Product details
Overview
MAX17030GTL+T from Maxim Integrated is a 3/2-phase interleaved Quick-PWM™ step-down VID controller for IMVP-6.5 notebook CPU core power supplies, supporting direct battery-to-core conversion with 7V–26V input, ±0.5% VOUT accuracy over line/load/temperature, and integrated dual gate drivers. It enables active voltage positioning, dynamic phase selection, and lossless current balance in high-current mobile computing applications.
For engineers reviewing the MAX17030GTL+T datasheet, MAX17030GTL+T pinout, MAX17030GTL+T application, or MAX17030GTL+T equivalent, this page delivers verified technical context, confirmed pin functions, real-world IMVP-6.5 compliance details, and validated alternative options for notebook CPU VR design.
Technical Context
The MAX17030GTL+T implements a triple/dual-phase Quick-PWM control architecture with true out-of-phase operation to reduce input/output ripple, supports IMVP-6.5 VID protocol via 7-bit DAC, and integrates two internal high-current gate drivers (DH1/DL1, DH2/DL2) plus PWM3 output for external third-phase drive. It features programmable slew-rate control via TIME pin and thermistor-based thermal monitoring at THRM.
Its active voltage positioning adjusts output voltage downward under load to minimize power dissipation and bulk capacitance, while lossless current sensing across CSP/CSN inputs enables accurate per-phase current monitoring and valley-current limiting. The device operates across -40°C to +105°C and complies with IMVP-6.5 power sequencing and timing requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 7V to 26V - supports direct bucking from 3–4 Li+ cells without intermediate regulation. |
| VOUT Accuracy | ±0.5% over line, load, and temperature - ensures stable CPU core voltage under dynamic load and thermal variation. |
| Phase Configuration | Configurable 2- or 3-phase interleaved operation - reduces ripple current stress on input capacitors and eases EMI filtering. |
| Switching Frequency | Up to 600kHz per phase - enables compact magnetics and high transient response in space-constrained notebooks. |
| VID Interface | 7-bit IMVP-6.5-compliant DAC - provides precise, digitally controlled output voltage scaling for Intel SV/XE processors. |
| Current Sensing | Lossless per-phase sensing via CSP/CSN inputs - enables accurate current balance, valley-current limit, and IMON analog monitor output. |
| Thermal Protection | Programmable VRHOT trip at 30% of VCC (±1%) - triggers fault signaling when thermistor divider indicates critical junction temperature. |
Pinout & Package
MAX17030GTL+T is housed in a 40-pin Thin QFN package (5mm × 5mm) with exposed pad for thermal management. Pin numbering follows top-view layout as specified in Maxim's datasheet revision 1 (8/09).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB / FBAC | Feedback and droop amplifier output | FB compares regulated output to VID-slewed target; FBAC sets AC droop gain for transient stability and current sharing. |
| CSP1–CSP3 / CSN1–CSN3 | Per-phase current sense differential inputs | Enable lossless current monitoring and balancing across up to three phases; CSP3/CSN3 disable phase 3 when tied to VCC/GND. |
| DH1/DL1, DH2/DL2, PWM3 | Gate drive outputs | DH/DL pairs drive synchronous rectifier FETs for phases 1 and 2; PWM3 drives external third-phase driver (e.g., MAX8791). |
| TIME / ILIM | Slew-rate and current-limit programming | TIME sets VID transition slew rate via RTIME resistor; ILIM adjusts valley current limit threshold with 10× scaling (e.g., 225mV → 22.5mV). |
| THRM / VRHOT | Thermal sensing and fault output | THRM accepts thermistor-divider voltage; VRHOT asserts low when temperature exceeds programmed threshold (30% VCC). |
| IMON / PWRGD / CLKEN | Monitor and status outputs | IMON provides analog current sum proportional to total load; PWRGD signals valid VOUT; CLKEN enables CPU clock upon regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Triple/dual-phase Quick-PWM control | Enables instantaneous load-step response and seamless transition between PWM/skip modes for optimal light/heavy-load efficiency. |
| Active voltage positioning (AVP) | Reduces output voltage under load to cut I²R losses and shrink required bulk capacitance-supports tantalum, polymer, or ceramic output caps. |
| Dynamic phase selection | Automatically disables unused phases during light-load states to maintain high efficiency in sleep/idle modes per IMVP-6.5 specification. |
| Integrated boost switches | Eliminates need for external BST diodes; supports self-biased high-side gate drive for synchronous FETs across all phases. |
| Remote sense with GNDS compensation | GNDS input compensates for PCB trace resistance, enabling accurate regulation at CPU socket despite IR drop in power delivery path. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-phase IMVP-6.5 voltage regulator controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX17036GTL+T | Includes transient suppression feature; otherwise identical pinout, specs, and IMVP-6.5 compliance. | Preferred for designs requiring enhanced load-step immunity in high-dI/dt CPU workloads (e.g., AVX-heavy compute). | Select MAX17036GTL+T when transient suppression is required; MAX17030GTL+T remains optimal for cost-sensitive, standard IMVP-6.5 implementations. |
| ISL6367CRZ-T | 6-phase capable, supports IMVP-7/7.5; higher max switching frequency (1MHz); no integrated BST switches. | Targets next-gen CPUs beyond IMVP-6.5; requires external BST diodes and more complex layout for 6-phase operation. | Choose ISL6367CRZ-T only for future-proofing or IMVP-7 migration; not drop-in compatible due to pin count, phase count, and BST architecture differences. |
Compared with MAX17036GTL+T, the MAX17030GTL+T omits transient suppression but offers identical efficiency, accuracy, and thermal protection-making it ideal for cost-optimized notebook VRMs. Versus ISL6367CRZ-T, MAX17030GTL+T provides simpler integration, lower BOM count, and proven IMVP-6.5 compliance without overengineering.

FAQ
What is the primary function of the MAX17030GTL+T in a notebook power system?
The MAX17030GTL+T serves as a 2-/3-phase Quick-PWM™ step-down VID controller for IMVP-6.5 CPU core supplies. It directly converts battery voltage (7V–26V) to precise core voltages (e.g., 0.8125V–1.5V), manages dynamic phase shedding, enforces active voltage positioning, and provides accurate current monitoring via its CSP/CSN inputs-all within a single 40-pin QFN package.
Does the MAX17030GTL+T support 3-phase operation out of the box?
Yes-the MAX17030GTL+T natively supports 3-phase operation using its two integrated gate drivers (DH1/DL1, DH2/DL2) and PWM3 output, which drives an external third-phase driver like the MAX8791. Phase 3 is enabled by default; it can be disabled by strapping CSP3 to VCC and CSN3 to GND, making the MAX17030GTL+T field-configurable for 2- or 3-phase use.
How does the MAX17030GTL+T achieve ±0.5% VOUT accuracy?
The MAX17030GTL+T achieves ±0.5% VOUT accuracy through a combination of high-precision 7-bit IMVP-6.5 DAC, matched internal resistors in its feedback error amplifier, remote sensing via GNDS compensation, and tight process-controlled transconductance in FBAC and IMON paths. This accuracy is guaranteed over -40°C to +105°C, line, and load conditions per Maxim's datasheet specifications.
Can the MAX17030GTL+T be used in server or desktop applications?
Yes-the MAX17030GTL+T is qualified for -40°C to +105°C operation and supports robust protections (OVP/UVP/thermal fault) required in desktop and entry-level server CPU VRMs. Its 7V–26V input range, 600kHz max switching frequency, and 3-phase scalability make it suitable for compact, high-efficiency VRMs in non-mobile platforms where IMVP-6.5 compliance is acceptable.
What is the role of the TIME pin on the MAX17030GTL+T?
The TIME pin on the MAX17030GTL+T sets the slew rate for VID code transitions using an external resistor (RTIME). It controls how quickly the output voltage ramps during boot, shutdown, and dynamic VID changes-critical for meeting IMVP-6.5 timing requirements and preventing CPU reset due to excessive dV/dt. The nominal slew rate is (12.5mV/μs) × (71.5k/RTIME), with startup/shutdown operating at ¼ of normal rate.
