VTM48MP010T107AA1 Overview
A VTM current multiplier is a transformer-like isolated DC-DC converter stage used in factorized power architectures. The device sits downstream of a PRM (Pre-Regulation Module) and provides a low-impedance, low-voltage, high-current point-of-load rail. Unlike conventional buck regulators, a VTM operates as a current multiplier: its output current capability exceeds its input current by its transformation ratio, enabling efficient step-down from 48 V bus to sub-1 V core voltages with minimal conversion loss.
Key specifications include 107 A continuous output current, 0.95 V nominal output voltage, 45.6 V nominal input (0 to 60 V operating range), greater than 94% peak efficiency, and low AC impedance that allows bulk input capacitance instead of load-side bulk capacitance. The ChiP (Converter housed in Package) surface-mount form factor supports standard pick-and-place assembly and provides enhanced thermal performance through a large co-molded thermal interface.
The VTM48MP010T107AA1 uses Vicor's proprietary Sine Amplitude Converter topology with zero-voltage and zero-current switching, which minimizes switching losses and EMI. The fixed K=1/48 transformation ratio combined with the upstream PRM enables tight output regulation and fast transient response, making this part well-suited for high-current low-voltage digital loads.
Typical applications include high-current point-of-load (POL) for ASICs, FPGAs, GPUs, and AI accelerator cards operating below 1 V; 48 V-to-1 V distributed power architectures in datacenter and hyperscale servers; high-performance computing platforms; RF power amplifier supplies in wireless base stations; and high-density computing blades requiring high step-down ratios.
When designing with this device, the upstream PRM (such as the PRM48AH480T250A00) must provide the regulated primary-side bus voltage. Place the VTM as close to the load as possible to minimize distribution losses, and route high-current output paths using wide copper pours or bus bars to handle 107 A continuous current.

Typical Applications
VTM48MP010T107AA1 is suitable for 6 applications: High-Current Point-of-Load (POL) for AI Accelerators, 48V-to-1V Datacenter Distributed Power Architecture, High-Performance Computing (HPC) and FPGA Core Power, RF Power Amplifier Supplies in Wireless Base Stations, High-Density Computing Blade Systems, Industrial High-Power Computing and Test Equipment.
High-Current Point-of-Load (POL) for AI Accelerators
The VTM48MP010T107AA1 is ideally suited for powering sub-1V AI accelerator ASICs and GPUs that demand 80 to 107 A continuous current. With its 0.95 V nominal output, greater than 94% peak efficiency, and 1/48 K-factor transformation ratio, the part minimizes power loss when stepping down from a 48 V intermediate bus. When paired with a Vicor PRM48AH upstream regulator, the combined factorized power system delivers fast transient response — critical for AI training workloads where load steps can exceed 50 A in microseconds — while the VTM's low AC impedance allows bulk input capacitance instead of load-side bulk capacitance.

Design Notes
The VTM48MP010T107AA1 in the 1323 ChiP package dissipates approximately 6 to 8 W at full 107 A load (at greater than 94% efficiency). The ChiP's co-molded thermal interface requires a properly sized PCB thermal land with thermal vias to an internal copper plane. Estimated: at 7 W dissipation with the ChiP's typical theta_JA of approximately 8 C/W, junction temperature rises 56 C above ambient. For continuous 107 A operation in ambient temperatures above 70 C, forced-air cooling or a heatsink attached to the top of the ChiP is recommended to keep Tj below 125 C.
Route the high-current 107 A output paths using wide copper pours (minimum 10 mm wide 2 oz copper per 50 A) or dedicated bus bars. According to Vicor's VTM datasheet, the input and output power pads of the 1323 ChiP are designed for direct PCB mounting with thermal vias. Place the input capacitors close to VIN+/VIN- pads and output capacitors close to VOUT+/VOUT- to minimize parasitic inductance, which is critical given the high di/dt at 107 A switching transitions.
The VTM48MP010T107AA1 must NEVER be operated without an upstream PRM providing a regulated primary-side voltage. Unlike standalone buck regulators, a VTM is a current multiplier and will pass through the primary bus voltage scaled by 1/48 if the PRM is missing or unregulated. Per the Vicor datasheet, the upstream PRM (such as PRM48AH480T250A00) handles output regulation — the VTM simply performs fixed-ratio current multiplication. Operating the VTM without a PRM will deliver approximately 1.25 VDC at the output when 60 VDC is applied at the input, which can damage downstream 1V-core ASICs.
Minimize the primary-to-secondary loop area in PCB layout to reduce EMI and switching losses. The PC (Primary Control) pin should be pulled high to enable the VTM, and the TM (Temperature Monitor) pin provides an analog voltage proportional to internal junction temperature for thermal management. According to the Vicor datasheet, the TM pin output voltage scales with temperature and can be fed to an ADC for real-time thermal monitoring in safety-critical applications such as automotive or medical systems.
