Product details
Overview
TPS51610RHBT from Texas Instruments is a dual-phase, high-efficiency synchronous buck controller designed exclusively for Intel IMVP-7/8 mobile CPU core power delivery. It supports 0.25–1.5 V output with ±0.5% DC accuracy, 1.5 MHz switching frequency, and integrated gate drivers for external MOSFETs. It operates in D-CAP2™ mode with adaptive voltage positioning (AVP) for notebook CPU VR applications.
For engineers reviewing the TPS51610RHBT datasheet, TPS51610RHBT pinout, TPS51610RHBT application, or TPS51610RHBT equivalent, this device requires an active Intel CNDA agreement and targets high-density, low-voltage, fast-transient mobile processor power stages where phase interleaving, AVP compliance, and IMVP-specific telemetry are mandatory.
Technical Context
The TPS51610RHBT implements a dual-phase D-CAP2™ control architecture with independent loop compensation per phase, supporting both single- and dual-rail configurations. It integrates programmable AVP slope, VR ready signaling, and SVID 2.0-compliant serial interface for dynamic voltage/frequency scaling.
It features internal 5-V LDO bias supply, thermal shutdown with hysteresis, and overvoltage/undervoltage protection on VOUT. Phase shedding and diode emulation modes are supported for light-load efficiency optimization under IMVP-defined load-line constraints.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL95852IRZ-T | Single-phase controller with integrated drivers; lacks SVID 2.0 and AVP support. | Targeted at lower-power ULV CPUs (≤15 W TDP); not IMVP-8 certified. | Only suitable for non-IMVP or legacy mobile platforms lacking CPU telemetry requirements. |
| RT8803AGQW | Supports SVID but uses conventional voltage-mode control; no D-CAP2™ or AVP. | Used in cost-sensitive mainstream notebooks; requires external compensation and delivers slower transient response. | Appropriate when design prioritizes BOM cost over IMVP compliance and transient performance. |

FAQ
Is the TPS51610RHBT compatible with Intel 12th Gen Alder Lake processors?
Yes, the TPS51610RHBT supports Intel IMVP-8, which covers 11th and 12th Gen Core mobile processors including Alder Lake. It implements full SVID 2.0 communication, VR_READY handshake, and AVP profiles required for compatibility. Confirmation requires validation against Intel's latest IMVP-8 specification revision and use of TI's TPS51610RHBT-specific firmware configuration files.
Does the TPS51610RHBT require an Intel CNDA to be purchased or used?
Yes, the TPS51610RHBT is subject to Intel's confidentiality restrictions. End users must hold an active CNDA with Intel before accessing full documentation, reference designs, or application support. Aetrix Electronics provides logistics and traceable supply but does not grant CNDA rights; customers must obtain their own agreement via [email protected].
What is the function of Pin 33 on the TPS51610RHBT?
Pin 33 is the exposed thermal pad on the TPS51610RHBT VQFN package. It must be soldered to a dedicated PCB copper pour with thermal vias to ensure reliable heat dissipation and mechanical anchoring. Leaving Pin 33 unconnected violates TI's thermal design guidelines and risks premature failure under sustained 30-A+ phase current operation.
Can the TPS51610RHBT operate in single-phase mode?
Yes, the TPS51610RHBT supports configurable dual- or single-phase operation via SVID command or hardware strap. In single-phase mode, it drives one high-side/low-side MOSFET pair with full D-CAP2™ control and AVP, enabling flexible design reuse across different CPU TDP tiers while maintaining IMVP compliance for the TPS51610RHBT.
What package variant is the TPS51610RHBT supplied in?
The TPS51610RHBT is supplied in a 32-pin VQFN package (TI drawing RHB), measuring 5 mm × 5 mm with 0.5 mm pitch and 1 mm maximum height. It features wettable flanks and an exposed thermal pad (Pin 33), and is optimized for automated optical inspection and high-density notebook PCB layouts.
