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 50C 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.

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 F in series with 0.3 . A single electrolytic or equivalent low-Q capacitor may be used in place of the series RC bypass. 2 Top View 3 4 Pin 1 2 3 4 5 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 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. 5 1 Figure 30 -- 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. 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 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.

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 F in series with 0.3 ) 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 overvoltage /undervoltage detection circuitry could be activated. 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. 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 130C, it is recommended that PCB temperatures be maintained at or below 125C. For maximum long term reliability, lower PCB temperatures are recommended for continuous operation, however, short periods of operation at 125C will not negatively impact performance or reliability. 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.
