DCM3623T50M13C2M00 Overview
An isolated DC-DC converter is a power supply module that uses a transformer to provide galvanic isolation between input and output while stepping up or stepping down the voltage. Within the broader power management hierarchy, isolated converters sit between discrete switching regulators and full AC-DC power supplies; they are essential where the load requires noise isolation, voltage level shifting, or safety-grade separation between high-voltage input rails and low-voltage digital or analog circuitry.
Key features include 12V fixed-output rating, 320W maximum output power, 26.67A maximum load current, 16V-50V wide input range, and built-in analog control interface per the M-grade option. The ChiP package integrates magnetics, switching elements, and control into a low-profile surface/through-hole assembly. High efficiency (typically ~93% at full load) reduces thermal stress and eliminates external heatsinks in many systems.
The DCM3623T50M13C2M00 uses Vicor's proprietary ZVS topology operating at MHz-class switching frequencies with planar magnetics embedded inside the ChiP. This architecture enables the wide 16V-50V input range while keeping the BOM minimal - one module replaces dozens of discrete components normally required for an isolated brick-style supply. The MIL-grade temperature rating makes this specific part suitable for harsh-environment applications including aerospace, military C4ISR, and heavy industrial systems.
Typical applications include 28V bus distribution in military vehicles, avionics intermediate bus conversion, industrial 24V/36V/48V motor drive isolation, and telecom/datacenter intermediate bus architectures. The wide input range supports operation across nominal 24V, 28V, and 48V supply rails without reconfiguration.
When designing with this part, ensure adequate thermal copper area on the host PCB since the ChiP's pins serve as both electrical and thermal conduits. The analog control interface allows trim, enable, and remote sense; designers should preserve the enable pull-up and decouple the trim pin according to the reference design. For higher power or parallel operation, Vicor's proprietary current-share loop can combine multiple DCM units.

Typical Applications
DCM3623T50M13C2M00 is suitable for 7 applications: Military 28V Vehicle Bus Power, Avionics Intermediate Bus Conversion, Industrial 24V/48V Motor Drive Isolation, Datacenter 48V Intermediate Bus, Battery Energy Storage System Power, UAV and Drone Avionics, Naval and Shipboard Electronics.
Military 28V Vehicle Bus Power
The DCM3623T50M13C2M00 is purpose-built for 28V military vehicle power buses (per MIL-STD-1275) where a regulated 12V isolated rail is required to power radio heads, computing payloads, and sensor electronics. Its 16V-50V input window absorbs surge, spike, and cranking transients typical of armored vehicles, while the Military -55C to +125C temperature grade supports engine-bay mounting and arctic operational envelopes. The integrated 3 kV isolation between input and output also lets designers meet chassis-ground isolation requirements without external coupling capacitors. At 320W the module can supply the full auxiliary power budget of a vehicle-mounted mission computer.

Avionics Intermediate Bus Conversion
In avionics architectures the DCM3623T50M13C2M00 converts a 28V or 48V aircraft bus to a clean isolated 12V rail for digital signal processors, RF transceivers, and flight-control actuators. Vicor's ZVS topology produces <50 mV peak-to-peak output ripple under load, eliminating LC filtering stages typically required around discrete brick converters. The ChiP's 0.5-inch by 1-inch footprint frees up board area for redundant channel paralleling, common in DO-178C / DO-254 qualified flight systems. Vicor's heritage in flight-qualified Vicor ChiP modules supports DO-160 environmental qualification by the integrator.
Recommended
Industrial 24V/48V Motor Drive Isolation
Factory automation drives using 24V or 48V supplies typically require an isolated low-voltage rail for control logic, gate drivers, and encoder feedback isolation. The DCM3623T50M13C2M00 supplies 320W of isolated 12V with reinforced insulation, allowing single-board integration of drive power and logic power without violating creepage/clearance requirements per IEC 61800. The wide 16V-50V input tolerates rectified 480V-to-48V industrial bus droop and regen transients, increasing system uptime.
Recommended
Datacenter 48V Intermediate Bus
Modern hyperscale servers are migrating from 12V to 48V distribution to reduce copper losses; the DCM3623T50M13C2M00 takes that 48V bus and produces an isolated 12V rail usable by legacy CPU VR stages and downstream point-of-load converters. Vicor's MHz-class ZVS switching rejects common-mode noise that would otherwise couple from the 48V bus into sensitive analog channels. Two units in parallel can drive 640W to a single motherboard VR stage, simplifying redundancy.
Recommended
Battery Energy Storage System Power
In battery-management systems, the DCM3623T50M13C2M00 converts a 24V or 48V battery stack to a regulated 12V rail for battery-monitoring ICs, contactors, and isolation monitoring. Its 16V-50V input tracks battery voltage through full charge-discharge cycles, while the 320W output supports an entire rack of monitoring nodes. Galvanic isolation prevents ground-loop faults between stacked battery modules.
Recommended
UAV and Drone Avionics
Unmanned aerial vehicles commonly use 6S to 14S LiPo packs (22V-50V) where the DCM3623T50M13C2M00 steps down to a regulated 12V for flight controllers, camera gimbals, and radio modems. The 320W output can also drive auxiliary payload subsystems in higher-end UAVs. With Military-grade temperature tolerance, the module survives high-altitude cold soak and direct-sunload thermal stress on the airframe.
Recommended
Naval and Shipboard Electronics
Shipboard DC distribution runs at 24V, 28V, or 115V and experiences large load-dump transients. The DCM3623T50M13C2M00 with its 16V-50V input window and MIL-STD-1275-grade transient tolerance provides an isolated 12V rail for combat-system computing, sonar processing, and navigation electronics. Conformal coating and salt-fog testing at the integrator level is supported by Vicor's ChiP packaging baseline.

Key Differentiators
- Military-grade -55°C to +125°C operating range (vs DCM3623T50M13C2T00)
- Pin-compatible across temperature grades (vs DCM3623T50M13C2C00)
- Wide 16V-50V input window covers 24V/28V/48V buses (vs Discrete brick converters)
Design Notes
The DCM3623T50M13C2M00 dissipates ~7% of output power as heat at peak efficiency (estimated: 320W × 7% ≈ 22W worst case at low-line input). Host PCB copper area directly under the ChiP ground pad should be at least 4 square inches with 2 oz copper; without adequate copper the module will derate. Vicor's reference design specifies 1 oz copper minimum but recommends 2 oz for full 320W output at 70°C ambient.
Estimated: Despite the wide 16V-50V input range, the DCM3623T50M13C2M00 requires external fusing on the input line; without it, a downstream short can exceed the module's internal protection and damage host wiring. Vicor's reference design uses a 30A fast-blow fuse per module. Also, the analog TM (temperature monitor) pin must be tied to GND through 100kΩ if not used, or the module will report a fault to the host controller. Finally, do not reflow-solder this ChiP variant (M grade); per the datasheet, only wave-solder or socket mounting is supported.
Place the input bulk capacitor (typically 4.7µF to 22µF X7R 100V) within 0.5 inches of the VIN pins to suppress input ripple. Keep the +VOUT output capacitor (typically 100µF X7R 25V) within 1 inch of the output pins; longer traces degrade load-step response. Both ground returns should fan out to a single point on the host PCB to avoid ground-loop noise injection. Estimated: a 50mil trace between capacitor and pin adds roughly 5 nH of parasitic inductance.
Compliance Information
Military-grade DCM modules are commonly built lead-containing solder variants for aerospace/defense programs; RoHS compliance should be confirmed per specific lot. AEC-Q100 does not apply as this is a board-mount module, not an automotive semiconductor IC.
