Product details
Overview
The MAX17036GTL+ from Maxim Integrated is a 3/2-phase interleaved Quick-PWM™ step-down VID power-supply controller compliant with IMVP-6.5 for notebook CPU core voltage regulation. It features ±0.5% VOUT accuracy over line/load/temperature, integrated dual gate drivers, and transient suppression - enabling high-efficiency direct battery-to-core conversion from 7V–26V inputs in high-current mobile computing systems.
For engineers reviewing the MAX17036GTL+ datasheet, MAX17036GTL+ pinout, MAX17036GTL+ application, or MAX17036GTL+ equivalent, this page delivers verified technical context, confirmed pin functions, IMVP-6.5 timing-compliant sequencing details, and validated alternative options for notebook SV/XE core power designs requiring active voltage positioning and lossless current balance.
Technical Context
The MAX17036GTL+ implements a triple/dual-phase Quick-PWM architecture with true out-of-phase operation to reduce input/output ripple and ease layout constraints. Its 7-bit IMVP-6.5 DAC interfaces directly with Intel CPUs, while dynamic phase selection optimizes efficiency across active and sleep states.
It integrates two internal high-side/low-side drivers (DH1/DL1, DH2/DL2), supports external third-phase drive via PWM3/DRSKP, and includes dedicated circuitry for active voltage positioning, slew-rate-controlled VID transitions, and thermistor-based thermal protection with VRHOT output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 7V to 26V - enables direct buck conversion from 3–4 Li+ cells without intermediate pre-regulation. |
| VOUT Accuracy | ±0.5% over line/load/temperature - ensures stable CPU core voltage under dynamic load and thermal variation. |
| Phase Configuration | Configurable 2- or 3-phase operation - supports flexible scaling for SV/XE CPU current demands up to ~60A. |
| Switching Frequency | Up to 600kHz per phase - balances efficiency, component size, and transient response in compact notebooks. |
| IMVP-6.5 Compliance | Full power sequencing, timing, and VID code mapping - guarantees interoperability with Intel 45nm/32nm mobile processors. |
| Transient Suppression | MAX17036-specific feature - reduces required bulk capacitance during fast load steps by overlapping phase activation. |
| Current Monitoring | Analog IMON output proportional to total inductor current - enables real-time CPU load telemetry without external ADC. |
Pinout & Package
Package: 40-pin Thin QFN (5mm × 5mm) with exposed pad (TQFN-EP), rated for -40°C to +105°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CSN3 / CSP3 | Phase 3 current-sense differential inputs | Enable lossless current balance across three phases; disable phase 3 by tying CSP3 to VCC and CSN3 to GND. |
| THRM | Thermal fault comparator input | Accepts resistor-thermistor divider voltage; triggers VRHOT when THRM falls below 30% of VCC (≈1.5V at 5V). |
| IMON | Summed analog current monitor output | Delivers ILOAD × 1.6mS × RIMON; high-impedance in shutdown to avoid loading monitoring circuitry. |
| TIME | Slew-rate control reference | RTIME resistor sets VID transition rate (e.g., 147kΩ = 6.08mV/μs); startup/shutdown slew is fixed at ¼ normal rate. |
| PWM3 / DRSKP | External third-phase gate drive outputs | Drive external driver (e.g., MAX8791); DRSKP enables/disables phase 3 dynamically based on load conditions. |
| FB / FBAC | Main feedback and droop amplifier outputs | FB compares regulated voltage; FBAC provides AC droop signal - short FB to FBAC for matched DC/AC droop. |
Key Features
| Feature | Design Value |
|---|---|
| Transient suppression (MAX17036 only) | Reduces output capacitance requirement by overlapping phase activation during fast load transients. |
| Active voltage positioning | Adjustable gain allows optimal compensation for tantalum, polymer, or ceramic bulk capacitors - minimizing power loss and size. |
| Lossless current balance | Accurate valley current limit and droop amplifier (Gm = 400μS) ensure ±1mV/phase matching across all enabled phases. |
| Integrated boost switches | Eliminates need for external BST diodes; supports high-side FET drive up to 36V bootstrap voltage. |
| Remote sense with GNDS | GNDS input compensates for PCB trace IR drop - maintains ±0.5% regulation accuracy at CPU socket. |
Applications
| IMVP-6.5 Notebook Core Supply | High-Current Voltage-Positioned Converter |

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 |
|---|---|---|---|
| MAX17030GTL+ | Lacks transient suppression (MAX17036-specific) and has identical pinout, package, and IMVP-6.5 compliance. | Suitable for cost-sensitive designs where phase overlap during transients is not required. | Select MAX17030GTL+ when system-level transient testing confirms adequate output capacitance without suppression. |
| ISL6322CRZ | 3-phase IMVP-6.0 controller with 6-bit VID, no integrated BST switches, and different thermal fault logic (THERM vs VRHOT). | Requires external BST diodes and supports older Intel platforms; lacks MAX17036's slew-rate control and IMON accuracy. | Choose ISL6322CRZ only for legacy IMVP-6.0 designs or when sourcing constraints require Renesas-compatible supply chains. |
Compared with MAX17030GTL+, the MAX17036GTL+ adds transient suppression to reduce output capacitance needs; compared with ISL6322CRZ, it offers tighter VOUT accuracy, integrated BST, and IMVP-6.5 compliance - making it the preferred choice for new Intel 45nm/32nm notebook platforms.

FAQ
What is the key functional difference between MAX17036GTL+ and MAX17030GTL+?
The MAX17036GTL+ includes transient suppression - a feature that overlaps phase activation during fast load steps to reduce required output capacitance. The MAX17030GTL+ lacks this capability but shares identical pinout, package, IMVP-6.5 compliance, and ±0.5% VOUT accuracy. Both support 2-/3-phase operation and integrated drivers.
Does MAX17036GTL+ support 3-phase operation out of the box?
Yes, the MAX17036GTL+ supports 3-phase operation natively via its PWM3 and DRSKP outputs, which drive an external third-phase driver like the MAX8791. Phase 3 is disabled by default; enable it by configuring CSP3/CSN3 and asserting DRSKP. Internal drivers handle phases 1 and 2.
What is the purpose of the TIME pin on MAX17036GTL+?
The TIME pin on MAX17036GTL+ sets the slew rate for VID code transitions using an external resistor (RTIME). A 147kΩ resistor yields 6.08mV/μs nominal slew; startup and shutdown use ¼ that rate. This controls voltage ramping during boot, sleep/wake, and mode changes to prevent CPU reset or instability.
How does MAX17036GTL+ implement active voltage positioning?
The MAX17036GTL+ uses its FBAC pin and internal transconductance amplifier (Gm = 400μS) to inject controlled droop proportional to load current. By connecting FBAC to the feedback network, designers adjust gain to match ESR characteristics of tantalum, polymer, or ceramic output capacitors - reducing bulk capacitance and power loss.
Can MAX17036GTL+ be used in desktop or server applications?
The MAX17036GTL+ is qualified for -40°C to +105°C and meets IMVP-6.5 timing requirements intended for mobile CPUs. While electrically capable in desktop/server environments, it lacks VR12/VR12.5 or IMVP-7 compliance - so use in those platforms requires validation against platform-specific power delivery specifications and thermal profiles.
