Product Overview
• Enterprise networks
The Intermediate Bus Converter (IBC) Module is a very efficient, low profile, isolated, fixed
• Optical access networks
ratio converter for power system applications in enterprise and optical access networks.
• Storage networks
Rated at up to 300 W from 36 Vin to 60 Vin, the IBC conforms to an industry standard
• Automated test equipment
eighth brick footprint. Its leading efficiency enables full load operation at 55°C with
only 200 LFM airflow. Its small cross section facilitates unimpeded airflow — above
and below its thin body — to minimize the temperature rise of downstream components.

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.

EN - Enable/Disable
Negative Logic Option
If the EN port is left floating, the IBC output is disabled. Once this port ispulled 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 7 and 8 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.
Figure 31 — IBC Pin Designations
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. Refer to Figures 7 and 8 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. 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 2000ms. Once the module has been disabled for at
least 2000ms, the turn on delay after the EN pin is enabled will be as
shown in Figure 8.
+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.

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.
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.
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 transient response to an output load dump.
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.
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
overvoltage /undervoltage detection circuitry could be activated.
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.

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

The Sine Amplitude Converter TM (SAC TM) uses a high frequency resonant tank to transfer energy from input to output. The resonant tank is formed by Cr and
leakage inductance from the main transformer, Lr, as shown in the block diagram. The controller regulates switching frequency of the FET drivers, monitors
current sensing, and provides undervoltage and overvoltage protection.
