Product details
Overview
TPS59610RHBR from Texas Instruments is a dual-phase, synchronous buck controller IC designed exclusively for Intel IMVP-6/6.5 mobile processor core power delivery. It supports 0.7–1.5 V output with ±0.5% DC accuracy, 600 kHz switching frequency, and integrated MOSFET drivers for high-efficiency VR11.x-compliant voltage regulation in ultrabooks and thin-and-light notebooks.
For engineers reviewing the TPS59610RHBR datasheet, TPS59610RHBR pinout, TPS59610RHBR application, or TPS59610RHBR equivalent, key selection considerations include IMVP-6/6.5 compliance, dual-phase phase-interleaved operation, adaptive on-time control, VRD/IMVP-specific telemetry interface, and thermal management via exposed pad soldering.
Technical Context
The TPS59610RHBR implements adaptive on-time (AOT) control architecture with phase interleaving to reduce input/output ripple and improve transient response. It integrates two independent gate drivers with programmable dead-time and shoot-through protection, supporting external N-channel MOSFETs in dual-phase configuration.
It features Intel VRD/IMVP-6.5-compliant serial VID interface, SVID-compatible telemetry reporting (VOUT, IOUT, temperature), and comprehensive fault protection including overvoltage, undervoltage, overcurrent, and thermal shutdown - all configured via dedicated pins and register mapping per Intel specification.

FAQ
Is the TPS59610RHBR compatible with Intel IMVP-6.5 specifications?
Yes, the TPS59610RHBR is fully compliant with Intel IMVP-6.5 specifications, including SVID protocol timing, VID code mapping, telemetry reporting format, and VRD11.0 electrical requirements. It was developed under Intel's CNDA and validated for use in certified mobile platforms. The TPS59610RHBR implements all mandatory IMVP-6.5 features such as adaptive voltage positioning, phase shedding, and thermal monitoring interface.
What is the recommended PCB layout practice for the TPS59610RHBR thermal pad?
The TPS59610RHBR's exposed thermal pad (Pin 33) must be soldered to a dedicated PCB copper pour connected to internal ground and/or thermal planes. TI recommends ≥75% solder paste coverage, 28–32 thermal vias (0.3 mm diameter, filled/plugged), and symmetric land pattern matching the 4.0 mm × 4.0 mm pad. This ensures junction-to-board thermal resistance ≤4.5°C/W and mechanical reliability per JEDEC J-STD-020.
Does the TPS59610RHBR support phase shedding for light-load efficiency?
Yes, the TPS59610RHBR supports automatic single-phase operation under light-load conditions via its IMVP-6.5-compliant phase shedding function. When output current drops below programmable threshold (~5 A), the controller disables one phase and adjusts switching frequency to maintain regulation while reducing gate drive and conduction losses. This feature is enabled by default and configurable via SVID command.
Can the TPS59610RHBR be used with non-Intel processors?
No - the TPS59610RHBR is designed exclusively for Intel IMVP-6/6.5 mobile processors under strict Intel CNDA terms. Its SVID interface, telemetry registers, and control algorithms are hardcoded to Intel's VRD11.0 specification. It lacks generic PWM or analog control modes and is not supported for AMD, ARM, or other processor families. Use requires active Intel CNDA agreement.
What is the maximum output current capability of the TPS59610RHBR?
The TPS59610RHBR itself does not define maximum current; it drives external N-channel MOSFETs. With appropriate FET selection (e.g., CSD18532KCS + CSD18533KCS per phase), the TPS59610RHBR-based solution delivers up to 60 A continuous output (30 A per phase) with <5°C junction rise at 105°C ambient. Current limit is set via ILIM pin voltage and sensed through RDS(on) or dedicated current-sense resistors.
