Product details
Overview
MAX17082GTL+ from Maxim Integrated is a dual-phase, Quick-PWM™ step-down VID power-supply controller for IMVP-6.5 CPU core supplies, delivering ±0.5% output voltage accuracy over line/load/temperature, 7-bit 0–1.50V VID control, and programmable 200kHz–800kHz switching frequency. It supports active voltage positioning, true differential current sensing, and integrated boost switches for notebook CPU power delivery.
For engineers reviewing the MAX17082GTL+ datasheet, MAX17082GTL+ pinout, MAX17082GTL+ application, or MAX17082GTL+ equivalent, key selection criteria include IMVP-6.5 compliance, dual-phase current balance (±1.0mV offset), VRHOT thermal-fault signaling, IMON analog current monitor output, and 40-pin TQFN package with exposed ground pad.
Technical Context
The MAX17082GTL+ implements interleaved dual-phase Quick-PWM control with out-of-phase operation to reduce input/output ripple and enable transient phase overlap-cutting required bulk capacitance. Its droop amplifier (Gm = 585–610μS) and current-balance amplifier (Gm = 200μS, ±1.25mV offset) ensure precise per-phase current sharing across load steps.
It integrates slew-rate control via RTIME resistor for soft-start/shutdown, supports DPRSLPVR-driven dynamic phase selection, and provides dedicated fault outputs: PWRGD (3–10ms startup delay), PHASEGD (32-pulse blanking on phase enable), and VRHOT (30% VCC trip threshold, 10μs propagation delay).

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-phase CPU core controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX17021GTL+ | IMVP-6+ compliant (Montevina), higher 1.75–1.85V OVP threshold, DPRSTP instead of SLOW pin | Targeted for older Intel platforms; lacks IMON output and uses different VID timing | Select MAX17021GTL+ only for legacy Montevina-based designs requiring IMVP-6+ timing and no current monitoring |
| MAX17482GTL+ | Identical IMVP-6.5 spec, same pinout and electrical specs - differs only in factory programming of internal registers | No functional difference in circuit implementation or system integration | MAX17482GTL+ is a drop-in alternative with identical design-in path; verify register defaults match firmware expectations |
Compared with MAX17021GTL+, MAX17082GTL+ adds IMON current telemetry and uses SLOW instead of DPRSTP for slow-mode entry; versus MAX17482GTL+, it shares identical hardware but may differ in default register configuration for specific OEM implementations.

FAQ
What is the primary function of the MAX17082GTL+ in a CPU power delivery system?
The MAX17082GTL+ serves as a dual-phase, Quick-PWM™ step-down controller that regulates the CPU core voltage using Intel IMVP-6.5 VID protocol. It manages two synchronous buck phases with active voltage positioning, differential current sensing, and integrated gate drivers - enabling high efficiency, fast transient response, and thermal fault protection in notebook and desktop platforms. The MAX17082GTL+ directly interfaces with the CPU's VID lines and delivers tightly regulated Vcore across dynamic load conditions.
Does the MAX17082GTL+ support current monitoring, and how is it implemented?
Yes, the MAX17082GTL+ includes an integrated current monitor (IMON) output that provides an analog current proportional to total CPU power consumption. With a nominal full-load output of 96μA and transconductance of 2.2–2.6mS, IMON converts summed phase currents into a single analog signal referenced to VCC. This feature is exclusive to MAX17082GTL+ and MAX17482GTL+ (not present in MAX17021GTL+), and is used for system-level power telemetry and thermal management. The MAX17082GTL+ IMON output is specified across -40°C to +105°C.
How does the MAX17082GTL+ handle thermal protection, and what is the VRHOT threshold?
The MAX17082GTL+ implements thermal protection via the VRHOT output, which asserts low when the THRM pin voltage falls below 30% of VCC (28–32% guaranteed). This threshold scales with VCC, eliminating need for external voltage dividers. Propagation delay is 10μs, and the output features 2–10Ω on-resistance in active state. VRHOT connects directly to CPU thermal throttle inputs and works in conjunction with the 160°C junction thermal shutdown. The MAX17082GTL+ uses this architecture to provide scalable, supply-referenced thermal fault signaling without external components.
What package type and thermal characteristics does the MAX17082GTL+ use?
The MAX17082GTL+ is packaged in a 5mm × 5mm, 40-pin thin QFN with exposed thermal pad (EP), rated for -40°C to +105°C operating temperature. The exposed pad must be soldered to a solid GND plane for optimal thermal performance; the package dissipates up to 1778mW at +70°C with 22.2mW/°C derating above that. Thermal resistance θJA is optimized for compact notebook PCB layouts, and the EP connection significantly lowers junction-to-board thermal impedance - critical for sustained high-current operation in space-constrained systems. This package is shared across MAX17021GTL+, MAX17082GTL+, and MAX17482GTL+.
Can the MAX17082GTL+ be used in single-phase configurations, and how is phase count selected?
The MAX17082GTL+ is designed for dual-phase operation but supports single-phase mode via DPRSLPVR pin control: pulling DPRSLPVR low disables Phase 2, leaving only Phase 1 active. This dynamic phase selection optimizes light-load efficiency without changing hardware. The device retains full functionality - including IMON, VRHOT, and PWRGD - in single-phase mode. Unlike fixed single-phase controllers, the MAX17082GTL+ maintains its 2-phase current balance circuitry and can re-enable Phase 2 instantly upon load increase. This flexibility makes the MAX17082GTL+ suitable for both dual- and adaptive single-phase CPU VR designs.
