Texas Instruments TPS59620RHAR

Overview

TPS59620RHAR from Texas Instruments is a dual-output, high-efficiency, synchronous buck controller IC designed exclusively for IMVP-6/6.5-compliant mobile processors under Intel's confidential disclosure agreement. It delivers up to 40 A per phase with adaptive on-time D-CAP2 control, supports VR12.5/IMVP-6.5 serial VID interface, and operates from -40°C to 105°C in a 40-pin VQFN (RHA) package.

For engineers reviewing the TPS59620RHAR datasheet, TPS59620RHAR pinout, TPS59620RHAR application, or TPS59620RHAR equivalent, key selection considerations include IMVP-6.5 compliance, dual-phase synchronous buck topology, D-CAP2 transient response, VR12.5 serial VID interface support, and thermal performance in thin-profile mobile platforms.

Technical Context

The TPS59620RHAR implements a two-phase, interleaved synchronous buck controller architecture with integrated gate drivers and adaptive on-time D-CAP2 modulation. It supports Intel's VR12.5/IMVP-6.5 serial voltage identification (VID) protocol for dynamic output voltage scaling and includes programmable over-current protection via RDS(on) sensing.

It features a dedicated PMBus-compatible SMBus interface for telemetry (VOUT, IOUT, temperature), configurable phase shedding, and precision remote sensing with differential amplifier inputs. The device requires external MOSFETs and supports 3–24 V input range with output voltages down to 0.3 V.

FAQ

Is the TPS59620RHAR approved for use with Intel 12th Gen Core processors?

Yes, the TPS59620RHAR is fully compliant with Intel's IMVP-6.5 specification and qualified for use with 12th Gen Intel Core mobile processors (Alder Lake-P/H series). It supports VR12.5 serial VID commands, dynamic voltage scaling, and telemetry required by these CPUs. Use requires an active CNDA with Intel and adherence to TI's IMVP licensing terms.

Does the TPS59620RHAR integrate MOSFET drivers?

Yes, the TPS59620RHAR integrates dual high-current gate drivers capable of sourcing/sinking 1.5 A per phase. These drivers directly control external high-side and low-side N-channel MOSFETs. No external driver ICs are needed, though discrete MOSFET selection must match the controller's 1.2 MHz max switching frequency and thermal limits.

What is the purpose of the SMBCLK and SMBDAT pins on the TPS59620RHAR?

The SMBCLK and SMBDAT pins implement a PMBus-compatible SMBus 2.0 interface used for VR12.5/IMVP-6.5 serial VID communication. They allow the host processor or chipset to dynamically program output voltage, read real-time telemetry (VOUT, IOUT, temperature), configure protection thresholds, and manage power states - all without requiring additional GPIO or analog interfaces.

Can the TPS59620RHAR operate without a CNDA agreement with Intel?

No. The TPS59620RHAR is subject to Intel's IMVP confidentiality requirements. End users must maintain an active Confidentiality Disclosure Agreement (CNDA) with Intel before designing in or deploying the TPS59620RHAR. TI enforces this restriction through licensing terms and documentation access controls.

What thermal management features does the TPS59620RHAR include?

The TPS59620RHAR includes junction temperature monitoring via internal diode, programmable thermal warning (THERM), and automatic thermal shutdown at 155°C with 10°C hysteresis. Its VQFN-40 (RHA) package features an exposed thermal pad that must be soldered to a PCB copper pour for effective heat dissipation - enabling reliable operation up to 105°C ambient in high-power mobile applications.
