VTM2308S60Z0825T00-VICOR 概述
A VTM is a class of isolated/non-isolated Point-of-Load (PoL) DC-DC transformer module used inside Vicor's Factorized Power Architecture (FPA). Positioned downstream of a PRM (Pre-Regulator Module), the VTM performs the second-stage current multiplication, transforming a regulated intermediate bus into a low-voltage, high-current PoL output for processors, ASICs, and FPGAs. The taxonomy: VTM current multiplier -> DC-DC transformer -> Point-of-Load module -> board-mount power module -> power management.
Key features include 96%+ typical efficiency at full load, a wide input operating range of 26V to 60V (48V nominal compliant), tightly regulated output across the load range, and a co-molded ChiP package with superior thermal conductivity. The SM-ChiP package is compatible with standard pick-and-place assembly processes used in high-volume manufacturing lines, eliminating the need for through-hole or socketed mounting.
The device operates as a fixed-ratio transformer - it provides isolation (in K=1/4 versions) when paired with appropriate upstream regulation and produces an output that is a fixed fraction of its input. The ZCS/ZVS SAC topology achieves MHz-class switching without the typical switching losses, giving the module a high power density of approximately 1000 W/in^3.
Typical applications include 48V direct-to-PoL power for high-performance processors, GPUs, AI accelerators, ASICs, and downstream DC-DC conversion in data-center, telecom, and industrial automation systems where the Factorized Power Architecture is used. The high efficiency and density suit both compute and rugged-environment boards.
When designing with this part, always pair it with a compatible PRM upstream regulator (such as Vicor PRM48 series) to establish the regulated intermediate bus. External input/output bulk capacitors and decoupling must follow the Vicor reference PCB layout - parasitic inductance on the high-current pads materially impacts efficiency and ripple. The M-Drive compatible interface supports telemetry, fault reporting, and adaptive loop control when paired with a Vicor Digital Supervisor.

典型应用
VTM2308S60Z0825T00-VICOR 适用于 6 应用s: 48V Direct-to-PoL CPU/GPU Power, AI Accelerator and ASIC Power, Telecom and Networking Equipment, Industrial Automation and Robotics, Aerospace and Defense Avionics, Data Center and Server Power Distribution.
48V Direct-to-PoL CPU/GPU Power
Deploys the VTM2308S60Z0825T00 in the second stage of a Vicor FPA chain, transforming a regulated 48V intermediate bus from a PRM into a 7.5V/25A Point-of-Load rail feeding a high-performance CPU or GPU core. With 96%+ typical efficiency at full load and SM-ChiP power density above 1000 W/in^3, the module eliminates intermediate 12V bus conversion and cuts distribution losses by ~4x compared with legacy 12V architectures. Placed immediately adjacent to the VRM socket with low-inductance power-plane via arrays; unlike discrete buck converters the VTM requires no output inductors and dissipates under 8W at 188W load.
推荐
AI Accelerator and ASIC Power
Drives the high-current core rails of AI accelerators, networking ASICs, and inference chips that demand 150-200W from a single 0.8-1.0V to 7.5V rail. The VTM2308S60Z0825T00's 25A continuous output at 96% efficiency keeps thermal rise below 8W loss at full load, enabling dense compute board layouts without external heatsinks. It is paired upstream with a PRM to produce a regulated 7.5V core rail for ASICs requiring higher voltage than direct PoL; SM-ChiP co-molded packaging supports AOI-compatible surface-mount lines used by hyperscaler OEMs.
推荐
Telecom and Networking Equipment
Powers low-voltage, high-current rails inside 48V telecom and 5G base-station digital boards where space is constrained and efficiency directly impacts thermal margins. The VTM2308S60Z0825T00's wide 26-60V input range complies with nominal 48V telecom rails and tolerates transient excursions to 60V; co-molded SM-ChiP package with superior thermal conductivity enables fully sealed outdoor enclosure designs. Used alongside -48V bus architecture standards (ETSI EN 300 132-2, ATIS-0600315) typical in telecom equipment rooms.
推荐
Industrial Automation and Robotics
Supplies regulated PoL power for motor drives, machine-vision processors, and FPGA-based industrial controllers running off a 24-48V machine bus. The 26-60V input range of the VTM2308S60Z0825T00 accepts 48V industrial bus rails while delivering isolated 25A at 7.5V to FPGA core and logic rails; SM-ChiP packaging survives pick-and-place assembly lines used by industrial OEMs. The -40C to +125C operating envelope supports factory-floor deployment with derating; co-molded ChiP thermal interface enables conduction-cooled designs without fans.
推荐
Aerospace and Defense Avionics
Powers low-voltage PoL rails inside avionics and ground-vehicle electronic systems where mechanical robustness and small PCB real estate are critical. The VTM2308S60Z0825T00's fixed-ratio isolation transformer architecture meets aerospace/vibration requirements; the SM-ChiP co-molded package resists mechanical shock and thermal cycling. Paired with the vicor mil-spec variant (VTM2308S60Z0825T0M) for extended screening; supports 28V MIL-STD-704 or 48V power-bus architectures common in modern flight-cabin electronics.
推荐
Data Center and Server Power Distribution
Deploys inside high-density compute-server and GPU-server boards as the second-stage current multiplier in a chained FPA, accepting a regulated 48V bus from a rack-level PSU and converting it directly to 7.5V for downstream core rail conversion. The VTM2308S60Z0825T00's 96%+ efficiency at 188W cuts cooling-plant load compared with 12V intermediate architectures, lowering PUE; SM-ChiP packaging enables < 1/3 the PCB area of equivalent discrete converters. Part of the hyperscaler ecosystem shift to 48V rack power (Open Rack V3 / M-CRPS standards).

设计说明
Always pair the VTM2308S60Z0825T00 with a compatible upstream PRM (e.g., PRM48BF480T250A00) holding the 48V intermediate bus within its regulation window. Without a regulating PRM, output voltage will track input. Size the upstream PRM for at least 110% of VTM peak load to maintain regulation margin under transients. Estimated: at 188W full load with 96% efficiency, power dissipation is approximately 7.8W; ensure PCB thermal copper/thermal interface supports this dissipation in worst-case ambient.
The SM-ChiP co-molded package achieves thermal performance by virtue of its large thermal interface area and high-conductivity molding compound. Use the recommended Vicor land pattern with thermal vias to a copper pour underneath the module. Forced-air cooling may be required in fully sealed enclosures where ambient exceeds 85C. Reference Vicor application note AN: VTM Layout Guidelines for pad-array and via-fanout specifics.
Follow the Vicor reference PCB layout exactly - parasitic inductance on high-current input/output paths materially degrades VTM efficiency and increases ripple. Use multiple parallel via arrays to the inner power planes, and keep the input/output pad loops under 1nH equivalent inductance per loop. X7R or X5R multi-layer ceramic capacitors (10uF + 0.1uF in parallel) are typical for the high-frequency SAC bypass; add bulk aluminum-polymer or electrolytic capacitors on the input to handle transient load step response.
