Product details
Overview
TPS51610RHBR from Texas Instruments is a dual-phase, synchronous buck controller IC designed exclusively for IMVP-7/8 mobile CPU core power delivery in ultrabooks and thin-and-light notebooks. It supports 0.25–1.5 V output with ±0.5% regulation accuracy, 500 kHz–1.5 MHz programmable switching frequency, and integrated gate drivers for high-side and low-side MOSFETs. Its primary role is VR12.5/IMVP-7 compliant voltage regulation at the processor die interface.
For engineers reviewing the TPS51610RHBR datasheet, TPS51610RHBR pinout, TPS51610RHBR application, or TPS51610RHBR equivalent, key selection criteria include IMVP-7/8 compliance, dual-phase phase-interleaved control, adaptive on-time D-CAP2™ architecture, and support for Intel's SVID v3.0 serial voltage identification interface.
Technical Context
The TPS51610RHBR implements a D-CAP2™ adaptive on-time control loop with internal compensation, enabling fast transient response without external loop components. It integrates two independent PWM controllers with 180° phase interleaving to reduce input/output ripple and improve thermal distribution across phases.
SVID v3.0 communication enables dynamic voltage scaling, telemetry reporting (VOUT, IOUT, temperature), and fault status via a 4-wire serial bus. The device requires an Intel CNDA agreement for full access to configuration registers and application guidance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-phase IMVP-compliant voltage regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL95852IRZ | Single-chip dual-phase controller with integrated MOSFET drivers; supports IMVP-7 but not SVID v3.0 telemetry | Lacks real-time current/temperature reporting; requires external ADC for telemetry | Choose when SVID v3.0 telemetry is not required and cost sensitivity outweighs telemetry needs |
| RT8806AZQW | Supports SVID v3.0 and dual-phase control but uses fixed-frequency PWM (not D-CAP2™); no adaptive on-time | Slower transient response (~3 µs vs. <1 µs); higher external component count for loop stability | Prefer when fixed-frequency EMI control is prioritized over ultra-fast load-step response |
Compared with ISL95852IRZ and RT8806AZQW, the TPS51610RHBR uniquely combines D-CAP2™ adaptive on-time control, full SVID v3.0 telemetry, and IMVP-8 compliance-enabling tighter voltage regulation, faster transient recovery, and firmware-integrated thermal management in next-gen mobile platforms.

FAQ
Is the TPS51610RHBR compatible with Intel's latest IMVP-8 specification?
Yes, the TPS51610RHBR is fully compliant with IMVP-8 specifications, including VR ready signaling, phase shedding, and SVID v3.0 command set. It supports all mandatory IMVP-8 timing and protocol requirements for mobile CPU core power delivery. TI validates TPS51610RHBR against Intel's IMVP-8 compliance test plan under active CNDA agreements.
Does the TPS51610RHBR require external compensation components?
No, the TPS51610RHBR uses D-CAP2™ adaptive on-time control architecture, which eliminates the need for external loop compensation components such as type-II or type-III compensators. This simplifies design, reduces BOM count, and ensures stable operation across load and temperature without manual tuning.
What is the function of Pin 33 on the TPS51610RHBR?
Pin 33 is the exposed thermal pad on the TPS51610RHBR VQFN package. It is not electrically connected but must be soldered to a dedicated PCB thermal pad for effective heat dissipation and mechanical reliability. TI specifies minimum 75% solder coverage and recommends vias filled or tented beneath the pad for optimal thermal performance.
Can the TPS51610RHBR operate without an Intel CNDA agreement?
No-the TPS51610RHBR is subject to Intel's strict disclosure requirements. End users must hold a current CNDA agreement with Intel to access full configuration registers, application notes, and validation test reports. TI provides basic datasheets publicly, but full design enablement requires CNDA verification through [email protected].
What switching frequency range does the TPS51610RHBR support, and how is it set?
The TPS51610RHBR supports a programmable switching frequency from 500 kHz to 1.5 MHz, configured via external resistor on the FREQ pin. This allows designers to balance efficiency (lower frequency) versus size (higher frequency) based on inductor and capacitor selection. Frequency setting is non-volatile and retained across power cycles.
