Product details
Overview
MAX8796GTJ+ from Maxim Integrated is a 1-phase Quick-PWM™ step-down controller for Intel IMVP-6 and GMCH core power supplies, supporting ±0.5% VOUT accuracy over line/load/temperature, 7-bit IMVP-6 DAC, and active voltage positioning. It operates from 2V to 26V input and drives synchronous rectifier FETs in notebook CPU/GPU core supply applications.
For engineers reviewing the MAX8796GTJ+ datasheet, MAX8796GTJ+ pinout, MAX8796GTJ+ application, or MAX8796GTJ+ equivalent, key selection criteria include IMVP-6/GMCH compliance, TQFN-32 package compatibility, output-voltage slew-rate control, thermistor-based thermal protection, and integrated power monitoring capability.
Technical Context
The MAX8796GTJ+ implements dual-specification control logic supporting both Intel IMVP-6 CPU core and GMCH graphics core requirements, using a Quick-PWM architecture with instantaneous load-step response. It integrates a 7-bit VID DAC for CPU core voltage programming and a separate 5-bit DAC for GMCH voltage scaling.
Active voltage positioning is implemented via adjustable gain droop control, enabling optimal compensation for tantalum, polymer, or ceramic bulk capacitors. The device supports single-stage battery-to-core conversion (2–4 Li+ cells) or two-stage +5V system rail conversion, with programmable switching frequency up to 600kHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar IMVP-6/GMCH controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX17401 | Same 1-phase Quick-PWM architecture, identical 7-bit IMVP-6 + 5-bit GMCH DAC, TQFN-32 package. | No output overvoltage protection; lacks PWRMON output. | Select MAX17401 only if OVP and power monitoring are not required. |
| MAX8797GTI+ | 28-pin TQFN package; supports GMCH only (no IMVP-6 CPU core support); no 7-bit DAC. | Designed exclusively for graphics core applications; incompatible with CPU core VID protocols. | Choose MAX8797GTI+ only for GMCH-only systems where CPU regulation is handled separately. |
Compared with MAX17401 and MAX8797GTI+, the MAX8796GTJ+ uniquely combines full IMVP-6 CPU + GMCH graphics support, output overvoltage protection, and analog power monitoring in a single TQFN-32 device-making it the only option for dual-domain core power in space-constrained UMPC designs.

FAQ
What is the primary function of the MAX8796GTJ+ in Intel-based systems?
The MAX8796GTJ+ serves as a dual-specification 1-phase Quick-PWM controller that regulates both Intel IMVP-6 CPU core voltage and GMCH graphics core voltage. It implements active voltage positioning, VID-programmable outputs, and real-time power monitoring-enabling high-efficiency, thermally optimized core power delivery in UMPCs and notebooks. The MAX8796GTJ+ is essential for meeting Intel's stringent transient response and accuracy requirements.
Does the MAX8796GTJ+ support both battery-input and +5V system-rail input configurations?
Yes, the MAX8796GTJ+ supports both configurations: it can directly step down 2–4 Li+ cell battery voltage (up to ~16.8V) or derive core voltage from a +5V system rail. Its 2V–26V input range and programmable switching frequency allow designers to optimize for either peak efficiency (battery direct) or minimal footprint (+5V two-stage). This flexibility is explicitly confirmed in the MAX8796GTJ+ datasheet and application notes.
What package type and thermal characteristics does the MAX8796GTJ+ use?
The MAX8796GTJ+ uses a 32-pin TQFN package (5mm × 5mm, 0.5mm pitch) with exposed thermal pad, per outline drawing 21-0140. It is rated for operation from −40°C to +105°C ambient, with thermal resistance θJA of 36°C/W (typical) and θJC of 5.5°C/W (typical). The package supports reflow soldering and meets RoHS/lead-free requirements.
How does the MAX8796GTJ+ implement active voltage positioning, and what design benefit does it provide?
The MAX8796GTJ+ implements active voltage positioning through adjustable gain droop control, which intentionally lowers output voltage under increasing load current. This reduces total power loss (I²R + V×I) and allows smaller bulk output capacitors-especially beneficial with polymer or ceramic types. The feature is programmable via external resistors and is validated for ≤1% droop error across temperature, directly improving thermal performance in fanless designs.
Is the MAX8796GTJ+ pin-compatible with the MAX8797GTI+ or MAX17401?
No, the MAX8796GTJ+ is not pin-compatible with the MAX8797GTI+ due to differing pin counts (32 vs. 28) and distinct pin functions-MAX8797GTI+ lacks IMVP-6 VID pins and PWRMON. It is pin-compatible with the MAX17401 (same TQFN-32 package and pinout), but MAX17401 omits output overvoltage protection and the PWRMON output. Board reuse requires verification of these functional differences.
