Not Recommended for New Designs - Replaced by BCM384x120y300A00  
Pin / Control Functions  
+In / -In – DC Voltage Input Ports  
The V•I Chip input voltage range should not be exceeded. An internal  
under / over voltage lockout-function prevents operation outside of the  
normal operating input range. The BCM 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 V•I Chip 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 V•I Chip 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 2.2 µF in  
series with 0.3. A single electrolytic or equivalent low-Q capacitor may  
be used in place of the series RC bypass.

PC – Primary Control  
Bottom View  
The Primary Control port is a multifunction node that provides the  
following functions:  
Enable / Disable – If the PC port is left floating, the BCM 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. Refer to Figures 1-  
3, 12 and 13 for the typical enable / disable characteristics. This port  
should not be toggled at a rate higher than 1 Hz. The PC port should  
also not be driven by or pulled up to an external voltage source.

Primary Auxiliary Supply – The PC port can source up to 2.4 mA at  
5.0 Vdc. The PC port should never be used to sink current.  
–Out  
Alarm – The BCM 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, the PC port will toggle. Refer to Figure 13  
for PC alarm characteristics.

TM and RSV – Reserved for factory use.  
+Out / -Out – DC Voltage Output Ports  
Two sets of contacts are provided for the +Out port. They must be  
connected in parallel with low interconnect resistance. Similarly, two sets  
of contacts are provided for the –Out port. They must be connected in  
parallel with low interconnect resistance. Within the specified operating  
range, the average output voltage is defined by the Level 1 DC behavioral  
model of Figure 21. The current source capability of the BCM is rated in  
the specifications section of this document.  
The low output impedance of the BCM 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 BCM should not exceed the  
specified maximum. Owing to the wide bandwidth and low output  
impedance of the BCM, low frequency bypass capacitance and  
significant energy storage may be more densely and efficiently provided  
by adding capacitance at the input of the BCM.
