Product Description
The BC384R120T060VM-00 contains two high efficiency, narrow input range Sine Amplitude Converter (SAC) converters operating from a 360 to 400 Vdc primary bus to deliver an isolated low voltage secondary. The module provides an isolated 11.3 -12.5 V distribution bus and is packaged in a thermally efficient VI BRICK BCM Array package. Due to the fast response time and low noise, the need for limited life aluminum electrolytic or tantalum capacitors at the input of POL converters is reduced--or eliminated--resulting in savings of board area, materials and total system cost. The BC384R120T060VM-00 achieves a power density of 268 W/in3 in a VI BRICK BCM Array package utilizing an integrated heat sink. Owing to its high conversion efficiency and safe operating temperature range, the VI BRICK BCM Array does not require additional heat sinking or high airflow velocities. Low junction-to-heat sink thermal impedance assures low junction temperatures and long life in the harshest environments.

Figure 1 - Typical thermal curve - verify all thermal management systems experimentally.
CNTRL - Enable / Disable
The Enable / Disable signal is a multifunction node that provides the following functions: Enable / Disable - If CNTRL is left floating, the module output is enabled. Once this port is pulled lower than 2.4 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 signal should not be toggled at a rate higher than 1 Hz. CNTRL should also not be driven by or pulled up to an external voltage source. Primary Auxiliary Supply - CNTRL can source up to 2.4 mA at 5.0 Vdc. CNTRL should never be used to sink current. Alarm - The module contains circuitry that monitors output overload, input over voltage or under voltage, and internal junction temperatures. In response to an abnormal condition in any of the monitored parameters, CNTRL will toggle.

+In / -In - DC Voltage Input Ports
The BCM Array input voltage range should not be exceeded. An internal under / over voltage lockout-function prevents operation outside of the normal operating input range. The module turns on within an input voltage window bounded by the "Input undervoltage turn-on" and "Input over-voltage turn-off" levels, as specified. The module 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.
+Out / -Out - DC Voltage Output Ports
Multiple pins are provided for the +Out and -Out connections. They must be connected in parallel with low interconnect resistance. reduces or eliminates the need for limited life aluminum electrolytic or tantalum capacitors at the input of POL converters. Total load capacitance at the output of the device should not exceed the specified maximum. Owing to the wide bandwidth and low output impedance of the BCM Array, low frequency bypass capacitance and significant energy storage may be more densely and efficiently provided by adding capacitance at the input.
