BCM6123T60E15A3T00
Vicor BCM6123T60E15A3T00 fixed-ratio bus converter, 48 V input to isolated 9 to 15 V output, K=1/4 at 130 A with about 98% efficiency.
The BCM6123T60E15A3T00 is a Vicor BCM bus converter, an isolated fixed-ratio DC-DC converter that operates from a 36 to 60 V primary bus and delivers an isolated ratiometric 9 to 15 V secondary with a 1/4 transformation ratio, at up to 130 A and about 1.95 kW. It is a Sine Amplitude Converter (SAC) that runs at high frequency with a low series impedance, giving low noise, fast transient response and about 98 percent peak efficiency, among the best in its class. Because the ratio is fixed, the secondary voltage tracks the primary, and the module behaves as an efficient capacitance multiplier, letting bulk capacitance on the low-voltage bus be scaled down and freeing board space at the point of load. The module provides 4242 VDC isolation and includes under and over-voltage lockout, over-current, short-circuit and over-temperature protection, with an optional PMBus digital interface for control and telemetry. The 6123 ChiP package measures about 63.34 by 22.80 by 7.21 mm and offers low thermal impedance, and the part is rated for the -40 °C to +125 °C T grade. It suits 48 V architectures needing a high-current low-voltage rail, telecom and high-density point-of-load power. Every module BeiLuo ships is factory-traceable and supplied with an import declaration, a certificate of origin and a RoHS compliance file.
FAE Professional Review
The BCM6123T60E15A3T00 is the module we recommend when a design needs a very high-current, low-voltage rail with isolation and best-in-class efficiency. Its 1/4 ratio from a 48 V bus produces a 9 to 15 V secondary at up to 130 A, ideal for feeding point-of-load regulators. Keep the primary and secondary loops tight to exploit the fast transient response.

Frequently Asked Questions
What is the BCM6123T60E15A3T00 best used for?
It is used to deliver a very high-current, low-voltage isolated rail from a 48 V bus, feeding non-isolated point-of-load regulators in telecom and high-density systems. The 1/4 ratio and about 98 percent efficiency make it efficient at high current.
The fast transient response supports dynamic loads.
How do I exploit the fast transient response?
Because the BCM has low series impedance and high bandwidth, it responds quickly to load steps, so the downstream point-of-load regulators see a stiffer bus. Keep the primary and secondary power loops tight and use the recommended filtering to preserve the response.
