Product details
Overview
TPS53627RSMR from Texas Instruments is a 2-phase, VR13 SVID-compliant synchronous buck controller for CPU VCORE and DDR memory power delivery. It supports 1–2-phase operation, 4.5–28-V input, 0.5–2.3-V output, 300-kHz to 1-MHz switching frequency, and driverless high-frequency operation with D-CAP+™ control architecture.
For engineers reviewing the TPS53627RSMR datasheet, TPS53627RSMR pinout, TPS53627RSMR application, or TPS53627RSMR equivalent, key selection considerations include SVID interface compatibility, phase balancing (AutoBalance™), OSR/USR transient response tuning, VOUT slew rate programmability up to 20 mV/µs, and support for discrete, Power Stage™, or DrMOS implementations.
Technical Context
The TPS53627RSMR implements D-CAP+™ control with overlapping pulse support to minimize output capacitance while delivering fast load-transient response. Its SVID interface enables dynamic voltage scaling and telemetry reporting (VR_READY, ALERT, VR_HOT) for Intel VR13-compliant microprocessors.
It integrates programmable ON-pulse extension for transient boost, selectable 8-level current limit, auto DCM/CCM mode switching, and adjustable voltage positioning. Phase balancing is handled via AutoBalance™ without external current-sense resistors, relying on internal CSP/CSN feedback paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VOUT Slew Rate | Up to 20 mV/µs - Adjustable via SVID command for controlled ramp-up/down during VID transitions. |
| Operating Temperature | –40°C to +105°C - Qualified for extended-temperature industrial and server motherboard environments. |
Pinout & Package
The TPS53627RSMR uses a thermally enhanced 4 mm × 4 mm, 32-pin VQFN (RSM) package with exposed thermal pad. Pin 1 is located in Quadrant Q2 per tape-and-reel orientation; soldering the thermal pad is mandatory for thermal and mechanical reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PWM1 / PWM2 | Phase gate drive outputs | Driverless outputs directly interface with external high-side MOSFET gates in each phase. |
| CSP1 / CSN1 / CSP2 / CSN2 | Current-sense inputs | Differential inputs for phase current monitoring; enable AutoBalance™ and overcurrent protection without sense resistors. |
| CSD9537x | Power stage interface | Reference designates compatibility with TI CSD9537x integrated power stages (e.g., CSD95372B) for optimized layout and performance. |
| SVID bus pins (ADDR, CLK, DATA) | Serial VID interface | Supports VR13-compliant bidirectional communication for VID programming, telemetry, and fault reporting. |
| SKIP | Mode selection | Pin-strappable input to enable/disable SKIP mode for light-load efficiency optimization in DCM. |
Key Features
| Feature | Design Value |
|---|---|
| D-CAP+™ control architecture | Enables zero-external-compensation design with fast transient response and minimal output capacitance. |
| AutoBalance™ phase balancing | Eliminates need for external current-sense resistors and ensures equal current sharing between phases without calibration. |
| Programmable ON-pulse extension | Boosts high-side conduction during load transients to maintain regulation under sudden current steps. |
| 8-level OSR/USR configuration | Allows fine-grained tuning of transient recovery behavior to match system-specific capacitor ESR and layout parasitics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar VR13 buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS53632GRTAR | Integrated 30-A DrMOS driver + controller in 5-mm × 6-mm QFN; no external power stage needed. | Targeted at space-constrained client platforms; lacks full SVID telemetry (no VR_HOT) and OSR/USR granularity. | Choose when board area is critical and ≤30-A output suffices; avoid for server-grade telemetry or >40-A designs. |
| ISL95815IRZ | VR13-compliant 2-phase controller with similar SVID interface but uses traditional voltage-mode control and external current sensing. | Requires external current-sense resistors and compensation components; lower integration than TPS53627RSMR. | Choose only if legacy design reuse or vendor consolidation with Renesas power portfolio is required. |
Compared with TPS53627RSMR, TPS53632GRTAR trades external power stage flexibility for compactness and ease of layout, while ISL95815IRZ requires more BOM components and offers less transient agility-making TPS53627RSMR optimal for high-performance, thermally demanding VR13 systems needing full SVID feature set and minimal output capacitance.

FAQ
What is the maximum supported output current for TPS53627RSMR?
The TPS53627RSMR itself does not define a fixed maximum output current-it is a controller that scales with external power stage selection. When paired with TI CSD95372B Power Stages (rated 60 A per phase), the TPS53627RSMR supports up to 120 A in 2-phase configuration. Actual current capability depends on thermal design, PCB layout, and chosen FETs or power blocks.
Does TPS53627RSMR require external compensation components?
No, the TPS53627RSMR uses D-CAP+™ control architecture and operates without external compensation components. Its adaptive loop response is tuned internally via OSR/USR settings and VOUT slew rate programming, eliminating the need for external RC networks typically required in voltage-mode or current-mode controllers.
Can TPS53627RSMR operate in single-phase mode?
Yes, the TPS53627RSMR supports configurable 1-phase or 2-phase operation via pin strapping. In single-phase mode, it delivers full functionality-including SVID interface, OSR/USR, and AutoBalance™ (deactivated)-and maintains high efficiency across light-to-heavy loads using programmable DCM/CCM mode switching.
What is the purpose of the CSP/CSN pins on TPS53627RSMR?
The CSP1/CSN1 and CSP2/CSN2 pins on TPS53627RSMR are differential current-sense inputs used for phase current monitoring. They enable AutoBalance™ phase current matching, cycle-by-cycle overcurrent protection, and accurate current reporting to the SVID host-without requiring external sense resistors or amplifiers.
Is TPS53627RSMR compatible with non-Intel VR13 platforms?
The TPS53627RSMR is designed for Intel VR13 SVID compliance, but its core buck control features (D-CAP+™, programmable frequency, OSR/USR) remain functional in non-VR13 systems. However, SVID-specific signals (VR_READY, ALERT, VR_HOT) and VID command parsing are Intel-protocol-dependent; use requires SVID host controller or firmware adaptation.
