A non-isolated Point-of-Load (PoL) DC-DC converter module is a packaged switching power stage placed adjacent to a load ASIC or processor to convert a higher intermediate bus voltage into a tightly-regulated lower rail with high efficiency and minimal PCB footprint. PoL modules differ from isolated converters in that they share a common ground reference between input and output, eliminating the bulky transformer isolation barrier. Within the broader power hierarchy, this places them between upstream Intermediate Bus Converters (IBCs) and the final LDO/pol regulation stage on a processor or SoC's core, memory, or I/O rails, where fast transient response and current-density per square centimeter matter most.
Key feature highlights include a wide 40 V to 60 V input range aligned with 48 V nominal telecom and datacom buses, a trimmable output range of 10.0 V to 12.5 V, up to 1000 W continuous / 1100 W transient operation, and a >1 MHz switching frequency that allows output filtering with small ceramic capacitors. PMBus®-compatible digital telemetry provides real-time monitoring of input voltage, output voltage, output current, and temperature, while SM-ChiP packaging enables flexible thermal management with low top- and bottom-side thermal impedance.
Architecturally, the converter combines a ZVS buck-boost stage to step down the 48 V bus with a Sine Amplitude Converter that produces a low-noise, high-bandwidth regulated output. This two-stage approach avoids the duty-cycle limitations of single-stage buck converters at high step-down ratios and enables the >1 MHz switching frequency without sacrificing efficiency.
Typical applications include 48 V-to-12 V point-of-load conversion in datacom servers and AI accelerator cards, telecom equipment power distribution, industrial 48 V bus regulation, high-performance computing and FPGA power rails, and battery-backed 48 V systems where high efficiency and density are required. When designing with this device, mount it on a thermally adequate PCB footprint and observe the SM-ChiP handling instructions to maximize top- and bottom-side heat extraction.

典型應用
DCM3717S60D13K0TN1-VICOR 適用於 6 應用s: 48V-to-12V Point-of-Load in Datacom Servers, AI Accelerator Card Power Rails, Telecom 48V Bus Power Distribution, High-Performance Computing (HPC) and FPGA Power, Industrial 48V Bus Regulation, Battery-Backed 48V Systems.
48V-to-12V Point-of-Load in Datacom Servers
The DCM3717S60D13K0TN1's 96.5% peak efficiency and 82 A continuous output at 12.2 V make it well-suited for 48 V bus to 12 V rail conversion in hyperscale datacom servers. Its >1 MHz switching frequency enables small-ceramic output capacitance, freeing board area for high-speed SERDES and memory channels. SM-ChiP packaging with low top- and bottom-side thermal impedance allows top-side or bottom-side cooling in dense 1U/2U chassis, while PMBus telemetry enables real-time power monitoring per server for hyperscaler fleet management.

AI Accelerator Card Power Rails
AI accelerator cards (GPUs, TPUs, custom ASICs) often require hundreds of watts at low voltages with tight transients. The DCM3717S60D13K0TN1's 1000 W continuous / 1100 W transient peak capability and >1 MHz control bandwidth deliver fast transient response to GPU load steps, while the 96.5% peak efficiency minimizes thermal load on densely-packed accelerator boards. Mounted adjacent to the accelerator ASIC on the same PCB, it converts the 48 V rack bus to a clean 12 V intermediate rail that downstream VRs step down to the core voltage.
推薦
Telecom 48V Bus Power Distribution
Telecom equipment operates from a nominally 48 V DC bus with -36 V to -72 V excursions. The DCM3717S60D13K0TN1's specified 40 V to 60 V input range is aligned with the central portion of the telecom bus envelope, producing a regulated 12.2 V rail for baseband processors, DSPs, and RF power amplifier circuits. Non-isolated PoL topology is acceptable because the upstream rectifier in the central office provides the galvanic isolation barrier, and the high efficiency reduces HVAC load in densely-populated telecom racks.
推薦
High-Performance Computing (HPC) and FPGA Power
FPGA-based HPC boards and high-end test instruments require stable mid-voltage rails (10-12 V) feeding point-of-load VRMs for core, memory, and transceiver supplies. The DCM3717S60D13K0TN1's trimmable 10.0 V to 12.5 V output range accommodates direct powering of FPGA auxiliary rails with no intermediate regulation stage. PMBus telemetry gives the FPGA host processor visibility into rail health for predictive maintenance, and the surface-mount SM-ChiP package simplifies assembly on densely-routed HPC PCBs.
推薦
Industrial 48V Bus Regulation
Industrial machinery and process-control systems increasingly adopt 48 V distribution for motor drives, actuators, and sensor networks to reduce I²R losses over long cable runs. The DCM3717S60D13K0TN1 brings the 48 V bus down to a regulated 12.2 V point-of-load for PLCs, HMIs, and industrial PCs. The wide 40 V to 60 V input tolerance accommodates voltage droop on long industrial cables, while the >1 MHz switching frequency keeps output filters small enough to fit in space-constrained DIN-rail enclosures.
推薦
Battery-Backed 48V Systems
Battery-backed 48 V systems in data centers, telecom central offices, and mobile military platforms need DC-DC conversion that maintains output regulation as the battery discharges from 54 V to 42 V. The DCM3717S60D13K0TN1's 40 V to 60 V input range covers the full discharge envelope of a 48 V nominal lithium-ion or lead-acid battery string, producing a stable 12.2 V output for downstream loads. The non-isolated PoL topology is appropriate when the battery string is already referenced to chassis ground, and PMBus telemetry reports SoH-relevant data such as input voltage and current.

主要差異化特點
- 1000 W continuous / 1100 W transient in SM-ChiP (對比DCM3717S60E13G5TN1)
- 96.5% peak efficiency at 1 kW (對比DCM3717S60E13G5TN1)
- PMBus telemetry with >1 MHz control bandwidth (對比DCM3735S60D13K0TN1)
設計說明
The SM-ChiP package offers low top- and bottom-side thermal impedance, but at 1000 W continuous with 96.5% peak efficiency the converter still dissipates up to ~36 W at full load. Provide a PCB footprint with adequate top-side copper pour (or attach a heatsink to the top of the SM-ChiP) and consider bottom-side PCB cooling as recommended in the Vicor SM-ChiP thermal management guideline. Derate output power if ambient temperature exceeds the datasheet-specified operating range.
Place the DCM3717S60D13K0TN1 as close as practical to the load ASIC to minimize PCB parasitic inductance and resistance in the 12 V output path. Use wide copper pours/arrays of vias on both input and output power pins to handle 82 A continuous current without excessive voltage drop. Follow the Vicor SM-ChiP land pattern reference exactly; deviations can cause thermal interface resistance increases or solder-joint fatigue under thermal cycling.
PMBus telemetry signals (clock, data, alert) are sensitive to noise from the high-current switching stage. Route PMBus traces away from switching node copper pours, use a ground reference plane under the PMBus traces, and place the PMBus pull-up resistors close to the DCM module. Decouple the PMBus supply pin per Vicor datasheet recommendations. Avoid running PMBus traces parallel to input/output power planes to prevent coupled noise from corrupting telemetry readings.
Estimated: at 82 A continuous output with a typical 12.2 V rail, even 1 milliohm of PCB-trace resistance drops ~82 mV - enough to push downstream VRMs out of regulation. Verify that input voltage stays above the undervoltage-lockout threshold under all load transients, especially during inrush. Do not bypass the upstream inrush limiting, and follow the Vicor SM-ChiP handling instructions during PCB assembly to avoid damaging the package thermal interface.
