Product details
Overview
TPS51610IRHBR from Texas Instruments is a dual-phase, synchronous buck controller IC designed exclusively for IMVP-6/6.5-compliant mobile CPU core power delivery. It supports 0.5–1.5 V output with ±0.5% regulation accuracy, 600 kHz switching frequency, and integrated gate drivers for high-side and low-side MOSFETs. It is deployed in ultrabook and thin-and-light notebook VRMs.
For engineers reviewing the TPS51610IRHBR datasheet, TPS51610IRHBR pinout, TPS51610IRHBR application, or TPS51610IRHBR equivalent, key selection criteria include IMVP-6.5 compliance, dual-phase current balancing, adaptive on-time control, and Intel CNDA-required access to full specification documents.
Technical Context
The TPS51610IRHBR implements an adaptive on-time (AOT) PWM control architecture with differential remote sensing, enabling fast transient response and tight DC regulation under dynamic load conditions typical of Intel mobile processors. It integrates phase-interleaved timing, DCR current sensing, and thermal compensation for accurate per-phase current reporting.
It requires external PMOS/NMOS driver stages and supports programmable overcurrent protection via RDS(on)-based or resistor-based sensing. The device operates across –10°C to 105°C ambient and communicates with the processor via SVID interface for dynamic voltage identification and telemetry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-phase IMVP-6.5 controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS51621RHAR | 40-pin VQFN, supports 3-phase operation and higher current (up to 60 A), includes integrated MOSFET drivers with higher peak current (2 A) | Targeted at higher-TDP mobile CPUs (e.g., Core i9-H series) and platforms requiring three-phase interleaving | Select TPS51621RHAR only if platform exceeds 40 A requirement or mandates 3-phase topology |
| RT8803AZSP | 32-pin QFN, IMVP-6.5 compliant but uses fixed-frequency PWM (not AOT); lacks thermal compensation for DCR sensing | Used in cost-sensitive mainstream notebooks where transient response margin is relaxed | Choose RT8803AZSP only when SVID compatibility is required but adaptive control and precision thermal compensation are not critical |
Compared with TPS51610IRHBR, TPS51621RHAR offers higher phase count and current capability at the cost of larger footprint and increased BOM complexity, while RT8803AZSP provides basic IMVP-6.5 functionality without adaptive on-time or thermal-aware current sensing-making TPS51610IRHBR optimal for balanced performance, size, and precision in mainstream ultrabooks.

FAQ
Is TPS51610IRHBR compatible with Intel IMVP-7 or later specifications?
No, TPS51610IRHBR is certified only for IMVP-6 and IMVP-6.5 compliance. It does not support IMVP-7 features such as SVID v3.0, enhanced telemetry, or new PROCHOT# signaling protocols. For IMVP-7 platforms, TI recommends TPS51650 or newer controllers explicitly qualified for that revision.
Does TPS51610IRHBR require an Intel CNDA to obtain full documentation?
Yes, TPS51610IRHBR is subject to Intel's Confidentiality and Non-Disclosure Agreement (CNDA). Full datasheets, design guides, and SVID interface details are restricted and accessible only to end users with an active CNDA on file with Intel. Contact [email protected] for eligibility verification before requesting documentation.
What is the recommended external MOSFET pairing for TPS51610IRHBR?
TI recommends CSD18532KCS (high-side) and CSD18533KCS (low-side) 30 V NexFET™ power MOSFETs for optimal efficiency and thermal performance. These devices match the TPS51610IRHBR's 1 A gate drive capability and support ≤25 ns dead-time control for minimized shoot-through risk.
Can TPS51610IRHBR operate in single-phase mode?
No, TPS51610IRHBR is a dual-phase-only controller and does not support single-phase configuration. Both PHASE1 and PHASE2 outputs must be used with matched external power stages; disabling one phase violates IMVP-6.5 compliance and disables SVID communication.
What thermal pad soldering guidelines apply to TPS51610IRHBR's QFN package?
TPS51610IRHBR's RHB package requires a 3×3 mm thermal pad with ≥80% solder coverage and 6–8 vias (0.3 mm diameter, spaced ≤1 mm apart) connecting to inner ground planes. TI recommends Type 3 solder paste and reflow profile peaking at 260°C for 10 seconds to ensure void-free thermal interface.
