Product details
Overview
MAX17039GTN+T from Maxim Integrated is a dual-output, VR12/IMVP-7-compliant step-down controller for CPU and GPU core power supplies, featuring a 3-phase + 1-phase Quick-PWM architecture with true differential voltage/current sensing, ±0.4% VOUT accuracy over line/load/temperature, 100kHz–600kHz programmable switching frequency per phase, and integrated boost switches in a 56-pin TQFN package.
For engineers reviewing the MAX17039GTN+T datasheet, MAX17039GTN+T pinout, MAX17039GTN+T application, or MAX17039GTN+T equivalent, key selection considerations include IMVP-7 SVID compliance, transient-phase overlap mode, active overshoot suppression, independent regulator A/B control, and external thermal-fault detection (VR_HOT#) support.
Technical Context
The MAX17039GTN+T implements two independent constant-on-time PWM controllers: Regulator A uses three-phase operation (two internal drivers + one external driver via MAX8791/MAX17491), supports transient-phase overlap and active overshoot suppression, and delivers precise load-line regulation via accurate lossless current balance and programmable active voltage positioning gain. Regulator B operates as a single-phase Quick-PWM controller with internal driver and full SVID interface control.
Both regulators comply with Intel VR12/IMVP-7 serial VID specifications at 25MHz, support individual pulse-skipping low-power states, soft-start/soft-shutdown, and coordinated fault response-shutting down both channels upon OVP/UVP/thermal fault detection. Remote sense capability ensures ±0.4% output accuracy across 4.5V–26V input range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Regulator Topology | Dual-output constant-on-time: 3-phase (Reg A) + 1-phase (Reg B) |
| Input Voltage Range | 4.5V to 26V - supports wide battery-input systems including notebooks and servers |
| Output Accuracy | ±0.4% over line, load, and temperature - enables tight CPU/GPU core voltage margins |
| Switching Frequency | 100kHz to 600kHz per phase - allows optimization of efficiency vs. size for each rail |
| SVID Interface | 25MHz Intel VR12/IMVP-7 compliant - enables dynamic VID code transitions and individual regulator control |

| Protection Features | OVP, UVP, thermal shutdown, phase-good fault detection - ensures coordinated channel shutdown on fault |
Pinout & Package
MAX17039GTN+T is housed in a lead-free, 56-pin, 7mm × 7mm TQFN package with exposed thermal pad (EP). Pin configuration follows Maxim's standard layout for VR12 controllers, with dedicated SVID bus pins (SCLK, SDATA), phase-driver outputs (PHASE_Ax, PHASE_B), remote sense inputs (VSNSA/B, GNSA/B), fault signals (VR_HOT#, PGOOD), and analog monitoring outputs (IMON_A/B).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PHASE_A1/A2/A3 | Regulator A high-side gate drive outputs | Drive synchronous MOSFETs for 3-phase CPU core; A1/A2 internal, A3 requires external driver (e.g., MAX8791) |
| PHASE_B | Regulator B high-side gate drive output | Drives single-phase GPU core synchronous rectifier with internal driver |
| VSNSA / GNSA | Regulator A remote voltage sense inputs | Enable Kelvin connection to CPU core for ±0.4% accuracy under high dI/dt load transients |
| VSNSB / GNSB | Regulator B remote voltage sense inputs | Enable Kelvin connection to GPU core, decoupling regulator B accuracy from PCB IR drop |
| SCLK / SDATA | Intel SVID 25MHz serial interface | Supports bidirectional VID code updates, pulse-skipping entry/exit, and VR__READY signaling |
| VR_HOT# | External thermal-fault open-drain output | Asserts low when external thermal sensor exceeds threshold - triggers coordinated shutdown |
Key Features
| Feature | Design Value |
|---|---|
| Transient-phase overlap mode | Reduces output capacitance requirement by accelerating phase activation during load steps |
| Active overshoot suppression | Minimizes peak VOUT excursion during fast load transients, lowering decoupling capacitor count |
| Programmable active voltage positioning gain | Enables precise droop slope tuning to match processor load-line requirements per VR12 spec |
| Lossless current balance sensing | Eliminates current-sense resistors in multiphase legs, improving efficiency and thermal performance |
| Individual regulator pulse-skipping control | Allows Reg A or Reg B to enter low-power state independently without affecting the other rail |
Applications
| High-Performance Notebook CPU Power | Discrete GPU Core Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output VR12/IMVP-7 controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL6367IRZ-T | Single-package dual 3+1-phase controller with integrated MOSFET drivers; no external driver required for third phase | Higher integration reduces board area but lacks VR_HOT# thermal-fault output | Preferred when minimizing external components outweighs need for external thermal monitoring |
| RT8803AZSP | Supports VR12.5/IMVP-8 with higher DAC resolution (9-bit); no transient-phase overlap or active overshoot suppression | Targets next-gen processors with tighter voltage positioning specs but reduced transient headroom | Chosen for IMVP-8 migration paths where legacy VR12 features like overshoot suppression are noncritical |
Compared with ISL6367IRZ-T and RT8803AZSP, the MAX17039GTN+T uniquely combines external thermal-fault signaling (VR_HOT#), transient-phase overlap, and active overshoot suppression-enabling lower output capacitance and thermally coordinated shutdown in space-constrained VR12 platforms.

FAQ
What is the function of the VR_HOT# pin on the MAX17039GTN+T?
The VR_HOT# pin on the MAX17039GTN+T is an open-drain thermal-fault output that asserts low when an external thermal sensor detects overheating. It triggers coordinated shutdown of both regulator A and B, ensuring system-level thermal safety. This signal is not internally generated-it requires connection to a compatible thermal monitor IC, and its behavior is defined in the MAX17039GTN+T datasheet Section 8.3.
Does the MAX17039GTN+T support independent enable/disable of Regulator A and Regulator B?
No-the MAX17039GTN+T does not support independent hardware enable/disable of Regulator A and B. Both regulators share the same EN pin and respond identically to enable signals. However, each regulator can be placed into a low-power pulse-skipping state via SVID commands, allowing software-controlled power gating without full shutdown of the MAX17039GTN+T.
Can the MAX17039GTN+T operate with only two phases on Regulator A?
Yes-the MAX17039GTN+T supports 2-phase operation for Regulator A using only the two internal drivers (PHASE_A1 and PHASE_A2), leaving the third phase (PHASE_A3) unconnected or disabled via configuration register. The external driver (e.g., MAX8791) is optional and only required when full 3-phase operation is needed for higher current delivery.
What is the purpose of the IMON_A and IMON_B outputs on the MAX17039GTN+T?
The IMON_A and IMON_B pins on the MAX17039GTN+T provide analog current-monitor outputs proportional to the load current of Regulator A and B, respectively. Each output delivers a 0–1V signal scaled to 1V per 50A (typical), enabling real-time current telemetry for system health monitoring and thermal management without adding external sense resistors.
How does the MAX17039GTN+T achieve ±0.4% output voltage accuracy?
The MAX17039GTN+T achieves ±0.4% output voltage accuracy through true differential remote sensing (VSNS/GNS inputs), an 8-bit IMVP-7 DAC with calibrated reference, and on-die temperature compensation circuitry. This accuracy is specified over full line (4.5V–26V), load (0–max), and temperature (–40°C to +105°C) ranges, as verified in Maxim's production test flow for the MAX17039GTN+T.
