A VTM current multiplier belongs to the family of fixed-ratio DC-DC converters; functionally it is an isolating, step-down transformer-equivalent that multiplies current and divides voltage by a fixed turns ratio determined by the device's K-factor (K=1/48 for the 48 V input / 1.25 V output parts in this family). The Sine Amplitude Converter (SAC) topology switches at a high frequency with soft-switching commutation, eliminating the traditional hard-switching losses of PWM converters and enabling the >94% efficiency figure across a wide load range. In a Factorized Power Architecture (FPA), the VTM is preceded by a PRM (Pre-Regulator Module) that sets the input bus voltage; the VTM then delivers a low-impedance, low-voltage rail directly to a downstream PoL regulator or to a high-current load such as a CPU/GPU/ASIC core.
Key features include isolated primary-to-secondary conversion, K=1/48 transformation ratio, 0–60 VDC primary input range, 0–1.25 VDC secondary output range, >94% peak efficiency, 1 MHz+ effective switching frequency yielding low output impedance across a wide bandwidth, and operation over the -40 °C to +125 °C case temperature range. The 1323 ChiP (33.02 x 22.86 x 7.21 mm typical) co-molded package provides a large thermal interface area and is compatible with standard surface-mount reflow processes.
Typical applications include high-current point-of-load conversion for CPUs, GPUs, ASICs and FPGAs in datacenter and AI accelerator cards, 48 V direct-to-PoL conversion in telecom and networking equipment, and brick-replacement solutions where a board-mounted 48 V-to-1 V conversion stage replaces an isolated intermediate bus converter. Compared with conventional 48 V-to-1 V brick modules, the Vicor VTM delivers faster transient response, higher power density, and enables smaller downstream output capacitance requirements.
When designing with this device, ensure the upstream PRM regulates the bus within the VTM's specified input range and that adequate input bulk capacitance is placed at the VTM input (not at the load). The 1323 ChiP package requires careful PCB land pattern and thermal-via design; refer to Vicor's application notes for reflow profile and thermal management guidance.

典型應用
VTM48MP010C105AG0 適用於 6 應用s: 48V-to-PoL Conversion for AI Accelerator Cards, Telecom and Networking 48V-to-1V Power Rails, High-Performance Server and Storage VR Cores, Industrial 48V Bus Distributed Power, Aerospace and Defense 48V Avionics Buses, LED Driver and High-Current Lighting Power.
48V-to-PoL Conversion for AI Accelerator Cards
The VTM48MP010C105AG0's K=1/48 fixed ratio and >94% SAC efficiency make it a strong fit for stepping a 48 V datacenter bus down to a sub-1.2 V core rail on AI accelerator (GPU/ASIC) cards. Placed downstream of a Vicor PRM (or any 36–60 VDC regulated source), it delivers low-impedance, high-current power directly to the load while allowing bulk capacitance to be relocated to the VTM input — a key advantage on dense accelerator PCBs where output-side bulk cap area is constrained. Per the VTM48M datasheet, its low AC impedance beyond typical downstream regulator bandwidth lets engineers reduce output-cap count and shrink the PoL footprint.

Telecom and Networking 48V-to-1V Power Rails
In telecom and networking hardware, the VTM48MP010C105AG0 enables a compact, isolated 48 V-to-1 V conversion stage that replaces conventional intermediate-bus bricks. Its 0–60 VDC primary input covers the standard -48 V telecom bus operating window with margin, and the >94% SAC efficiency reduces converter-stage losses compared with legacy 48 V brick modules. The 1323 ChiP surface-mount package supports automated pick-and-place assembly on telecom-grade PCBs, while the -40 °C to +125 °C case-temperature rating suits outdoor and uncontrolled-airflow cabinet deployments.
推薦
High-Performance Server and Storage VR Cores
Server CPU and high-end storage-controller core rails demand high-current, low-voltage, fast-transient power — exactly the operating envelope of the VTM48MP010C105AG0. Its K=1/48 ratio and SAC topology deliver a near-ideal voltage source to the downstream PoL or directly to the load, and its effective switching frequency above 1 MHz yields low output impedance across a wide bandwidth. The trade-off is that the VTM itself is a current multiplier, not a regulator — designers must include upstream regulation (a Vicor PRM is the canonical pair) and downstream filtering to meet core-rail tolerance and transient specs.
推薦
Industrial 48V Bus Distributed Power
In industrial 48 V distributed-power systems (factory automation, robotics, battery-powered mobility), the VTM48MP010C105AG0 provides an isolated, high-efficiency step-down to 1 V-class rails for embedded processors, FPGAs and motor-control ASICs. The 1323 ChiP's co-molded thermal interface supports sustained high-current operation with appropriate PCB thermal-via design, and the wide -40 °C to +125 °C case-temperature range covers typical industrial enclosures. Note that industrial 48 V buses often have wider input transients — designers should verify upstream PRM hold-up or add input bulk capacitance at the VTM input to ride through bus transients.

Aerospace and Defense 48V Avionics Buses
Aerospace and defense platforms increasingly adopt 48 V power distribution to reduce wiring weight, and the VTM48MP010C105AG0 with its >94% SAC efficiency and 1323 ChiP rugged co-molded package is a candidate for isolated 48 V-to-1 V conversion in avionics subsystems. Its wide -40 °C to +125 °C case-temperature rating covers most avionics thermal environments, and its transformer-based isolation supports primary-to-secondary isolation per the VTM48M datasheet. Aerospace designers should confirm that specific lot-level traceability, MIL-STD-704/MIL-STD-1275 compliance, and shock/vibration qualifications match program requirements before selection.
推薦
LED Driver and High-Current Lighting Power
Although not a primary LED-driver topology, the VTM48MP010C105AG0's high-current, low-voltage, isolated-output capability suits high-brightness LED arrays and laser-diode drivers that need a stable 1 V-class source at high current from a 48 V bus. Designers can pair it with a downstream constant-current regulator to set the LED current. The SAC topology's low output impedance beyond typical downstream regulator bandwidth is useful for pulse-width-modulated LED current profiles, where fast transient response preserves optical output fidelity.

設計說明
The VTM is a current multiplier, not a regulator — VOUT = VIN × K where K=1/48. Per the VTM48M datasheet, if your design needs regulated output tolerance or dynamic trim, you MUST add upstream regulation (typically a Vicor PRM regulating the 48 V bus to a fixed value) and/or a downstream PoL regulator. Using a VTM alone with an unregulated bus will pass bus transients directly to the load and may damage downstream silicon.
The 1323 ChiP co-molded package provides a large thermal interface area and is rated for -40 °C to +125 °C case temperature. However, full-load dissipation is non-trivial: estimated 6–8 W internal loss at peak load on a >94% efficient device. Per the VTM48M datasheet, the recommended PCB land pattern uses an array of thermal vias under the ChiP thermal pad to spread heat into inner copper planes; omitting the via array is a common cause of thermal shutdown and derating in ChiP-module designs.
Place bulk input capacitance at the VTM primary-side input, NOT at the load. The SAC topology presents low AC impedance beyond the bandwidth of most downstream regulators, so capacitance normally at the load can be relocated to the VTM input per the VTM48M datasheet. This reduces output-side cap count and saves board area but requires adequate input bulk to handle the reflected load transients at the VTM primary.
Follow Vicor's reference PCB land pattern exactly for the 1323 ChiP — the land pattern and pin/pad geometry are part of the design's thermal and electrical performance, not just mechanical attachment. Per the VTM48M datasheet, the ChiP package's pick-and-place compatibility assumes the standard reflow profile; non-standard profiles or hand-solder rework can damage the co-molded package and void warranty.
