DCM3623T75X1380T00 Overview
A DCM (DC-DC Converter Module) is an isolated, regulated switching power converter that combines a Zero-Voltage Switching (ZVS) topology with planar magnetic structures to deliver high efficiency in a small footprint. Within the broader power management hierarchy, DCM modules sit between discrete switching regulators (lower density, lower isolation) and full custom power supplies, serving as the building block for distributed power architectures in industrial, aerospace, and defense applications where isolation, density, and time-to-market all matter.
Key differentiating features of the DCM3623T75X1380T00 include its ZVS high-frequency switching architecture, which minimizes switching losses and EMI, and its wide 9-75 Vdc input range that supports 12 V, 24 V, 28 V, 36 V, and 48 V nominal system buses without derating. The 2250 Vdc isolation rating meets the reinforced insulation requirements of industrial IEC 60950-style end equipment. Planar magnetic construction eliminates wire-wound transformer variability and supports automated SMT-style processing despite the through-hole pin format.
The internal architecture uses a ZVS primary-side controller with a proprietary Sine Amplitude Converter (SAC) topology, secondary-side rectification, and a closed-loop feedback path that regulates the 12 V output across line and load. The wide-input range is achieved through Vicor's Factorized Power Architecture (FPA), in which the upstream PI controller can pre-regulate bulk DC and the downstream DCM provides point-of-load isolation and voltage transformation.
Typical applications include industrial 24 V and 48 V bus distributed power, railway and rail-transit auxiliary power, defense and aerospace ground vehicles, test and measurement instrumentation, and any SELV-isolated load requiring 12 V at up to 6.7 A from a wide input bus.
A key design consideration is thermal management: at 90.4% peak efficiency the module dissipates roughly 8.6 W at full 80 W output, so adequate chassis airflow or cold-plate contact is required for continuous operation at 125°C junction temperature.

Typical Applications
DCM3623T75X1380T00 is suitable for 7 applications: Industrial 24V/48V Bus Distributed Power, Railway and Rail-Transit Auxiliary Power, Defense and Aerospace Ground Vehicles, Test and Measurement Instrumentation, LED Driver and Industrial Lighting Control, Distributed Power Architecture (DPA) Building Block, Automotive Auxiliary and SELV Subsystems.
Industrial 24V/48V Bus Distributed Power
The DCM3623T75X1380T00 is purpose-built for 24 V and 48 V industrial distribution rails, accepting 9-75 Vdc and producing an isolated, regulated 12 V at 6.7 A (80 W). Its 2250 Vdc isolation lets it feed SELV-isolated secondary circuitry directly, eliminating intermediate isolation stages. Vicor's ZVS topology achieves 90.4% peak efficiency, so chassis thermal design is straightforward. Compared with discrete 24-to-12 V buck designs, the DCM delivers far higher power density (220 W/in³) and inherent isolation, reducing PCB area and BOM count for factory automation, PLC, and motor-drive auxiliary rails.
Recommended
Railway and Rail-Transit Auxiliary Power
Railway on-board and trackside systems often use 24 V, 36 V, 48 V, 72 V, and 110 V nominal bus rails that vary widely with load dump. The DCM3623T75X1380T00's 9-75 Vdc input window handles these buses directly while the 2250 Vdc isolation satisfies reinforced insulation requirements for EN 50155-style rail end equipment. At 80 W it powers doors, lighting, sensors, and on-board telemetry from a single SELV-isolated 12 V rail. The 9-pin ChiP through-hole package withstands the shock, vibration, and -40°C to +125°C thermal environment typical of rail installations.
Recommended
Defense and Aerospace Ground Vehicles
Military ground vehicles run on 28 Vdc nominal buses with significant transients. The DCM3623T75X1380T00 accepts the full 9-75 Vdc envelope and provides an isolated 12 V at 6.7 A (80 W) for radios, vetronics displays, sensor payloads, and mission computers. The 2250 Vdc isolation and wide -40°C to +125°C operating range meet MIL-style environmental specs for vetronics. Its 220 W/in³ density shrinks power-converter footprint, freeing volume for sensors and batteries; planar magnetics improve reliability versus wire-wound converters.
Recommended
Test and Measurement Instrumentation
Bench-top and rack-mount test equipment requires clean, isolated low-voltage rails (often 12 V) from varied AC-derived or 24/48 Vdc inputs. The DCM3623T75X1380T00 produces a regulated, isolated 12 V at up to 6.7 A from 9-75 Vdc, ideal for powering analog front-ends, DAC/ADC boards, and FPGA co-processors. Its 2250 Vdc isolation protects sensitive measurement paths from ground loops in stacked instruments. The ZVS topology generates minimal EMI, easing compliance with EN 55011/CISPR 11 lab-radiated limits.
Recommended
LED Driver and Industrial Lighting Control
Architectural and industrial LED drivers benefit from isolated, regulated 12 V auxiliary rails to power LED controllers, fans, and control MCUs. The DCM3623T75X1380T00's 80 W capacity handles a controller cluster plus cooling, and the SELV-rated 12 Vout lets designers wire directly to user-accessible controls. Its wide-input tolerance accommodates long-rail 24 Vdc drops and 48 V industrial buses without re-design. The 90.4% peak efficiency and planar-magnetic ChiP construction lower operating temperature versus discrete flyback LED supplies.
Recommended
Distributed Power Architecture (DPA) Building Block
Vicor's DCM family is the canonical building block for Factorized Power Architectures, where an upstream PI controller pre-regulates bulk DC and a downstream DCM isolates and steps down to point-of-load voltages. The DCM3623T75X1380T00 occupies the downstream slot, transforming the pre-regulated bus into an isolated 12 V at 6.7 A. This architecture scales from a single DCM to array N (parallel) or array M (redundant) configurations. Compared with traditional full-brick or intermediate-bus converters, FPA with DCMs achieves higher density and faster transient response.
Recommended
Automotive Auxiliary and SELV Subsystems
Automotive 12 V and 24 V (truck/bus) systems require isolated SELV rails for infotainment, ADAS sensors, and body controllers. The DCM3623T75X1380T00's 9-75 V window covers 12 V and 24 V nominal buses with load-dump margin, and its 2250 Vdc isolation protects downstream electronics from transients. The automotive-grade -40°C to +125°C range supports under-hood and chassis mounting. Compared with discrete flyback designs, the DCM's ZVS topology reduces EMI and improves efficiency at the wide VIN/VOUT ratios typical of automotive 24 V to 12 V conversion.

Design Notes
At 80 W output and 90.4% peak efficiency, internal dissipation is approximately 8.6 W (estimated: Pdiss = Pout × (1/η − 1) = 80 × (1/0.904 − 1)). The ChiP through-hole package conducts heat into the host PCB copper; design at least 2-3 sq. in. of 2 oz copper on input and output pin landings. In sealed enclosures above 60°C, derate to 50-60 W or add forced-air cooling to maintain junction below 125°C.
Place input bulk capacitance (typically 4.7-22 µF ceramic per datasheet) within 5 mm of the VIN+ and VIN- pins to suppress ZVS ringing. Output capacitance (typically 22-100 µF ceramic + bulk) must be within 10 mm of +VOUT and GND. Use a star-ground layout so input and output return currents do not share a single trace; otherwise loop inductance degrades ZVS behavior and increases conducted EMI.
Do not apply input voltage above 75 Vdc - the device has no over-voltage clamping and will damage. Confirm the upstream source is current-limited or fused. Do not load the trim (TR) pin with external resistors without consulting the datasheet trim equations; out-of-range trim values can saturate the internal feedback loop. Finally, respect the isolation barrier: do not place any conductor (trace, via, component) within the 4 mm clearance specified in the datasheet, or 2250 Vdc isolation is compromised.
