CONTROL FUNCTIONS
Voltage Input Ports
BRICK (BCM) input voltage range should exceeded. internal under over voltage lockout function prevents operation outside normal operating input range. turns within input voltage window bounded "Input undervoltage turn-on" "Input overvoltage turn-off" levels, specified. protected against accidental application reverse input voltage addition rectifier series with positive input, reverse rectifier shunt with positive input located load side input fuse. connection power source should implemented with minimal distribution inductance. interconnect inductance exceeds input should bypassed with damper retain source impedance stable operation. With interconnect inductance damper series with single electrolytic equivalent low-Q capacitor used place series bypass.
+Out -Out Voltage Output Ports
sets contacts provided +Out port. They must connected parallel with interconnect resistance. Similarly, sets contacts provided -Out port. They must connected parallel with interconnect resistance. Within specified operating range, average output voltage defined Level behavioral model Figure current source capability rated specifications section this document. output impedance reduces eliminates need limited life aluminum electrolytic tantalum capacitors input converters. Total load capacitance output should exceed specified maximum. Owing wide bandwidth output impedance BCM, frequency bypass capacitance significant energy storage more densely efficiently provided adding capacitance input BCM.
Primary Control
Primary Control port multifunction node that provides following functions: Enable Disable port left floating, output enabled. Once this port pulled lower than with respect -In, output disabled. This action realized employing relay, opto-coupler, open collector transistor. Refer Figures 1-3, typical enable disable characteristics. This port should toggled rate higher than port should also driven pulled external voltage source.
Primary Auxiliary Supply port source Vdc. port should never used sink current. Alarm contains circuitry that monitors output overload, input overvoltage undervoltage, internal junction temperatures. response abnormal condition monitored parameters, port will toggle. Refer Figure alarm characteristics.

APPLICATION NOTES TEST CIRCUIT
Parallel Operation
will inherently current share when operated array. Arrays used higher power redundancy application. Current sharing accuracy maximized when source load impedance presented each within array equal. recommended method achieve matched impedances dedicate common copper planes within deliver return current array, rather than rely upon traces varying lengths. typical applications current being delivered load larger than that sourced from input, allowing traces utilized input side necessary. dedicated power planes however, preferable. power train control architecture allow bi-directional power transfer, including reverse power processing from output input. Reverse power transfer enabled input within operating range otherwise enabled. BCM's ability process power reverse improves transient response output load dump. Anomalies response source will appear output multiplied factor. resistance source should kept possible minimize voltage deviations. This especially important operated near high line over/under voltage detection circuitry could activated.
Input Fuse Recommendations
BRICKs internally fused order provide flexibility configuring power systems. However, input line fusing BRICKs must always incorporated within power system. fast acting fuse should placed series with port. agency approvals fusing conditions, click link below:
Input Impedance Recommendations
take full advantage capabilities, impedance presented input terminals must from approximately MHz. source should exhibit inductance (less than should have critically damped response. interconnect inductance exceeds input pins should bypassed with damper (e.g., series with retain source impedance stable operations. Given wide bandwidth BCM, source response generally limiting factor overall system response.
