V24A6V5T400BL 개요
A DC-DC converter module is a self-contained switching power subsystem that accepts a DC input voltage and produces one or more isolated, regulated DC output voltages. Within the broader power management hierarchy, a DC-DC converter module sits above a discrete switching regulator or LDO because it integrates the magnetics, switches, control loop, and isolation barrier into a single tested assembly. Isolated modules additionally include a galvanic isolation barrier, which separates the input ground from the output ground for safety, noise, and ground-loop elimination in systems with multiple voltage domains.
Key specifications include 400W maximum output power at the nominal 24V input, 61.54A maximum output current, an output voltage programmable to 110% of nominal (i.e. up to approximately 7.15V), and ±0.25% line/load regulation from no load to full load. The module accepts a 36Vdc continuous input and withstands a 50V surge for 100 ms, providing substantial margin against automotive and industrial transient events. Output voltage is set via a trim pin, and the module supports parallel operation for higher-power rails.
Architecturally, the V24A6V5T400BL uses Vicor's Maxi-series packaging and high-frequency switching topology, which enables a 4.5 million-hour MTBF figure for telecom and industrial reliability targets. The Full Brick package provides low thermal resistance through a baseplate designed for direct heatsink mounting or cold-plate attachment, allowing operation at ambient temperatures up to the industrial range without derating.
Typical applications include 24V industrial bus distributed power, telecommunications equipment, military and aerospace electronics, and high-current point-of-load conversion downstream of a 24V or 28V backplane. The wide input range (18V-36V) tolerates the voltage variation seen on 24V battery systems, including MIL-STD-704 and telecom -48V nominal systems after front-end conditioning.
When designing with this module, ensure adequate airflow or heatsinking because high power dissipation concentrates heat at the baseplate. Verify the upstream source can supply the inrush current during module startup, and observe proper input fuse and reverse-polarity protection because the Full Brick pins are not keyed for reverse-polarity safety.

24V Industrial Distributed Power
The V24A6V5T400BL is purpose-built for 24V industrial bus distributed-power architectures. Its 18V-36V input range tolerates the full swing seen on factory 24V battery-backed buses during sags and transients, while the 6.5V/61.54A output (400W) drives downstream POL converters, FPGA core rails, and motor-driver logic stages. The 50V/100ms input surge withstand provides margin against inductive load switching on the same bus, and the ±0.25% regulation keeps ASIC supply tolerances within spec. Mount the Full Brick baseplate to a heatsink or cold plate to maintain junction temperature under continuous industrial ambient. According to the Vicor Maxi datasheet, the module integrates isolation so the 24V bus ground and the 6.5V load ground remain galvanically separated, simplifying ground-loop design in mixed-signal systems.

Telecom Base-Station Power
The V24A6V5T400BL suits telecom base-station power conversion where a stable 6.5V rail is needed at up to 400W from a -48V conditioned bus. The 18V-36V input range aligns with the post-front-end DC voltage commonly produced from telecom battery plants, and the Full Brick's high power density (over 400W in a single module) reduces board area versus discrete switching regulators. Vicor's Maxi series carries the high MTBF figures telecom central-office equipment requires, and the isolated output eliminates ground loops between the battery plant and the digital baseband. The programmable output (10% to 110% of nominal) lets designers fine-tune rail voltage to optimize downstream POL efficiency. The 50V transient withstand protects against load-dump events typical in telecom power distribution.

Military/Aerospace Electronics
The V24A6V5T400BL serves military and aerospace electronics platforms that require 28Vdc MIL-STD-704 input power conversion. The 18V-36V continuous input range plus 50V/100ms surge withstand covers the MIL-STD-704 normal and abnormal transient envelopes, making this Maxi module a drop-in building block for avionic and ground-vehicle power subsystems. The Full Brick package provides a rugged, baseplate-mounted mechanical form factor qualified for high-shock and high-vibration environments, and Vicor's high-frequency topology achieves the high efficiency (>90%) needed to minimize thermal dissipation in sealed enclosures. The isolated output ground-domain separation is critical for safety in systems that bridge 28Vdc power and low-voltage digital or RF signal chains. Military screening variants are available in the Maxi family.

High-Current Point-of-Load Conversion
The V24A6V5T400BL delivers up to 61.54A at 6.5V, making it ideal for high-current point-of-load applications downstream of a 24V backplane. The 400W rating can directly feed a single high-power FPGA or multi-core processor's intermediate rail without paralleling modules. The programmable output allows fine-tuning to the exact voltage required by the load, optimizing efficiency and headroom for the downstream buck regulator. The Maxi Full Brick's low output impedance and tight ±0.25% regulation minimize supply-rail noise on the load, which is critical for ADCs, DACs, and high-speed transceivers. The isolated input ground domain simplifies PCB layout by allowing the 24V return current to remain physically separated from the low-voltage signal return.

Battery-Backed 24V System Power
The V24A6V5T400BL fits 24V battery-backed systems where the input voltage sags below nominal during discharge and rises above nominal during recharge. The 18V-36V input range covers the full depth-of-discharge to charge-voltage envelope of a 24V lead-acid or lithium battery stack, providing regulated 6.5V output throughout the discharge curve. The 400W power rating supports sustained loads during AC-mains loss, while the 50V/100ms surge withstand handles the inductive kick from adjacent relay or solenoid switching. The Maxi Full Brick's isolated output allows safe connection to grounded battery systems while providing a floating 6.5V rail for sensitive electronics. The baseplate-mount Full Brick package dissipates heat efficiently in enclosed battery compartments.

Industrial Motor Control and Drives
The V24A6V5T400BL supplies 24V industrial motor-control and servo-drive subsystems. The 6.5V/61.54A output powers digital logic, gate drivers, and encoder interfaces, while the 24V input connects directly to the industrial backplane without intermediate conversion. The Full Brick's 400W rating handles the inrush and continuous demands of multi-axis servo drives and motor-control I/O. The isolated input/output barrier protects sensitive control electronics from the high dv/dt noise generated by adjacent power-stage switching. The 18V-36V input tolerates the voltage sag during motor-start events on shared industrial buses. Vicor's Maxi series is a proven workhorse in factory automation equipment.

설계 노트
Estimated: at 24V input, 6.5V output, and 61.54A load (400W output), assuming ~90% efficiency, internal dissipation is approximately 44W. The Full Brick baseplate must be mounted to a heatsink or cold plate capable of dissipating this power while keeping the baseplate below its maximum rated temperature. Vicor provides heatsink selection guidance in the Maxi series datasheet; for natural-convection cooling, a finned heatsink of at least 0.5 C/W is typically required at full load. Forced-air cooling with 200 LFM airflow reduces the required heatsink size substantially.
The Vicor Full Brick package requires through-hole mounting with the pins soldered into plated through-holes on the PCB. Input and output power traces must be sized to carry 61.54A continuous (typically 4 oz copper or bus-bar construction). Place input bulk capacitance within 1 inch of the input pins to suppress switching ripple, and use a ground plane on the inner PCB layers stitched with vias around the input and output pin fields to minimize parasitic inductance. The baseplate mounting holes should connect to the chassis ground for EMI and safety bonding.
Do not exceed the 36V continuous input rating - input transients above 50V for more than 100 ms can damage the module. Always fuse the input side with a fast-blow fuse rated for the maximum DC input current. The trim pin should not be left floating if not used - tie it to the appropriate reference per the Maxi datasheet trim circuit to prevent output voltage drift. Remote sense pins (+Sense/-Sense) must be connected or tied locally to the output pins to avoid regulation instability. Reverse-polarity protection is not built into the module and must be added externally if the input can be reversed during maintenance.
