Product details
Overview
TPS59641RSLR from Texas Instruments is a dual-output, 3-phase VR12.5/IMVP7-compliant CPU power controller IC designed for high-efficiency mobile processor core and I/O voltage regulation. It supports up to 3+1 phase operation, delivers ≤1% output voltage accuracy, operates across –40°C to +105°C, and integrates PMBus 1.2 interface for dynamic voltage scaling and telemetry. It is deployed in ultrabook and thin-and-light laptop platforms.
For engineers reviewing the TPS59641RSLR datasheet, TPS59641RSLR pinout, TPS59641RSLR application, or TPS59641RSLR equivalent, key selection criteria include IMVP7 compliance, 3-phase interleaved control architecture, PMBus programmability, thermal performance in VQFN-48 (RSL), and Intel CNDA requirement for deployment.
Technical Context
The TPS59641RSLR implements a digital multi-phase PWM controller with integrated gate drivers, supporting VR12.5/IMVP7 protocols via SMBus/PMBus 1.2. It features adaptive voltage positioning (AVP), differential remote sensing, and real-time current balancing across up to three phases for the core rail and one dedicated phase for the I/O rail.
It uses a 48-pin VQFN (RSL) package with 0.4 mm pitch and 6 mm × 6 mm footprint, rated for –40°C to +105°C operation. The device requires an active Intel CNDA agreement for use and does not support generic CPU power applications outside IMVP7-compliant mobile processors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPU power controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS59640RSLR | VR12.5-only (no IMVP7 support); lacks SVID v3.0 features and extended telemetry registers | Restricted to older Intel mobile platforms (e.g., Sandy Bridge–Haswell); no CNDA requirement | Select when targeting legacy IMVP6/VR12 platforms without need for IMVP7 dynamic features |
| TPS51640ARSLR | VR12-compliant only; no IMVP7 or SVID v3.0; lower phase count (2+1) and reduced PMBus command set | Designed for mid-tier mobile CPUs (e.g., Pentium/Celeron); excludes advanced thermal management and AVP tuning | Choose for cost-sensitive designs where full IMVP7 feature set and 3-phase core capability are unnecessary |
Compared with TPS59640RSLR and TPS51640ARSLR, the TPS59641RSLR uniquely enables IMVP7-compliant dynamic voltage/frequency scaling, full SVID v3.0 support, and 3-phase core rail control-making it mandatory for post-2018 Intel Core mobile processors requiring CNDA-governed power delivery.

FAQ
Is the TPS59641RSLR compatible with non-Intel processors?
No. The TPS59641RSLR is explicitly designed for Intel IMVP7-compliant mobile processors and requires a valid CNDA with Intel for legal deployment. Its SVID v3.0 interface, AVP algorithm, and VR12.5 timing parameters are not interoperable with AMD, ARM, or generic CPU power architectures. Use outside Intel's approved ecosystem violates licensing terms and may result in unstable operation.
What is the significance of the "RSLR" suffix in TPS59641RSLR?
The "RSLR" suffix denotes the VQFN-48 package variant (RSL drawing code) in large tape-and-reel format (2500 units per reel). This matches TI's standardized packaging nomenclature: RSL = 6 mm × 6 mm VQFN with 0.4 mm pitch and wettable flanks; R = large reel (2500 pcs); T = small reel (250 pcs). The TPS59641RSLR is identical in silicon and functionality to TPS59641RSLRG4 and TPS59641RSLT, differing only in packaging and reel size.
Does the TPS59641RSLR require external gate drivers?
No. The TPS59641RSLR integrates high-current MOSFET gate drivers capable of directly driving high-side and low-side N-channel FETs for all three core phases and the single I/O phase. Each PHASEx output delivers ≥1 A peak sink/source current with adjustable dead-time control, eliminating the need for external drivers in typical 3+1 phase notebook designs.
Can the TPS59641RSLR be used without PMBus communication?
Yes-but with critical limitations. The TPS59641RSLR supports hardware-defined default VID tables and basic enable/PGOOD sequencing without PMBus. However, full IMVP7 compliance-including dynamic VID updates, AVP coefficient programming, telemetry readback, and thermal event response-requires active PMBus 1.2 communication. Designs omitting PMBus forfeit Intel certification and lose adaptive voltage control.
What thermal management features does the TPS59641RSLR provide?
The TPS59641RSLR includes on-die temperature monitoring with programmable thermal warning and shutdown thresholds, plus PMBus-accessible die temperature reporting. It supports Intel's PROCHOT# protocol for coordinated CPU/GPU throttling and enables AVP-based voltage reduction under thermal stress. Its VQFN-48 (RSL) package features an exposed thermal pad optimized for PCB copper thermal vias, achieving ≤35°C/W junction-to-board thermal resistance in standard 4-layer layouts.
