Product details
Overview
TPS59621RHAR from Texas Instruments is a dual-output, high-efficiency synchronous buck controller IC designed exclusively for Intel IMVP-6/6.5 mobile processor core and I/O power delivery. It supports 0.5–1.5 V output voltage range, 2-phase interleaved operation per rail, and integrated 5-bit DAC for dynamic VID control. Used in ultrabook and thin-and-light notebook platforms requiring strict Intel compliance.
For engineers reviewing the TPS59621RHAR datasheet, TPS59621RHAR pinout, TPS59621RHAR application, or TPS59621RHAR equivalent, key selection criteria include IMVP-6.5 VID protocol support, dual-rail phase interleaving capability, -40°C to +105°C operating temperature, QFN-40 (RHA) package with 0.5 mm pitch, and mandatory Intel CNDA agreement for deployment.
Technical Context
The TPS59621RHAR implements two independent synchronous buck controllers-one for CPU core (VCORE) and one for CPU I/O (VIO)-each supporting up to 2-phase interleaved operation. It embeds an Intel-compliant 5-bit VID interface with dynamic voltage identification timing aligned to IMVP-6.5 specifications.
It integrates programmable overvoltage/undervoltage protection, thermal monitoring via remote diode sensing, and adaptive on-time control with current-mode feedback. The device requires external gate drivers and power MOSFETs, and operates from a 5-V or 12-V input bus.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail IMVP-compliant buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS59622RHAR | Supports IMVP-7.0/7.1 with updated VID timing, higher max switching frequency (1.2 MHz vs. 1.0 MHz), and added SVID interface | Required for 8th-gen+ Intel Core processors; not backward-compatible with IMVP-6.5 VID timing | Select only when targeting Coffee Lake or newer CPUs; TPS59621RHAR remains optimal for Sandy Bridge through Haswell platforms |
| ISL95831IRZ | Single-chip dual-rail solution with integrated gate drivers and MOSFETs; no external FETs required; supports IMVP-6.5 but lacks remote diode sensing | Suitable for lower-cost, lower-power designs where board space is constrained and thermal monitoring is handled externally | Choose ISL95831IRZ for simplified BOM and layout; retain TPS59621RHAR when discrete FET selection, thermal feedback, or higher current scalability (>45 A/rail) is needed |
Compared with TPS59622RHAR and ISL95831IRZ, the TPS59621RHAR uniquely balances IMVP-6.5 compliance, external FET flexibility, and integrated thermal monitoring-making it the designated solution for validated Sandy Bridge through Haswell mobile reference designs.

FAQ
Is the TPS59621RHAR compatible with Intel 10th-generation processors?
No, the TPS59621RHAR is designed exclusively for Intel IMVP-6 and IMVP-6.5 platforms (Sandy Bridge through Haswell). It does not support IMVP-7.0 or later protocols used by 10th-gen and newer processors. For Comet Lake or Tiger Lake designs, TI recommends the TPS59622RHAR or TPS59633RHAR instead. Always verify compatibility against the target processor's VRD specification before selecting the TPS59621RHAR.
Does the TPS59621RHAR include integrated MOSFETs or gate drivers?
The TPS59621RHAR is a controller-only IC and does not integrate power MOSFETs or gate drivers. It provides high-side gate drive outputs (PHASE1A/B and PHASE2A/B) to drive external N-channel MOSFETs or DrMOS modules. This architecture enables system-level optimization of efficiency, thermal performance, and current capacity beyond what integrated solutions offer.
What is required to legally use the TPS59621RHAR in a product?
To use the TPS59621RHAR, the end user must hold a current Confidentiality and Non-Disclosure Agreement (CNDA) with Intel, as the device implements proprietary IMVP-6.5 voltage regulation algorithms and timing. TI requires proof of active CNDA status before releasing full design resources. Contact [email protected] for verification and onboarding.
What package variant is the TPS59621RHAR shipped in?
The TPS59621RHAR is supplied in a VQFN-40 (RHA) package: 6 mm × 6 mm body, 0.5 mm pitch, 1 mm maximum height, with an exposed thermal pad. It ships in large tape-and-reel format (2500 units per reel) and carries MSL Level-3 moisture sensitivity rating (260°C, 168-hour floor life).
Can the TPS59621RHAR be used without Intel's VID interface?
No-the TPS59621RHAR relies entirely on the 5-bit parallel VID interface for output voltage setting and sequencing; it has no internal DAC or resistor-programmable feedback. Operation outside Intel IMVP-6.5 systems is not supported. Fixed-voltage or non-VID applications require alternative controllers such as the TPS546D24 or LM27402.
