Product details
Overview
The MAX17030GTL+ from Maxim Integrated is a 3/2-phase interleaved Quick-PWM™ step-down VID controller for IMVP-6.5 notebook CPU core power supplies, featuring ±0.5% VOUT accuracy over line/load/temperature, integrated dual gate drivers, and support for external third-phase drive via PWM3/DRSKP outputs. It operates from a 7V–26V battery input and delivers active voltage positioning for reduced bulk capacitance in high-current laptop VRMs.
For engineers reviewing the MAX17030GTL+ datasheet, MAX17030GTL+ pinout, MAX17030GTL+ application, or MAX17030GTL+ equivalent, key selection criteria include IMVP-6.5 compliance, triple-phase dynamic phase selection, lossless current balance across up to three phases, and thermistor-based thermal fault protection with VRHOT output.
Technical Context
The MAX17030GTL+ implements true out-of-phase interleaving across two internal phases (LX1/LX2) plus an optional third phase driven externally (e.g., via MAX8791), reducing input ripple current and output voltage ripple. Its Quick-PWM architecture enables instantaneous response to fast load transients while maintaining stable regulation during VID code transitions.
It integrates a 7-bit IMVP-6.5 DAC, slew-rate-controlled VID transitions via the TIME pin, remote sense (FB/GNDS), and analog current monitoring (IMON) proportional to total inductor current sum. Active voltage positioning adjusts output droop dynamically using FBAC feedback with programmable gain (0.97–1.03 V/V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 7V to 26V - supports direct buck conversion from 3–4 Li+ cells without intermediate stage. |
| VOUT Accuracy | ±0.5% over line/load/temperature - ensures tight CPU core voltage regulation under dynamic conditions. |
| Phase Support | 2 internal + 1 external phase - enables flexible 2- or 3-phase configurations per CPU requirement. |
| Switching Frequency | Up to 600kHz per phase - balances efficiency, component size, and transient response. |
| Current Sensing | Lossless valley current limit with ±4mV negative threshold accuracy - enables precise per-phase overcurrent protection. |
| Thermal Protection | VRHOT trip at 30% of VCC (29–31%) with 75mV hysteresis - provides programmable thermal shutdown based on thermistor divider. |
| Output Monitoring | IMON analog output with 1.6mS transconductance - delivers linear current-sum signal for system telemetry or closed-loop control. |
Pinout & Package
MAX17030GTL+ is housed in a 40-pin Thin QFN (TQFN-EP) package measuring 5mm × 5mm with exposed pad for thermal dissipation. Pin functions are validated per Maxim's official datasheet Rev 1 (8/09).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CSN1–CSN3 / CSP1–CSP3 | Per-phase current-sense differential inputs | Enable lossless valley current sensing and balancing across all enabled phases; CSP3/CSN3 disable phase 3 when tied to VCC/GND. |
| DH1/DH2/PWM3 | High-side gate drive outputs | Drive synchronous rectifier FETs; DH1/DH2 integrate drivers, PWM3 supports external third-phase driver (e.g., MAX8791). |
| DL1/DL2/DRSKP | Low-side gate drive outputs | Provide complementary low-side drive; DRSKP enables skip-mode control for light-load efficiency optimization. |
| FB / FBAC / GNDS | Feedback and voltage-positioning nodes | FB is main error amplifier input; FBAC sets AC droop; GNDS enables remote output sensing with 0.95–1.05 V/V gain tolerance. |
| THRM / VRHOT | Thermal monitoring interface | THRM accepts thermistor-divider voltage; VRHOT asserts open-drain fault signal when THRM falls below 30% of VCC. |
| IMON / ILIM / TIME | Current monitor, limit adjust, slew control | IMON outputs analog current sum; ILIM sets valley current limit threshold (20–25mV); TIME configures VID transition slew rate (35.7k–178kΩ). |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Phase Selection | Automatically enables/disables phases based on load demand to optimize efficiency in both active and sleep states. |
| Transient Phase Overlap | Reduces required output capacitance by overlapping phase activation during load steps, improving transient response. |
| Active Voltage Positioning | Adjustable droop gain (0.97–1.05 V/V) compensates for IR drop across PCB traces and enables optimal capacitor selection (tantalum/polymer/ceramic). |
| Integrated Boost Switches | On-chip BST1/BST2 switches eliminate need for external bootstrap diodes, simplifying layout and improving reliability. |
| Programmable Slew-Rate Control | TIME pin resistor sets VID transition speed (1.25–25 mV/μs), preventing overshoot/undershoot during voltage changes. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-phase VID controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX17036GTL+ | Includes transient suppression feature; otherwise identical pinout, specs, and IMVP-6.5 compliance. | Preferred for designs requiring enhanced immunity to fast load transients beyond standard IMVP-6.5 spec. | Select MAX17036GTL+ only if transient suppression is explicitly required; MAX17030GTL+ suffices for baseline IMVP-6.5 compliance. |
| ISL95210IRZ | 3-phase controller with integrated MOSFET drivers, 4.5–26V VIN, but uses Intel VR12.5/VR12.6 protocol-not IMVP-6.5. | Targets newer Intel platforms (e.g., 4th-gen Core); lacks IMVP-6.5 power sequencing and VID timing compliance. | Not interchangeable without firmware and layout changes; use only for VR12.5/VR12.6-based systems. |
Compared with MAX17036GTL+, the MAX17030GTL+ omits transient suppression but retains identical phase control, accuracy, and thermal protection-making it the cost-optimized choice for standard IMVP-6.5 notebooks. ISL95210IRZ requires full platform requalification due to protocol incompatibility.

FAQ
What is the input voltage range supported by the MAX17030GTL+?
The MAX17030GTL+ supports a 7V to 26V input voltage range, enabling direct step-down from 3–4 series Li+ battery packs without intermediate regulation. This wide range accommodates varying battery states of charge and ensures robust operation across full discharge cycles in notebook applications.
Does the MAX17030GTL+ support IMVP-6.5 power sequencing requirements?
Yes, the MAX17030GTL+ is fully compliant with IMVP-6.5 power sequencing and timing specifications, including precise CLKEN startup delay (20–100μs), PWRGD assertion timing, and VID code transition blanking (20μs). It meets all mandatory timing windows defined in the IMVP-6.5 specification for SV and XE core supplies.
How does the MAX17030GTL+ implement current balancing across multiple phases?
The MAX17030GTL+ achieves lossless current balance using per-phase CSP/CSN differential inputs and a droop amplifier with 390–407μS transconductance. It sums inductor currents digitally and adjusts duty cycles in real time to maintain ≤0.2mV imbalance across phases at full load, as verified in typical operating characteristics.
Can the MAX17030GTL+ operate with only two phases enabled?
Yes, the MAX17030GTL+ natively supports dual-phase operation. Phases 2 and 3 can be disabled independently by tying CSP2/CSP3 to VCC and CSN2/CSN3 to GND. The controller automatically configures for 1- or 2-phase mode while retaining full Quick-PWM control, current monitoring, and protection features.
What is the function of the TIME pin on the MAX17030GTL+?
The TIME pin on the MAX17030GTL+ sets the slew rate for VID code transitions using an external resistor (35.7kΩ–178kΩ). It controls voltage ramp speed during boot, shutdown, and dynamic VID changes-preventing overshoot/undershoot and ensuring stable CPU voltage transitions per IMVP-6.5 timing requirements.
