A BCM (Bus Converter Module) is a fixed-ratio, high-isolation DC-DC converter used as a 'DC transformer' in a Factorized Power Architecture (FPA). Rather than regulating to a fixed output voltage, the BCM multiplies or divides the input by a fixed K factor (K = Vout/Vin = 47.5V / 380V ≈ 1:8 step-down), so downstream regulation is performed by a separate PRM (Pre-Regulator Module) or point-of-load converter. This architecture reduces switching losses, allows paralleling for multi-kW arrays, and provides galvanic isolation up to 4,242 VDC - a key advantage in HV battery, traction, and industrial systems.
Key differentiating features include OV/OC/UV/short-circuit and thermal protection built into the analog control interface, parallel operation for multi-kW arrays with automatic current sharing, and a 4,242 VDC isolation barrier that meets the creepage and clearance needs of 380V battery-link rails. The ChiP (Converter housed in Package) form factor integrates the magnetic and capacitive structures inside a single through-hole module, eliminating external magnetics and simplifying PCB layout.
Typical applications include 380V HV battery distribution in electric vehicles and industrial DC links, 48V/54V bus conversion from 380V traction rails, renewable-energy tie-in to higher-voltage DC microgrids, and any high-density point-of-load front-end where 4 kV isolation is mandatory. Designers typically pair the BCM with a Vicor PRM or downstream buck regulator to close the regulation loop.
A key design consideration: BCM outputs are unregulated, so output voltage tracks input. If the upstream 380V link swings between 260V and 410V, the 47.5V output will swing proportionally (47.5 × 260/380 to 47.5 × 410/380 = 32.5V to 51.3V). Closed-loop regulation must therefore be implemented downstream. Thermal derating is also critical at the high end of the input range.

EV Traction Auxiliary HV-DC-DC Stage
The BCM6123TD1E5126T00 is used as the isolated HV-to-LV front-end for EV traction auxiliary rails fed from a 380V battery link. Its 4,242 VDC isolation satisfies the creepage and clearance required by 380V automotive systems, and the 97.9% peak efficiency keeps conduction losses minimal on the traction inverter's auxiliary 48V bus. The ChiP through-hole package drops directly onto a HV bus PCB and parallel operation supports multi-kW arrays for higher-power zonal architectures. Unlike a discrete 380V buck, the integrated ChiP eliminates external magnetics and reduces BOM count for high-volume EV power designs.

Industrial 380V DC Microgrid Tie-In
In 380V industrial DC microgrids the BCM6123TD1E5126T00 provides isolation and step-down to a 47.5V distribution bus, which then feeds downstream POL converters for 24V, 12V or 5V loads. The 1:8 K factor is well-matched to 380V nominal plant DC, and the 4,242 VDC isolation simplifies safety compliance for industrial cabinets. With 25.7A continuous output (≈1.22 kW) and parallel capability for multi-kW arrays, the BCM6123TD1E5126T00 is well-suited to factory robotics, motor drives, and heavy-machinery DC links where HV isolation is mandatory.

Renewable Energy HV Tie-In
Solar or wind inverters with 380V DC bus outputs use the BCM6123TD1E5126T00 to derive an isolated 47.5V rail for battery storage and low-voltage control electronics. The 97.9% peak efficiency minimizes the converter's share of the renewable plant's overall losses, and the 1876 W/in³ power density enables compact inverter cabinets. The 260-410V input range tolerates the wide voltage swing typical of renewable sources, while 4,242 VDC isolation protects downstream battery-management and monitoring circuits from HV faults.

High-Density Server / Datacenter HV Front-End
The BCM6123TD1E5126T00 serves as the isolated HV-to-LV front-end in 380V datacenter distribution architectures (such as 400V HVDC bus designs). Its 97.9% peak efficiency reduces cooling load in dense server racks, and 1876 W/in³ density frees PCB space for downstream 48V VRMs. The ChiP package also parallel-outputs into multi-kW shelves for hyperscale compute power shelves. Downstream regulation is typically handled by a Vicor PRM or buck converter delivering a tightly regulated 48V rail.

Aerospace HV Power Distribution
In aerospace HV distribution systems (more-electric aircraft, eVTOL, UAV propulsion) the BCM6123TD1E5126T00 converts a 380V HV bus down to a 47.5V rail for avionics, actuation and lighting loads. The 4,242 VDC isolation is critical for fault containment, and 1876 W/in³ density minimizes weight and volume - both at a premium in airborne platforms. The wide 260-410V input range accommodates HV battery transients during takeoff/climb, and 97.9% efficiency limits thermal dissipation in sealed avionics bays.

Robotics & Heavy-Machinery HV Link
Industrial robots and heavy machinery increasingly use 380V DC distribution for servo drives and actuators. The BCM6123TD1E5126T00 converts the HV bus to 47.5V for low-voltage control electronics, sensors and safety circuits. The 4,242 VDC isolation prevents ground loops between HV and LV domains, and the through-hole ChiP package survives high-vibration factory environments. With parallel operation supporting multi-kW arrays, a single BCM family can scale from a 1.2 kW robot cell to a 5-10 kW press line.

ڈیزائن نوٹس
Estimated: at 380V nominal input, 47.5V output, and 25.7A load, throughput power is ~1220W. Because the BCM is unregulated, output voltage tracks the input proportionally: at the 260V minimum, output drops to ~32.5V; at the 410V maximum, output rises to ~51.3V. Closed-loop regulation must be provided downstream (PRM or buck regulator) when a tightly regulated rail is required.
At 97.9% peak efficiency, conduction loss is ~26W at 25.7A/47.5V throughput. The ChiP package must be mounted on a heatsink or thermal copper pour sized to Vicor's mechanical drawing; insufficient cooling will trigger the BCM's internal thermal shutdown. Avoid placing heat-sensitive analog circuits within 10mm of the BCM's top surface.
Do not assume the 47.5V output is regulated - it tracks input by K factor. Do not bypass the PRM or downstream regulator 'to save BOM cost', as this will pass HV transients directly to your LV load. Maintain the HV-side creepage and clearance specified in the BCM6123 datasheet around the through-hole pins.
Use Vicor's recommended PCB layout for the BCM6123 ChiP - HV and LV grounds must be kept separate, and the analog control signals should be routed away from the power pads. When paralleling multiple BCMs, keep inter-module signal-trace lengths symmetric to preserve current-share accuracy. The through-hole pin pads are also the primary thermal path; use thermal vias to inner copper planes.
