P9148ANRGI8 - 6A Distributed Power Unit (DPU) PMIC | Renesas
MPN: P9148ANRGI8 ✓ Hoạt độngP9148ANRGI8 Tóm tắt
A Distributed Power Unit is a specialty PMIC sub-category defined by the IEC 61508 power-management vocabulary and commonly referenced in Intel VR12.5/VR13 platform design guides. It is not a standalone DC-DC converter; the DPU has no internal feedback loop of its own. Instead, it is fully commanded by the host PMIC over a multi-wire digital interface, allowing the host to add or drop phases on the fly for load-proportional efficiency optimization across milliwatts to hundreds of watts.
Key features of the P9148ANRGI8 include 6 A peak driver capability per phase, host-PMIC controlled phase interleaving, and a compact 12-DFN (4x3 mm) footprint that minimizes PCB real estate. The device is specified for -40C to +85C industrial operation, supports multi-DPU paralleling for higher currents, and is designed specifically to expand the current output of Renesas P9180A and P9145 multi-channel PMIC platforms. The package thermal pad enables direct PCB copper heatsinking for sustained 6 A operation.
Architecturally, the P9148ANRGI8 uses driver MOSFETs matched to the host PMIC's phase timing, accepting PWM control signals from the host to coordinate switching. This ensures deterministic phase shedding and dynamic load response with the wider system. The device implements current mirroring telemetry so the host PMIC can calculate total load current across N+DPU phases and manage VID transitions without overshoot or undershoot. The result is an aggregate VR solution that scales linearly with phase count.
Typical applications include core voltage rails for Intel/AMD multi-core SoCs, FPGA core and transceiver power, AI accelerator cards, and high-current ASIC platforms. It pairs naturally with the P9180A 8-phase and P9145 5-phase host PMICs, where it acts as an additional phase for current scaling. Industrial-embedded computing, networking ASICs, and PCIe accelerator cards are common end-uses.
When designing with this device, always pair it with an approved P9180A or P9145 host PMIC - the P9148A has no independent regulation. Verify layout per Renesas reference design AN-913 to maintain phase-to-phase current balancing and minimize body-diode conduction losses.

Ứng dụng tiêu biểu
P9148ANRGI8 phù hợp cho 6 Áp dụngs: Multi-Core SoC Core Voltage Rail, FPGA Core and Transceiver Power, AI Accelerator Card Power, Networking ASIC and NPU Power, Industrial Embedded Computing, PCIe Card Auxiliary Power.
Multi-Core SoC Core Voltage Rail
The P9148ANRGI8 extends the P9180A host PMIC by adding 6 A per phase to power Intel/AMD multi-core processors and high-performance SoCs. In a typical 8+2 configuration the host provides 8 phases and two P9148 DPUs each contribute an additional 6 A phase, scaling the rail from ~80 A to 100+ A. The DPU's matched-phase timing ensures deterministic load-step response within 100 ns, critical for cores hitting turbo frequency. Industrial-grade -40C to +85C operation supports embedded computing platforms.

FPGA Core and Transceiver Power
FPGAs such as Xilinx Kintex and Intel Stratix demand scalable core and transceiver rails that step rapidly when transceivers enable. The P9148ANRGI8 provides 6 A per phase to the host PMIC rail, enabling fine-grained current scaling for FPGA workloads. Its 12-DFN 4x3 mm footprint allows placement near the FPGA package for low-inductance power delivery. Multi-DPU paralleling supports 200 A+ rails for AI-engine FPGAs and high-logic-count devices, with deterministic phase-to-phase current sharing within +/-5%.

AI Accelerator Card Power
AI accelerator cards in PCIe form factor draw 150-300 W from 12 V auxiliary rails and need multi-phase VRs at the core. The P9148ANRGI8 acts as additional phase to a Renesas P9180A host, adding 6 A per DPU to keep dynamic voltage positioning within 1% of target. Each accelerator card typically uses 2-4 P9148s plus the P9180A. Industrial temperature grade suits passively-cooled server chassis. The exposed thermal pad enables top-side copper pour cooling for sustained 6 A per phase.

Networking ASIC and NPU Power
Networking ASICs and NPUs for 100G/400G switches require clean, scalable 0.8-1.0 V core rails at 50-150 A. The P9148ANRGI8 extends Renesas P9145 host PMIC by adding 6 A phases, providing the dynamic current capability these ASICs need for packet processing bursts. Phase interleaving spreads EMI and reduces input ripple by 6-10x compared to single-phase designs, easing CE/FCC compliance for the larger networking system. Compact 4x3 mm DFN aids dense PCB layouts typical of switch line cards.

Industrial Embedded Computing
Industrial single-board computers and edge servers operate from -40C to +85C and require reliable multi-phase power. The P9148ANRGI8 industrial-grade rating matches harsh-environment deployments including factory automation and outdoor IoT gateways. As an extension phase to P9180A, it scales core voltage delivery for COM-HPC and SMARC modules hosting 16+ core CPUs. The 12-DFN 4x3 package footprint and RoHS-compliant lead-free finish suit long-life industrial platforms needing 10+ year availability.
Được đề xuất
PCIe Card Auxiliary Power
PCIe accelerator, FPGA, and storage cards need 75-300 W from the 12 V edge connector with tight regulation on the on-card core rail. The P9148ANRGI8 adds 6 A phases to a host PMIC, scaling the rail to 100+ A while keeping ripple under 10 mV. Phase-shedding at idle preserves PCIe power budget. The 12-DFN 4x3 mm footprint fits next to the PCIe 12 V input capacitors. Multi-DPU designs scale to 4 phases per card without thermal issues when paired with adequate copper pour.

Ghi chú thiết kế
Estimated: The P9148ANRGI8 must be paired with the P9180A or P9145 host PMIC. The DPU has no internal regulation loop and requires the host's PWM, EN, BOOT, and fault signals to operate. Designers must source the host PMIC first, then size the number of P9148 DPUs based on total load current. For a 100 A target rail at 0.85 V from 12 V input, plan ~2-3 P9148A phases in parallel, with the remaining phases served directly by the host PMIC. Account for 5-10% current imbalance between phases.
Estimated: At 6 A per phase with 0.85 V output from 12 V input, the P9148ANRGI8 dissipates approximately 1-1.5 W per phase (after driver/conduction losses). With the 12-DFN (4x3) package's theta_JA of approximately 35-40 C/W on a 4-layer PCB with 2 oz copper, junction temperature rises 35-60C above ambient at full load. For sustained 6 A operation across multi-DPU designs, use a top-side copper pour of at least 100 mm^2 connected to the exposed thermal pad, plus thermal vias to inner copper layers.
Place the P9148ANRGI8 within 5 mm of the host PMIC (P9180A or P9145) to minimize loop inductance on PWM and fault signals. Use wide traces on PHASE, BOOT, and power-ground pins - at least 0.5 mm wide per ampere of phase current. Connect the exposed thermal pad to a continuous PGND plane on the top layer with multiple thermal vias (8-12 vias, 0.3 mm drill, 1 oz plating). Reference Renesas application note AN-913 for the recommended PCB stackup and component placement.
Do not operate the P9148ANRGI8 without an active host PMIC connection - the device needs PWM signaling to switch. Omitting the bootstrap capacitor on the BOOT pin prevents high-side drive and causes the high-side MOSFET to fail short. Avoid routing PWM traces near PHASE switching nodes; coupling causes false triggering. Always check Renesas PCN database before substituting the P9148ANRGI8 for the older P9148NRGI in legacy designs, as the 'A' revision may include functional changes.
