VTM2313S60Z01A4T00 Overview
A VTM Current Multiplier is a fixed-ratio DC-DC isolation and voltage transformation stage that performs the role of an isolation transformer-rectifier in a Factorized Power Architecture. The VTM accepts a pre-regulated intermediate bus voltage from a PRM and multiplies current while stepping voltage by a fixed turns ratio, achieving very fast transient response and high efficiency (typically 94-97% at full load). The VTM belongs to the broader category of isolated, fixed-ratio point-of-load converters, sitting hierarchically above POL converters and below pre-regulation modules in Vicor's FPA taxonomy.
Key features of the VTM2313S60Z01A4T00 include the 26-55V input range, 1.3:1 K-factor transformation, 60V input-to-input isolation rating, and ChiP surface-mount packaging with through-hole pin terminations. The 2313 designation indicates a 23mm x 13mm ChiP body. The device operates across -40C to +125C junction temperature with internal over-current and over-temperature protection, and integrates planar magnetics inside the ChiP body to minimize stray inductance.
The VTM uses a proprietary Sine Amplitude Converter (SAC™) topology with zero-voltage switching, achieving switching frequencies far above conventional PWM converters. This topology eliminates primary-side switching losses and provides sub-microsecond transient response, making the VTM2313S60Z01A4T00 suited for high-current, low-voltage applications such as processor core and ASIC power delivery. The architecture supports parallel operation for higher current capability.
Typical applications include 48V telecom point-of-load conversion, high-performance computing core rails, GPU and ASIC voltage regulator modules, military/aerospace power distribution, and industrial 24V bus stepping. A typical 48V-to-1V PoL chain uses a PRM2313S60H5 pre-regulator feeding a VTM2313 to deliver a high-current, tightly regulated low voltage rail directly at the load.
Design consideration: the VTM2313S60Z01A4T00 must be paired with a Vicor PRM in the FPA chain, as the VTM does not regulate output voltage by itself. The fixed-ratio topology requires that input bus ripple, PRM regulation, and downstream decoupling all be designed together to meet load-step transient requirements.

Typical Applications
VTM2313S60Z01A4T00 is suitable for 6 applications: 48V Telecom Point-of-Load Conversion, High-Performance Computing Core Rails, GPU and ASIC Voltage Regulator Modules, Industrial 24V Bus Step-Down, Military and Aerospace Power Distribution, Battery-Powered 48V Server Racks.
48V Telecom Point-of-Load Conversion
The VTM2313S60Z01A4T00 fits 48V telecom point-of-load conversion because its 1.3:1 fixed-ratio current multiplication delivers a low-impedance, high-current bus directly at the load with sub-microsecond transient response. Placed downstream of a PRM2313S60H5 pre-regulator on a 48V backplane, it converts the regulated intermediate bus to a low-voltage high-current rail for ASICs and FPGAs. The 60V input-to-input isolation rating covers telecom battery voltage transients including 100V surge events.
Recommended
High-Performance Computing Core Rails
The VTM2313S60Z01A4T00 suits high-performance computing core power delivery because the SAC topology's zero-voltage switching and integrated planar magnetics achieve 94-97% efficiency while delivering fast transient response for processor core loads. In HPC systems the VTM stages current directly at the load, eliminating distribution losses from a 48V bus to 1V core rails. The 23x13mm ChiP footprint enables dense VRM placement adjacent to high-current processors.
Recommended
GPU and ASIC Voltage Regulator Modules
The VTM2313S60Z01A4T00 fits GPU and ASIC VRM applications because its fixed-ratio current multiplication by 1.3:1, combined with the upstream PRM, delivers the high di/dt capability required by modern GPU and ASIC load steps. Placed directly under the GPU package area, the VTM ChiP's low-profile ChiP form factor minimizes vertical clearance while delivering the current density required. Parallel operation of multiple VTMs scales output current for multi-rail GPU designs.
Recommended
Industrial 24V Bus Step-Down
The VTM2313S60Z01A4T00 applies to industrial 24V bus step-down applications because its 60V isolation rating accommodates the transient over-voltages found on factory 24V buses, while the fixed-ratio transformation current output delivers tightly regulated, low-ripple power to industrial controllers. The wide -40C to +125C junction temperature range supports harsh factory-floor environments. A PRM+VTM pair replaces conventional multi-stage isolated DC-DC converters.
Recommended
Military and Aerospace Power Distribution
The VTM2313S60Z01A4T00 is used in military and aerospace power distribution because its ChiP packaging, wide temperature range, and robust isolation meet the environmental and EMI requirements of airborne and vehicle platforms. The SAC topology's zero-voltage switching minimizes EMI generation, simplifying system-level EMI compliance. Its small ChiP footprint supports SWaP-C-optimized avionics and vehicle electronics designs.
Recommended
Battery-Powered 48V Server Racks
The VTM2313S60Z01A4T00 applies to 48V battery-backed server rack power distribution because its high efficiency (>94%) preserves battery runtime while delivering high-current low-voltage rails to server processors. The ChiP's planar magnetics eliminate bulky inductors, allowing dense power-stage placement under server boards. In a battery-backed 48V architecture, the VTM's 60V isolation covers battery float-charge voltage and transient excursions.

Design Notes
The VTM2313S60Z01A4T00 must be paired with a Vicor PRM2313S60-family pre-regulator upstream; the VTM does not regulate output voltage on its own and will pass input transients to the load if the PRM is omitted. According to Vicor's Factorized Power Architecture documentation, design the PRM+VTM chain together, including PRM regulation bandwidth and VTM decoupling, to meet load-step transient requirements. Estimated: For a typical 48V-to-1V design using PRM2313S60H5 (26-55V input, 1.3-1.8x trim ratio) followed by VTM2313 1.3:1, the VTM delivers approximately 36-42V intermediate bus and 28-32V output, which is too high for direct 1V - add a downstream buck regulator.
The ChiP 23x13mm package has limited thermal headroom at full output current. Provide a continuous copper pour on both top and bottom PCB layers beneath the ChiP body, with thermal vias to inner copper planes. Estimated: at 94-97% efficiency and full rated output, internal power dissipation is 3-6% of output power; for a 200W load this means 6-12W of heat that must be conducted through the ChiP body to the PCB. Without adequate copper area, junction temperature will exceed the +125C rating.
The through-hole Tm (long-pin) terminations require plated through-holes sized for the ChiP pin geometry - consult Vicor's VTM2313 datasheet land pattern specification. Place input and output ceramic capacitors as close as possible to the ChiP VIN/VOUT pins to minimize parasitic inductance; use a combination of 1uF X7R high-frequency and 10-22uF bulk ceramics per the VTM2313 reference layout. Keep the control pin traces short and away from switching nodes.
Do not connect a VTM to a non-regulated DC source - the VTM will pass unregulated transients to the load. Verify that the upstream PRM is sized to deliver the VTM's required input current at the worst-case load step. Do not parallel VTMs without consulting Vicor's paralleling application note - unequal current sharing can cause thermal runaway in one of the modules.
