XDPE19283B0000XUMA1 Présentation
A multiphase buck controller is a power-management IC that drives multiple synchronous buck phases in parallel to supply high-current CPU/GPU/SoC core rails. Within the broader power-management IC hierarchy, a digital multiphase controller sits above simple voltage regulators and below fully integrated PMICs; it pairs an analog front end with a programmable digital core (in this case, an ARM Cortex-M0) for telemetry, fault handling, and adaptive loop compensation.
Key features include a programmable ARM Cortex-M0 processor for non-volatile configuration, PMBus rev 1.3 compliant serial interface supporting up to 1 MHz bus speed, and per-phase current sensing for accurate load-line regulation. The controller integrates high-performance analog front ends with digital control loops, supports flexible PWM phase order and phase shedding, and provides extensive telemetry for voltage, current, and temperature.
The XDPE19283B employs an analog front-end plus digital control-loop architecture, where the ARM Cortex-M0 manages telemetry, fault response, and adaptive voltage positioning. Compared with purely analog multiphase controllers, the digital core enables firmware-updatable configurations, per-rail loop tuning, and full PMBus monitoring - critical for AMD SVI3 platforms that require precise dynamic VID transitions.
Typical applications include AMD AM5/TR5 desktop and server CPU VR cores, workstation motherboard Vcore rails, GPU accelerator cards with SVI3 interfaces, and high-end desktop VRM modules. The 8-phase capability delivers the high continuous currents demanded by modern multi-core CPUs under transient load.
When designing with this part, follow the Infineon reference layout for the PG-VQFN-40-13 exposed-pad package and observe AMD SVI3 platform bring-up sequencing. The PMBus address and rail configuration are set by external strapping resistors.

Applications typiques
XDPE19283B0000XUMA1 convient pour 6 applications: AMD AM5 Desktop CPU Vcore Rail, AMD TR5 Server Workstation Vcore, High-End Desktop Workstation Motherboard, GPU Accelerator Card Vcore, VRM Module for Server CPU, High-Performance Computing Server Platform.
AMD AM5 Desktop CPU Vcore Rail
The XDPE19283B0000XUMA1 is qualified for AMD SVI3 Rev 2.0 platforms and is a natural fit for AMD AM5 desktop CPU Vcore regulation, with 8 phases in 8+0 or 6+2 configurations. Its 0.25 V to 2.8 V output range covers low-power idle states through high-current turbo boost transients, while the 5 mV VID step matches AMD SVI3 dynamic voltage positioning. The PMBus rev 1.3 interface at 1 MHz enables fast telemetry polling by BIOS for adaptive voltage management.

AMD TR5 Server Workstation Vcore
Server-grade AMD TR5 platforms benefit from the XDPE19283B0000XUMA1's dual-loop topology, which can drive two rails (Vcore and SoC) from a single controller in a 4+4 configuration. Each loop can be independently compensated and monitored over PMBus, allowing per-rail telemetry and fault isolation. The ARM Cortex-M0 non-volatile configuration supports secure boot and per-platform calibration data retention.

High-End Desktop Workstation Motherboard
Workstation motherboards with multi-CPU or workstation-GPU configurations can leverage the XDPE19283B0000XUMA1's dual-loop capability to drive a CPU Vcore and a discrete GPU core rail from one controller. The 7+1 configuration allocates 7 phases to CPU Vcore for high continuous current while dedicating 1 phase to a secondary GPU or auxiliary rail, sharing PMBus telemetry across both.

Principaux différenciateurs
- Dual-loop topology in a single 40-pin VQFN (vs XDPE12284C0000XUMA1)
- AMD SVI3 Rev 2.0 native compliance (vs Generic digital multiphase controllers)
- PMBus rev 1.3 at 1 MHz bus speed (vs Standard 400 kHz PMBus)
Notes de conception
The PG-VQFN-40-13 exposed pad is the primary thermal path for the XDPE19283B0000XUMA1. Under 8-phase switching operation the controller itself dissipates moderate power, but combined with the adjacent DrMOS stages the local copper area must reach at least 1 square inch of unbroken pour, with 6-8 thermal vias under the pad to inner power planes. Insufficient thermal relief causes the controller's internal temperature sense (TSEN) to throttle or assert FAULT prematurely.
Follow the Infineon reference layout for the XDPE19283B0000XUMA1: place PMBus pull-ups (typically 10 kohm to 3.3 V) close to the controller, route SDA/SCL away from PWM switching nodes, and use Kelvin sensing for VSEN and CS lines directly to the output capacitors and inductor DCR sense points. The SVI3 serial interface traces to the AMD CPU socket should be length-matched and reference-grounded to avoid VID decoding errors.
Strapping resistors on ADDR, CONFIG, and any platform-specific pins set the PMBus address and SVI3 behavior at power-up. Place these resistors as close as possible to the controller pins to prevent noise coupling. Use guard traces around CS sense lines to reject switching noise from adjacent PWM outputs, and ensure the exposed pad has a single solderable opening with via stitching on a 0.5-1.0 mm pitch.
Estimated: the XDPE19283B0000XUMA1's PMBus address is set by external strapping; ensure the ADDR resistor matches the platform's SMBus topology to avoid conflicts with other PMBus devices on the same bus. Do not connect NC pins to any net - some are reserved for factory test modes and can cause unexpected behavior. Always validate the SVI3 firmware sequence against AMD's reference code before mass production.
