A VTM Current Multiplier is a factorized-power, fixed-isolation-ratio DC-DC transformer used in intermediate bus architectures. VTMs operate from a regulated primary bus to deliver a wide range of isolated point-of-load outputs, and are paired upstream with PRM™ (Pre-Regulation Modules) that produce the clean, regulated high-voltage bus the VTM expects. Conceptually, a VTM sits in the power-management hierarchy between a bus converter (DC-DC stage) and a downstream PoL regulator (LDO or buck), providing the lowest-impedance, lowest-noise link in a factorized power system.
Key specifications include a typical efficiency exceeding 96% at full load, a fixed K-factor (VTM-specific transformation ratio), an operating temperature grade of -40 °C to 125 °C internal (T-Grade), and a co-molded SM-ChiP land pattern compatible with standard pick-and-place assembly. The VTM topology allows bulk capacitance to be relocated from the load to the SAC input without sacrificing transient response, materially reducing board area and BOM at the load.
Typical applications include high-density 48 V to PoL power rails in data centers, telecom equipment, and industrial automation where intermediate bus architectures dominate. Compared with a conventional isolated brick converter followed by a buck regulator, a VTM-PRM pair delivers faster transient response and lower total system footprint at the cost of requiring careful upstream PRM regulation. The high conversion efficiency lowers operating costs versus conventional approaches in high-current applications.
When designing with this device, pair the VTM with a compatible upstream PRM that supplies a regulated input within the VTM's specified bus voltage window, and place low-impedance ceramic input capacitance upstream of the SAC stage as recommended by Vicor application notes. Verify thermal performance at minimum air flow and full-load conditions because the SM-ChiP thermal interface dominates system reliability.
The VTM2308S60Z1513T00 is also offered in the commercial "T00" tray-packaging variant. Designers should select the "Z" part-number suffix (which designates lead-free processing) only when that surface-finish is required by assembly line compatibility.

Aplikasi Biasa
VTM2308S60Z1513T00-VICOR patut untuk 6 aplikasis: 48 V Data Center Point-of-Load Rails, Telecom 48 V Isolated Distribution, Industrial Automation Robotics, High-Performance Computing GPU Power, Aerospace/Defense Avionics Power, LED Driver Power Stages.
48 V Data Center Point-of-Load Rails
The VTM2308S60Z1513T00's 26-60 V input range and 12.5 A / 187 W output rating make it ideal for factorized-power data center architectures stepping down a 48 V intermediate bus directly to sub-1.8 V PoL voltages at the processor load. With ZCS/ZVS SAC topology the VTM holds conversion efficiency above 96% at full load, directly reducing rack-level cooling cost. The 2308 SM-ChiP footprint allows dense placement near the load with minimal PCB trace losses. Compared with a 48 V-to-PoL buck regulator alone, a VTM+PRM pair delivers faster transient response (multi-MHz loop bandwidth) to handle large load steps in CPU/GPU power profiles.

Telecom 48 V Isolated Distribution
In telecom equipment using a -48 V nominal bus, the VTM2308S60Z1513T00 pairs with a PRM to deliver isolated, low-voltage rails required by digital signal processors and ASICs in baseband cards. Its isolation rating per the SAC topology provides the galvanic barrier required by telecom safety standards. The SM-ChiP co-molded package offers superior thermal conductivity for fanless or low-airflow chassis. Designers benefit from an extended temperature range of -40 °C to 125 °C internal (T-Grade), compliant with outdoor and central-office equipment profiles.

Industrial Automation Robotics
The VTM2308S60Z1513T00 is well suited to industrial robotics controllers where 24 V or 48 V battery/aux supplies must deliver isolated logic rails to servo amplifiers and DSP controllers. Its surface-mount 2308 SM-ChiP package tolerates typical industrial shock and vibration because the chip-scale land pattern minimizes solder-joint stress. The wide 26-60 V input range handles 24 V industrial bus under-voltage transients without requiring an upstream boost converter. Compared with discrete isolated flyback converters, a VTM+PRM chain simplifies EMI compliance thanks to the sinusoidal SAC switching waveform.

High-Performance Computing GPU Power
In AI accelerator and GPU card designs, the VTM2308S60Z1513T00 is used to drive high-current, low-voltage core rails (e.g., 0.8 V) directly from a 48 V backplane, eliminating intermediate buck stages. The VTM's low AC impedance beyond most regulators' bandwidth means the bulk capacitance normally required at the load can be relocated to the SAC input, freeing board area for signal routing. The 12.5 A / 187 W rating suits mid-range GPU memory and auxiliary rails. Designers value the multi-megahertz SAC switching frequency which minimizes the magnetic footprint and beats conventional 48V-to-PoL buck converters in transient performance.

Aerospace/Defense Avionics Power
The VTM2308S60Z1513T00 in its T-Grade form (-40 °C to 125 °C internal) serves in avionics distributed-power architectures where 28 V or 48 V avionics buses feed isolated digital-signal-processor rails. Co-molded ChiP construction provides the ruggedness and thermal-mass density required in vibration-prone cockpit and pod-mounted electronics. The factorized architecture reduces the number of isolation barriers, lowering total component count and improving MTBF. Compared to legacy isolated bricks, the VTM combination is markedly lighter and shorter, critical for flight platforms with strict weight budgets.

LED Driver Power Stages
In high-brightness LED driver designs for stadium lighting and cinema projection, the VTM2308S60Z1513T00 steps a 48 V supply down to the constant-current driver stage with greater than 96% efficiency. Its isolated topology simplifies user-safety compliance for line-voltage-connected fixtures by removing need for separate isolation barriers. The SM-ChiP small footprint enables dense driver PCB layouts at higher power per square inch. Compared with a discrete flyback plus buck chain, the VTM+PRM combination reduces EMI filter complexity and eliminates audible noise from typical 100 kHz switching converters.

Catatan Desain
The 2308 SM-ChiP co-molded package provides a large thermal interface area. At 187 W full load with 96% efficiency, dissipation is approximately 7.8 W. Vicor recommends attaching a thermal interface material (TIM) or cold plate directly to the bottom thermal pad; avoid relying solely on PCB top-side copper for sustained full-load operation. Maintain the bottom thermal pad unbroken and free of solder mask, and via-array the pad to inner copper planes for lowest junction-to-ambient thermal resistance.
Follow Vicor's recommended SM-ChiP land-pattern geometry: input/output pads must use IPC-7351 SMD land sizes; the bottom thermal pad requires a via-array of 0.3 mm drilled, 0.5 mm pitch, copper-filled and plated. Use low-ESR ceramic input bypass directly upstream of the SAC (within 5 mm) to minimize the AC loop area and limit switching-node ringing. Maintain a clearance between the input and output copper planes per the VTM's isolation rating.
Pair the VTM2308S60Z1513T00 with a compatible upstream PRM that produces a regulated bus within the VTM's 26-60 V input range. Although the SAC topology can be fed by a non-Vicor regulated bus, ensure the bus source has low output impedance at the VTM's multi-MHz switching frequencies - low-ESR ceramic capacitance upstream of the VTM is required. Bulk capacitance normally placed at the load can be relocated upstream of the VTM, but downstream PoL regulators must still see clean ripple at their input.
Do not confuse a VTM with a standalone DC-DC regulator. Attempting to power a VTM from an unregulated 48 V source will pass input variations directly to the output at the VTM's fixed K-factor, violating output regulation. Do not exceed the maximum input voltage (60 V) under transient conditions such as bus load-dump; add TVS protection if the upstream source can overshoot. Do not route high-current traces through the package outline - use thick copper pours directly into the input/output pads.
