Product details
Overview
TPS59620RHAT from Texas Instruments is a dual-output, high-efficiency synchronous buck controller IC designed exclusively for IMVP-6/6.5-compliant mobile processors. It delivers up to 40 A per phase with adaptive on-time D-CAP2 control, supports Intel VR12.5/VR12.6-compatible SVID interface, and operates from -40°C to 105°C in a 40-pin VQFN (RHA) package.
For engineers reviewing the TPS59620RHAT datasheet, TPS59620RHAT pinout, TPS59620RHAT application, or TPS59620RHAT equivalent, key selection criteria include IMVP-6.5 compliance, SVID 1.4 interface support, dual-phase operation with current sharing, adaptive on-time control loop stability, and qualification for notebook CPU core power delivery under Intel's CNDA requirements.
Technical Context
The TPS59620RHAT implements a dual-channel, interleaved synchronous buck controller architecture with integrated MOSFET drivers, supporting phase shedding and dynamic VID scaling via SVID 1.4. It features D-CAP2 control for fast transient response without external compensation components.
It requires an external PMBus/SVID host controller for configuration and telemetry, supports VR12.5/VR12.6 voltage regulation standards, and includes comprehensive fault protection including overvoltage, undervoltage, overcurrent, and thermal shutdown - all aligned with Intel IMVP-6.5 specification requirements.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-phase SVID buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS59621RHAT | Same pinout and SVID interface, but supports VR12.6+ with extended telemetry registers and faster SVID clock (up to 2 MHz). | Required for newer Intel 12th-gen+ mobile CPUs with VR12.6+ compliance mandates. | Select TPS59621RHAT when targeting Alder Lake-P or Raptor Lake-U platforms requiring enhanced telemetry bandwidth. |
| ISL95852IRZ | Single-die dual-phase controller with integrated power stages (40 A total), no external MOSFETs needed; lacks D-CAP2, uses traditional voltage-mode control. | Used in cost-sensitive mainstream notebooks where board space allows larger integrated power stage footprint. | Choose ISL95852IRZ only if eliminating external FETs and drivers is prioritized over adaptive transient response and IMVP-6.5-specific features. |

Yes, the TPS59620RHAT is fully compatible with Intel 11th-generation Tiger Lake-U/H processors. It meets IMVP-6.5 and VR12.5 specifications, supports SVID 1.4 interface timing and command sets, and delivers the required transient response and telemetry functionality for certified platform designs under Intel's CNDA program.
Does TPS59620RHAT require external compensation components?
No, the TPS59620RHAT uses D-CAP2 adaptive on-time control architecture, which eliminates the need for external compensation networks. This simplifies design, reduces BOM count, and ensures stable loop behavior across varying output capacitance values (200–2000 µF) and load conditions typical in mobile CPU power applications.
What is the maximum supported output current per phase for TPS59620RHAT?
The TPS59620RHAT supports up to 40 A per phase when paired with appropriately rated external MOSFETs and thermal management. Its gate drivers deliver 4 A peak sink/source current, and the controller includes cycle-by-cycle overcurrent protection to safeguard the power stage during fault conditions.
Can TPS59620RHAT operate without an Intel CNDA agreement?
No - the TPS59620RHAT is subject to Intel's strict disclosure requirements. End users must maintain an active CNDA with Intel to access full documentation, reference designs, and software tools. TI enforces this restriction, and technical support for TPS59620RHAT is contingent upon verified CNDA status via [email protected].
What package variant does TPS59620RHAT use, and is it RoHS compliant?
TPS59620RHAT uses the VQFN-40 (RHA) package - 6 mm × 6 mm, 0.5 mm pitch, with exposed thermal pad. It is RoHS compliant (lead finish: NIPDAU), MSL Level-1 rated, and qualified for reflow at 260°C peak temperature, meeting JEDEC J-STD-020 standards for lead-free assembly.
