The off-line BCM provides an isolated 10.3 -11.4 V distribution bus and is ideal for use in silver boxes and PFC front ends. Due to the fast response time and low noise of the BCM, 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 BCM achieves a power density of 876 W/in 3 in a V•I Chip package compatible with standardpick-and- place and surface mount assembly processes. The V•I Chip package provides flexible thermal management through its low Junction-to-Case and Junction-to-Board thermal resistance. Owing to its high conversion efficiency and safe operating temperature range, the BCM does not require a discrete heat sink in typical applications. Low junction to case and junction to lead thermal impedances assure low junction temperatures and long life in the harshest environments.

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 µF in series with 0.3Ω. A single electrolytic or equivalent low-Q capacitor may be used in place of the series RC bypass. PC – Primary Control 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. Primar y 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. 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 22. 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. -In PC RSV TM +In -Out +Out -Out +Out Bottom View A B C D E F G H J K L M N P R T 4 3 2 1 A B C D E H J K L M N P R T Figure 14—BCM pin configuration Signal Name Designation +In A1-E1, A2-E2 –In L1-T1, L2-T2 TM H1, H2 RSV J1, J2 PC K1, K2 +Out A3-D3, A4-D4, J3-M3, J4-M4 –Out E3-H3, E4-H4, N3-T3, N4-T4
