BCM6123TD1E5126T01 Descripción general
What is a BCM (Bus Converter Module)? A BCM is a fixed-ratio, isolated DC-DC converter typically used as a building block inside a Factorized Power Architecture (FPA). It is sandwiched between a high-voltage primary DC bus and a lower-voltage intermediate bus, providing galvanic isolation, voltage transformation, and bidirectional power flow. Within Vicor's product hierarchy it sits alongside PRMs (Pre-Regulator Modules) and VTMs (Voltage Transformation Modules); together they form a complete intermediate-bus solution that decouples the source conversion stage from the downstream point-of-load regulation.
Key features include a K=1/8 fixed transformation ratio, a wide 260-410V input operating window that aligns directly with 3-phase PFC rectified rails, and a robust protection suite covering output over-voltage, over-current, under-voltage, short-circuit, and over-temperature faults. The through-hole ChiP package exposes a substantial thermal interface that allows full output derating only above 70°C ambient with adequate system cooling.
Internally, the BCM6123 employs Vicor's proprietary Sine Amplitude Converter (SAC) topology, driving a custom planar transformer with a soft-switching ZCS/ZVS scheme that keeps switching losses well below those of conventional hard-switched converters. The result is a flat efficiency curve across most of the load range and negligible reverse-recovery stress, which contributes to the 97.9% peak figure.
Typical applications include 380V industrial three-phase intermediate bus architectures, hybrid battery / HV-DC distribution in renewable energy storage and electric vehicle charging stations, and high-density 48V-100V server and telecom backplane feeds. The -T01 device-grade variant supports digital telemetry and PMBus-style telemetry interfaces when used alongside a Vicor upstream controller.
When laying out a board for the BCM6123, keep input and output loops as small as possible and follow Vicor's recommended land pattern; the through-hole ChiP terminations also carry the main current path, so adequate copper weight and thermal vias to inner copper planes are critical for full 1.2 kW operation without thermal throttling.

Aplicaciones típicas
BCM6123TD1E5126T01 es adecuado para 6 aplicacións: 380V Three-Phase Industrial Bus Intermediate Stage, Energy Storage / Battery DC-DC Conversion, EV / HV DC Fast Charging Infrastructure, 48V Server Rack and Telecom Distribution, Renewable / PV String Inverter Conversion, Rail and Industrial Traction Auxiliary Supplies.
380V Three-Phase Industrial Bus Intermediate Stage
The BCM6123TD1E5126T01 accepts 260-410V directly from a three-phase PFC front-end and produces a 47.5V intermediate bus at 25.7A, making it the canonical conversion block in a Vicor FPA tree feeding downstream PRM/VTM or DCM bricks. Its 4242 VDC isolation removes the need for separate safety barriers on the PCB, and the 97.9% peak efficiency keeps chassis dissipation below 30W per module at full 1220W load - allowing dense, fan-cooled subracks. Use the telemetry interface of the T01 variant to feed back input voltage and temperature for predictive maintenance in PLC cabinets.
Recomendado
Energy Storage / Battery DC-DC Conversion
High-voltage battery racks (typically 350-400V nominal) feed the BCM6123TD1E5126T01 directly to produce a 47.5V intermediate bus feeding a battery-management distribution network. With 1876 W/in³ density the BCM6123 ChiP fits alongside contactors and pre-charge hardware in compact 1-2U conversion cassettes. Bidirectional power flow lets the same hardware handle regen back into the pack during regenerative braking, while the wide 260-410V input covers all common state-of-charge extremes without reconfiguration.
Recomendado
EV / HV DC Fast Charging Infrastructure
Inside a 150-350kW DC fast charger, the BCM6123TD1E5126T01 isolates and steps 380V PFC output to 47.5V for the charger-internal sub-distribution that powers cooling pumps, fans, and the communication/contactor board. The 4242 VDC isolation simplifies compliance with IEC 61851, while 97.9% peak efficiency cuts energy waste across the charger fleet. Parallel several ChiPs on a common bus when scaling a single dispenser above 600V/800A. The T01 telemetry allows real-time reporting into the charger's service monitor.
Recomendado
48V Server Rack and Telecom Distribution
For -48V-style data-center distribution that has migrated to higher intermediate voltages, the BCM6123TD1E5126T01 fed from a 380V primary produces a tightly regulated 47.5V intermediate rail for downstream 48V hold-up converters and 12V/3.3V/1.8V buck POLs. The ~1230W capacity aligns with one 1U supply or one blade-server shelf; multiple ChiPs can be paralleled for full 6kW shelves. Match the unit with a Vicor AC-front-end PFC and use the BCM's bidirectional SAC topology to keep ride-through hold-up buses charged.
Recomendado
Renewable / PV String Inverter Conversion
String inverters for utility-scale PV produce intermediate DC in the 600-1500V range, but distributed DC-coupled architectures using lower-voltage PV arrays sit naturally at 380V DC; the BCM6123TD1E5126T01 then steps that intermediate to a usable 47.5V bus for the inverter's gate-drive and aux supply. 97.9% efficiency at the conversion stage adds back several tenths of a percent to overall energy yield over the lifetime of the inverter. The wide 260-410V input also lets the same hardware ride through string mismatch without clipping.
Recomendado
Rail and Industrial Traction Auxiliary Supplies
Onboard train auxiliary converters fed from 600V-750V DC catenary typically include a 380V intermediate; the BCM6123TD1E5126T01 transforms that into 47.5V for door controls, lighting drivers, and HVAC boards. Its 4242 VDC isolation meets IEC 61287-1 surge and dielectric requirements. The ChiP package is ruggedized for shock and vibration per Vicor's industrial-grade qualification, and the -40°C to +125°C operating window supports unheated railway undercar installations.

Notas de diseño
At 1220 W output and 97.9% peak efficiency the worst-case dissipation is about 26 W, but real-world operation at the 380 V/47.5 V point typically lands at 95-97% efficiency so the ChiP sheds 35-60 W into the chassis. Pair the BCM6123 through-hole ChiP with Vicor's reference cold-plate or a thermal interface material rated for >=2 W/m-K and a 200-400 LFM forced-air stream. Add a thermistor in the heatsink's airflow path to monitor the T01 telemetry channel and feed it back for derating.
Use the land pattern supplied in the Vicor BCM6123 ChiP datasheet; deviations invalidate isolation and thermal performance. Recommended: 4 oz copper minimum for the input/output power planes, with thermal vias 0.3 mm diameter spaced 1.0 mm apart under the ChiP base. Keep the high-frequency switching loops - input and output bypass capacitors to the ChiP terminals - within 10 mm to minimize radiated EMI. Pin-compatibility between BCM6123TD1E5126T01 and the BCM6123TD1E5126T00/T440/T263/T135/T115 family lets the same layout accept any of those variants.
Do not parallel the BCM6123TD1E5126T01 with a non-telemetry T00 grade and treat them as identical for safety analyses - the T01 contains firmware-driven fault assertions through the telemetry channel that a T00 device may not honour. Also: never operate this BCM below 260 V input; the under-voltage lockout will force a hard shutdown below that point. Estimate: 97.9% efficiency derives from the manufacturer datasheet figure; calculated mid-load numbers above derive from estimated ratio curves and should be confirmed in-system.
