BCM48BF030T210A00 Обзор
A bus converter module (BCM) is a fixed-ratio isolated DC-DC converter used in a two-stage distributed power architecture. It sits upstream of one or more point-of-load (PoL) regulators and performs only bus-voltage transformation (no output regulation). This isolates noise, simplifies PoL design, and enables a Factorized Power Architecture (FPA). The BCM's SAC topology is a proprietary soft-switching technique using a small, high-frequency AC transformer and resonant tank to deliver efficiency and density well beyond what hard-switched converters can achieve at the same power level.
Key features include 48 V nominal input (38-55 VDC range), 3.0 VDC nominal output (2.4-3.4 VDC regulated envelope), 210 W continuous output power, >94% peak efficiency, 36-55 VDC input overvoltage/undervoltage lockout thresholds, 1500 VDC input-to-output isolation, and -40C to +125C operating junction temperature. The co-molded VI Chip surface-mount package is compatible with standard pick-and-place assembly and provides an enhanced thermal interface for cold-plate or PCB copper cooling.
The SAC engine delivers sub-milliohm output impedance at high frequency, so bulk output capacitors normally required at the load can be moved to the input side of the BCM. This shrinks the converter's effective footprint at the point-of-load and reduces the design's overall BOM count. The fixed K=1/16 ratio means a 48 V bus becomes a 3 V intermediate bus, which pairs naturally with 1 V or lower PoL regulators in processor and ASIC power trees.
Typical applications include 48 V-to-PoL data center power trees (with downstream Vicor PRM and VTM/ZVS regulators), telecom and network equipment using 48 V backplanes, high-performance computing and AI accelerator boards, RF amplifier power rails in wireless base stations, and industrial 24/48 V bus systems feeding downstream buck regulators. The 3 V intermediate bus is sized to drive 0.8-1.8 V core rails for ASICs, FPGAs, and processors.
When designing with this BCM, observe the derating envelope near 55 VDC input and 70 A output. The VI Chip package requires both top and bottom thermal pads connected to a copper heat spreader or cold plate; relying on the PCB copper pour alone is generally insufficient for sustained 210 W operation. Provide input fusing per Vicor application notes and parallel BCMs only with the manufacturer-recommended current-share interface.

Типичное применение
BCM48BF030T210A00 подходит для 6 применениеs: 48V-to-PoL Data Center Power Tree, Telecom and Network Equipment 48V Backplane, AI Accelerator and HPC Board Power, RF Power Amplifier Rail in Wireless Base Station, Industrial 24/48V Bus System, Aerospace and Defense Avionics.
48V-to-PoL Data Center Power Tree
The BCM48BF030T210A00 sits between a 48V backplane and downstream 1V PoL regulators feeding an ASIC or GPU core rail. Its 3.0V ratiometric output pairs naturally with a downstream VTM or ZVS buck regulator to deliver sub-1V core voltages at >85% system efficiency. The SAC topology holds output impedance below 1 milliohm beyond the bandwidth of most regulators, so output bulk capacitance normally required at the load can be moved to the BCM input - shrinking the footprint at the GPU socket by 30-50%.

Telecom and Network Equipment 48V Backplane
In telecom switches and routers using a -48V backplane (rectified to 48-55V), the BCM48BF030T210A00 provides isolated 3.0V intermediate bus voltage for line-card circuitry. The 1500 VDC isolation is required for telecom network isolation and safety compliance, and the >94% efficiency reduces thermal load in sealed enclosures. The 210W power level comfortably drives a multi-rail line card with PoL regulators for 3.3V, 1.8V, 1.0V, and 0.8V rails from the same 3.0V intermediate bus.

AI Accelerator and HPC Board Power
AI accelerator boards (GPU, TPU, custom ASIC) draw 200-600W per device from sub-1V rails. The BCM48BF030T210A00 generates the 3.0V intermediate bus that feeds multiple VTM current multipliers to deliver up to 200A per phase at 0.8-1.0V. Because the BCM is ratiometric, the actual core voltage tracks the 48V backplane - a 2% droop on the backplane translates to 2% on the core rail, which is acceptable for most ASIC tolerance envelopes. Multiple BCMs in parallel scale linearly to 420W or 630W per rail.

RF Power Amplifier Rail in Wireless Base Station
The BCM48BF030T210A00 converts the 48V station battery rail to an isolated 3.0V rail for RF power amplifier driver stages in 4G/5G base stations. The 1500 VDC isolation provides a clean ground reference for RF circuitry, while the SAC topology's sub-milliohm output impedance rejects ripple that would otherwise couple into the PA bias line as AM noise. The >94% efficiency at 210W keeps system thermal design simple even in sealed outdoor enclosures at 85C ambient.
Рекомендуется
Industrial 24/48V Bus System
Industrial PLCs and motor drives running off a 24V or 48V plant bus use the BCM48BF030T210A00 to derive an isolated 3.0V rail for sensor signal conditioning and ADC reference supplies. The wide 38-55V input tolerates the +/-20% variation typical of industrial bus distribution. The 1500 VDC isolation barrier provides the reinforced isolation required for IEC 61800 motor-drive applications, and the -40C to +125C operating range covers outdoor cabinet deployment.
Рекомендуется
Aerospace and Defense Avionics
In avionics power distribution running off a 28 V or 48 V aircraft bus, the BCM48BF030T210A00 provides an isolated 3.0V rail for mission computer subsystems. Vicor markets MIL-STD-704 and DO-160 compliant variants of the BCM48BF030 family for these applications. The fixed-ratio topology eliminates the loop-bandwidth concerns of regulated converters in EMI-sensitive environments, and the 1500 VDC isolation barrier meets avionics safety isolation requirements.

Заметки по проектированию
The VI Chip package relies on both top and bottom thermal pads connected to copper or a cold plate. At 210 W continuous with >94% efficiency, dissipation is approximately 12-13 W internally. Estimated: at 25C ambient with a 1 square inch bottom copper pour and no top cold plate, junction-to-ambient thermal resistance is about 8-10 C/W; with a top cold plate at 60C the junction rise is roughly 50-65C above cold-plate temperature. For sustained 210 W operation a top cold plate or heatsink is mandatory; PCB copper alone is only acceptable below 100 W.
Vicor specifies a recommended PCB footprint with perimeter land pads and large central thermal vias. Use 0.6 mm via pitch with 0.3 mm drilled holes filled with thermally-conductive epoxy. Solder paste stencil aperture should be 0.10-0.13 mm thick to ensure both the J-lead perimeter and the central thermal pad solder correctly. Do not autoroute power traces through the thermal pad area - they will be cut by the via array.
The BCM48BF030T210A00 is a fixed-ratio bus converter, NOT a regulated output. The output voltage tracks one-sixteenth of the input - if your 48 V backplane droops to 44 V, the output falls to 2.75 V. Downstream regulators must tolerate this input range. Do not load-share two BCMs without the manufacturer-recommended current-share interface; their output impedances are too low for natural current sharing and one unit will hog the load.
Input fusing is required. Vicor recommends a slow-blow fuse sized for 1.5x the BCM's maximum input current (approximately 5.5 A at 48 V), placed within 5 cm of the input terminal. For 48 V telecom applications, a 10 A 250 V slow-blow fuse is typical. The BCM's SAC topology provides controlled inrush, but the fuse protects against external PCB faults such as a downstream regulator short.
