Product Overview
The Intermediate Bus Converter (IBC) Module is a very efficient, low profile, isolated, fixed
ratio converter for power system applications in enterprise and optical access networks.
Rated at up to 500 W from 36 Vin and up to 750 W from 54 to 60 Vin, the IBC
conforms to an industry standard quarter-brick footprint while supplying power greatly
exceeding competitive quarter-bricks. Its leading efficiency enables full load operation
at 50°C with only 400 LFM airflow. Its small cross section facilitates unimpeded airflow
— above and below its thin body — to minimize the temperature rise of downstream
components. A baseplate option is available for alternative cooling schemes.
Applications
• Enterprise networks
• Optical access networks
• Storage networks
• Automated test equipment

PIN / CONTROL FUNCTIONS
+In / -In – DC Voltage Input Pins
The IBC input voltage range should not be exceeded. An internal
undervoltage/overvoltage lockout function prevents operation outside of
the normal operating input range. The IBC turns on within an input voltage
window bounded by the “Input under-voltage turn-on” and “Input
over-voltage turn-off” levels, as specified. The IBC may be protected against
accidental application of a reverse input voltage by the addition of a
rectifier in series with the positive input, or a reverse rectifier in shunt with
the positive input located on the load side of the input fuse.

The connection of the IBC to its power source should be implemented with
minimal distribution inductance. If the interconnect inductance exceeds
100 nH, the input should be bypassed with a RC damper to retain low
source impedance and stable operation. With an interconnect inductance
of 200 nH, the RC damper may be 47 µF in series with 0.3 Ω. A single
electrolytic or equivalent low-Q capacitor may be used in place of the series
RC bypass.

If the EN port is left floating, the IBC output is disabled. Once this port is-
pulled lower than 0.8 Vdc with respect to –In, the output is enabled. The
EN port can be driven by a relay, opto-coupler, or open collector transistor.
Refer to Figures 6 and 7 for the typical enable / disable characteristics. This
port should not be toggled at a rate higher than 1 Hz. The EN port should
also not be driven by or pulled up to an external voltage source.

Positive Logic Option
If the EN port is left floating, the IBC output is enabled. Once this port is
pulled lower than 1.4 Vdc with respect to –In, the output is disabled. This
action can be realized by employing a relay, opto-coupler, or open collector
transistor. This port should not be toggled at a rate higher than 1 Hz.
The EN port should also not be driven by or pulled up to an external volt-
age source. The EN port can source up to 2 mA at 5 Vdc. The EN port
should never be used to sink current.
If the IBC is disabled using the EN pin, the module will attempt to restart
approximately every 250ms. Once the module has been disabled for at least
250ms, the turn on delay after the EN pin is enabled will be as shown in
Figure 7.
+Out / -Out – DC Voltage Output Pins
Total load capacitance at the output of the IBC should not exceed the
specified maximum. Owing to the wide bandwidth and low output
impedance of the IBC, low frequency bypass capacitance and significant
energy storage may be more densely and efficiently provided by adding
capacitance at the input of the IBC.

APPLICATIONS NOTE
Parallel Operation
Input Impedance Recommendations
The IBC will inherently current share when operated in an array. Arrays may
be used for higher power or redundancy in an application. Current sharing
accuracy is maximized when the source and load impedance presented to
each IBC within an array are equal. The recommended method to achieve
matched impedances is to dedicate common copper planes within the PCB
to deliver and return the current to the array, rather than rely upon traces
of varying lengths. In typical applications the current being delivered to the
load is larger than that sourced from the input, allowing narrower traces to
be utilized on the input side if necessary. The use of dedicated power
planes is, however, preferable.
To take full advantage of the IBC capabilities, the impedance presented to
its input terminals must be low from DC to approximately 5 MHz.
The source should exhibit low inductance and should have a critically
damped response. If the interconnect inductance is excessive, the IBC input
pins should be bypassed with an RC damper (e.g., 47 µF in series with
0.3 Ω) to retain low source impedance and proper operation. Given the
wide bandwidth of the IBC, the source response is generally the limiting
factor in the overall system response.
Anomalies in the response of the source will appear at the output of the
IBC multiplied by its K factor. The DC resistance of the source should be
kept as low as possible to minimize voltage deviations. This is especially
important if the IBC is operated near low or high line as the
One or more IBCs in an array may be disabled without adversely affecting
operation or reliability as long as the load does not exceed the rated power
of the enabled IBCs.
overvoltage/undervoltage detection circuitry could be activated.
The IBC power train and control architecture allow bi-directional power
transfer, including reverse power processing from the IBC output to its
input. The IBC’s ability to process power in reverse improves the IBC tran-
sient response to an output load dump.
Input Fuse Recommendations
The IBC is not internally fused in order to provide flexibility in configuring
power systems. However, input line fusing of VI Bricks must always be
incorporated within the power system. A fast acting fuse should be placed
in series with the +In port. See safety agency approvals.
Thermal Considerations
The temperature distribution of the VI Brick can vary significantly
with its input/output operating conditions, thermal management and
environmental conditions. Although the PCB is UL rated to 130°C, it is
recommended that PCB temperatures be maintained at or below 125°C.
For maximum long term reliability, lower PCB temperatures are
recommended for continuous operation, however, short periods of
operation at 125°C will not negatively impact performance or reliability.
Application Notes
For IBC and VI Brick application notes on soldering, thermal management,
board layout, and system design visit vicorpower.com.
WARNING: Thermal and voltage hazards. The IBC can operate with surface
temperatures and operating voltages that may be hazardous to personnel.
Ensure that adequate protection is in place to avoid inadvertent contact.
