FAE Perspective: DCM Modules
DCM modules excel in applications where you need a simple, efficient DC-DC conversion without regulation. Their fixed-ratio nature makes them ideal for unregulated bus conversion applications. The ZVS technology significantly reduces switching losses, making them particularly effective in high-power, high-density applications. Consider DCM when regulation is handled downstream by other converters.
Frequently Asked Questions
When should I use a DCM vs. a regulated converter?
Use DCM modules when you need efficient DC-DC conversion without regulation. They're ideal for bus conversion where downstream converters handle regulation.
What are the thermal management considerations for DCM modules?
DCM modules generate less heat due to high efficiency, but proper thermal management is still critical. Use appropriate heat sinking and consider the thermal resistance from junction to case.
Can DCM modules be paralleled for higher power?
Yes, DCM modules can be paralleled for higher power applications, but ensure proper current sharing through careful design of the power distribution network.
BCM™ Module (Bus Converter Module)
BCM (Bus Converter Module) modules are non-isolated, fixed-ratio converters that provide high-current, high-efficiency power conversion. These modules are designed for applications requiring current multiplication with minimal voltage transformation.
Key Features:
- Non-isolated design for high efficiency
- Current multiplication capabilities
- Fixed-ratio conversion (typically 1:1)
- High power density

FAE Perspective: BCM Modules
BCM modules are exceptional for applications needing current multiplication, such as 48V to 12V conversion in data center applications. Their non-isolated design contributes to the extremely high efficiency, while the VIA package provides excellent thermal performance. The fixed-ratio transformation maintains the dynamic response of the downstream converter, which is beneficial in fast-transient applications.
Frequently Asked Questions
What makes BCM modules different from other converters?
BCM modules are unique in their fixed-ratio, non-isolated design with current multiplication capability. They maintain the dynamic response of downstream converters.
How do I handle the non-isolated nature of BCM modules?
Non-isolated means input and output share a common ground. Ensure your system design accounts for this when implementing multiple power domains.
Can BCM modules be used in parallel?
Yes, BCM modules can be paralleled for higher current applications, with natural current sharing due to their inherent characteristics.

FAE Perspective: PRM Modules
PRM modules are designed for Factorized Power Architecture (FPA), where they provide stable, regulated power to VTM modules. The predictable regulation characteristics make them ideal for applications where precise voltage control is necessary. When combined with VTMs in an FPA configuration, they enable excellent power density and efficiency for distributed power systems.
Frequently Asked Questions
What is Factorized Power Architecture (FPA)?
FPA separates voltage regulation from current multiplication, using PRMs for regulation and VTMs for current multiplication, achieving both high efficiency and high current density.
How do PRM and VTM modules work together?
PRMs provide regulated voltage to the input of VTMs, which then provide current multiplication while maintaining voltage transformation, enabling FPA benefits.
What applications benefit most from PRM modules?
Applications requiring regulated output with high power density, such as advanced computing, industrial equipment, and automotive systems.
VTM™ Module (Vicor Transformer Module)
VTM (Vicor Transformer Module) modules are current multiplication devices that provide voltage transformation and isolation. They work with PRM modules in Factorized Power Architecture (FPA) to deliver exceptional power density and efficiency.

FAE Perspective: VTM Modules
VTMs perform current multiplication with voltage transformation, making them ideal for applications requiring high output current at lower voltage. When paired with PRMs in an FPA configuration, they enable remarkable power density by separating voltage regulation from current delivery. The high efficiency and isolation make them suitable for safety-critical applications.
Frequently Asked Questions
How do VTMs provide current multiplication?
VTMs use a fixed turns ratio to transform voltage while inversely transforming current, effectively multiplying current while stepping down voltage.
What are the advantages of using VTM modules?
VTMs provide high current density, galvanic isolation, and exceptional efficiency, especially when combined with PRMs in FPA systems.
Can VTMs be used without PRM modules?
VTMs can be used independently, but their full benefits are realized when used with PRMs in Factorized Power Architecture configurations.
