Product details
Overview
TPS59640RSLR from Texas Instruments is a dual-output, high-efficiency, IMVP-6-compliant VRD11.1 voltage regulator controller designed specifically for Intel mobile processors. It supports 2-phase operation per output, delivers up to 60 A total output current, operates from -40°C to 105°C, and uses VQFN-48 (RSL) packaging. It enables precise core and I/O rail regulation in ultrabooks and thin-and-light notebooks.
For engineers reviewing the TPS59640RSLR datasheet, TPS59640RSLR pinout, TPS59640RSLR application, or TPS59640RSLR equivalent, key selection criteria include IMVP-6 compliance, dual 2-phase topology support, integrated MOSFET drivers, differential remote sensing, and Intel CNDA requirement for end-user deployment.
Technical Context
The TPS59640RSLR implements a dual-output, 2-phase-per-rail synchronous buck controller architecture with adaptive on-time D-CAP2™ control for fast transient response. It integrates gate drivers capable of driving high-side and low-side N-channel MOSFETs, supports differential remote voltage sensing on both outputs, and includes programmable overcurrent protection via RDS(on) sensing.
It features Intel VRD11.1/IMVP-6 protocol compliance including VID code decoding, thermal monitoring via PROCHOT#, and dynamic VID adjustment. The device requires a valid Intel CNDA for end-user access and does not support generic CPU power applications outside Intel mobile processor platforms.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output IMVP-6 voltage regulator controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS59641RSLR | Includes integrated 5-V LDO for auxiliary rail generation; otherwise identical pinout, specs, and IMVP-6 compliance | Required when system needs dedicated 5-V standby or always-on rail alongside main CPU rails | Select TPS59641RSLR only if auxiliary 5-V LDO functionality is needed; otherwise TPS59640RSLR is functionally sufficient |
| TPS51640ARSLR | IMVP-6 controller with -10°C to 105°C rating; lacks extended industrial temp range and PROCHOT# robustness enhancements of TPS59640RSLR | Targeted at consumer-grade notebooks where extended low-temp operation is not required | Use TPS51640ARSLR only in cost-sensitive consumer designs with ambient > -10°C; TPS59640RSLR required for industrial or wide-temp deployments |
Compared with TPS59641RSLR, TPS59640RSLR omits the integrated 5-V LDO but offers identical dual 2-phase control, IMVP-6 compliance, and -40°C operation-making it optimal for space-constrained designs where auxiliary rail is externally generated. Against TPS51640ARSLR, TPS59640RSLR adds guaranteed -40°C startup and enhanced thermal fault handling for mission-critical mobile platforms.

FAQ
Is TPS59640RSLR compatible with non-Intel processors?
No. The TPS59640RSLR is designed exclusively for Intel IMVP-6-compliant mobile processors under a strict disclosure agreement. It implements VRD11.1-specific signaling, VID decoding, and PROCHOT# handshake protocols that are not interoperable with AMD, ARM, or other vendor CPU platforms. End users must hold a current CNDA with Intel to deploy TPS59640RSLR in production systems.
What is the minimum operating temperature specification for TPS59640RSLR?
The TPS59640RSLR is rated for operation from -40°C to 105°C ambient temperature. This extended industrial temperature range enables reliable startup and regulation in cold-storage environments, outdoor kiosks, and automotive-adjacent portable computing applications where ambient temperatures may fall below -10°C - unlike the consumer-grade TPS51640ARSLR variant.
Does TPS59640RSLR require external compensation components?
No. The TPS59640RSLR uses TI's D-CAP2™ adaptive on-time control architecture, which eliminates the need for external loop compensation components. This simplifies PCB layout, reduces BOM count, and ensures stable regulation across all ceramic output capacitor types and values without tuning - a key advantage over voltage-mode or current-mode controllers requiring RC networks.
How many phases does TPS59640RSLR support per output rail?
The TPS59640RSLR supports two independent 2-phase outputs - four total power stages - enabling high-current delivery with interleaved switching to reduce input/output ripple and thermal stress. Each output (A and B) can be configured as a separate 2-phase rail, allowing flexible allocation between CPU core, GPU, or I/O domains without external phase doublers or controllers.
What package type and dimensions does TPS59640RSLR use?
TPS59640RSLR uses the VQFN-48 (RSL) package: 6 mm × 6 mm body size, 0.4 mm pin pitch, 1 mm maximum height, with an exposed thermal pad. It is supplied in large tape-and-reel format (2500 units per reel) and complies with JEDEC Level-1 moisture sensitivity and RoHS requirements.
