor of 1/16. The DC resistance of the source
should be kept as low as possible to minimize voltage deviations on the
input to the VTM. If the VTM is going to be operating close to the high
limit of its input range, make sure input voltage deviations will not trigger
the input overvoltage turn-off threshold.
Input Fuse Recommendations
V•I Chips are not internally fused in order to provide flexibility in
configuring power systems. However, input line fusing of V•I Chips must
always be incorporated within the power system. A fast acting fuse is
required to meet safety agency Conditions of Acceptability. The input line
fuse should be placed in series with the +In port.
Warranty
Vicor products are guaranteed for two years from date of shipment against defects in material or workmanship when in normal use and service. This
warranty does not extend to products subjected to misuse, accident, or improper application or maintenance. Vicor shall not be liable for collateral or
consequential damage. This warranty is extended to the original purchaser only.
