Product details
Overview
MAX20011GAFOA/VY+ from Analog Devices is an automotive-grade, synchronous step-down DC-DC converter delivering up to 16A peak output current, operating from 3.0V–5.5V input to 0.5V–1.275V output with ±1.5% full-range voltage accuracy and ASIL D compliance for ADAS SoC core power regulation.
For engineers reviewing the MAX20011GAFOA/VY+ datasheet, MAX20011GAFOA/VY+ pinout, MAX20011GAFOA/VY+ application, or MAX20011GAFOA/VY+ equivalent, this page delivers verified technical context, I²C-programmable DVS with 6.25mV steps, 2.2MHz fixed-frequency PWM operation, differential remote sensing, and factory-preset voltage configuration specific to the MAX20011G variant.
Technical Context
The MAX20011GAFOA/VY+ implements current-mode control with forced PWM operation, enabling stable regulation under fast load transients typical in automotive SoC power domains. Its integrated high- and low-side MOSFETs feature low RDS(on), supporting >92% efficiency at 12A/1V out (5V in) while minimizing thermal stress in compact layouts.
ASIL D compliance is achieved via redundant internal voltage references, built-in self-test (BIST) diagnostics, packet error checking (PEC) on I²C, and programmable overvoltage/undervoltage detection with ±1% accuracy - all validated across −40°C to +125°C ambient operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 16A peak - supports high-power automotive SoC cores without external current boosting. |
| Input Voltage Range | 3.0V to 5.5V - compatible with standard automotive 3.3V/5V rails and battery-supervised systems. |
| Output Voltage Range | 0.5V to 1.275V in 6.25mV steps - enables precise dynamic voltage scaling for processor DVFS. |
| Switching Frequency | 2.2MHz (fixed) or 1.1MHz - allows full-ceramic filtering and reduces EMI filter size. |
| Voltage Accuracy | ±1.5% over line/load/temp - ensures reliable SoC VDD margining across automotive temperature extremes. |
| Operating Temp | −40°C to +125°C (Grade 1) - qualified for under-hood and ADAS domain controller environments. |
| I²C Interface | Up to 1MHz clock - supports real-time VID updates and telemetry readback in safety-critical systems. |
Pinout & Package
MAX20011GAFOA/VY+ uses a 3.5mm × 4mm, 17-pin side-wettable FC2QFN package (package code F173A4FY+2) with exposed pad (EP) internally connected to PV for enhanced thermal performance in automotive PCB stacks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 1) | Active-high enable | Starts soft-start sequence on rising edge; initiates controlled shutdown on falling edge. |
| BST (Pin 2) | Bootstrap supply | Drives high-side gate; requires 0.1μF ceramic capacitor between BST and LX for proper bootstrap charging. |
| PV (Pins 3, 9, 16, 17) | Main power input | Supplies internal circuitry and high-side switch; must be decoupled with ≥4×10μF ceramic capacitors to PGND. |
| PGND (Pins 4, 5, 7, 8, 11, 12) | Power ground return | Low-impedance path for high di/dt switching currents; connects directly to LX and PV decoupling caps. |
| LX (Pin 6) | Switch node | Connects to inductor; carries full switching waveform; layout must minimize loop area to reduce EMI. |
| RS+, RS− (Pins 10, 11) | Differential remote sense | Enables accurate regulation at load point by rejecting PCB IR drop; RS+ trace resistance ≤2Ω required. |
| RESET (Pin 13) | Open-drain fault indicator | Asserts low when VOUT deviates beyond programmed OV/UV window; requires external pull-up for logic-level signaling. |
| SCL/SDA (Pins 16, 17) | I²C interface | Supports dynamic voltage adjustment, register readback, and diagnostic status reporting per AEC-Q100 requirements. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL D compliance | Redundant reference, BIST, PEC on I²C, and ±1% OV/UV thresholds meet ISO 26262 functional safety requirements. |
| Differential remote sensing | Compensates for up to 100mV PCB trace IR drop, maintaining ±1.5% regulation accuracy at the SoC VDD pin. |
| Programmable soft-start | Slew rate configured via SLEW register to limit inrush current during cold start or reset sequences. |
| Spread-spectrum modulation | ±3% frequency dithering reduces peak radiated emissions without compromising transient response. |
| Thermal protection | 165°C shutdown with 15°C hysteresis prevents latch-up during sustained overload or poor heatsinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current automotive buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4436AGL-AEC1-P | 16A peak, 2.2MHz, but lacks ASIL D features (no BIST, no PEC, no redundant reference). | Targeted at non-safety-critical infotainment subsystems; not certified for ASIL B/D domains. | Select only if functional safety compliance is not required and cost sensitivity outweighs diagnostic coverage needs. |
| TPS62933EVM-012 | 12A peak, 2.2MHz, supports I²C DVS and remote sensing, but rated only to +105°C ambient. | Valid for cabin-zone applications (e.g., HUD, rear-seat displays), not engine-bay or radar modules. | Choose when thermal envelope permits lower junction temperature and ASIL D is not mandated. |

FAQ
What is the maximum output current rating of the MAX20011GAFOA/VY+?
The MAX20011GAFOA/VY+ is the MAX20011G variant and is rated for up to 16A peak output current. This rating is validated across the full −40°C to +125°C operating temperature range and supports continuous 12A loads with appropriate thermal design. The device achieves this using integrated low-RDS(on) MOSFETs and a thermally optimized FC2QFN package.
Does the MAX20011GAFOA/VY+ support dynamic voltage scaling (DVS)?
Yes, the MAX20011GAFOA/VY+ supports I²C-controlled dynamic voltage scaling with 6.25mV resolution across 0.5V–1.275V. DVS slew rate is programmable via the SLEW register, and OV/UV comparators are automatically masked during transitions to prevent false RESET assertions - a critical feature for automotive SoC power sequencing.
What safety certifications apply to the MAX20011GAFOA/VY+?
The MAX20011GAFOA/VY+ is ASIL D compliant per ISO 26262, with redundant voltage references, built-in self-test (BIST) diagnostics, packet error checking (PEC) on I²C, and programmable OV/UV detection with ±1% accuracy. It is also AEC-Q100 Grade 1 qualified (−40°C to +125°C ambient) and supports functional safety analysis per ISO 26262 Part 5.
How does the MAX20011GAFOA/VY+ implement remote voltage sensing?
The MAX20011GAFOA/VY+ uses dedicated RS+ and RS− pins for differential remote sensing, referenced to the load's actual VDD and GND points. This compensates for PCB trace IR drop up to 100mV, ensuring ±1.5% regulation accuracy at the SoC pin. Design requires RS+ trace resistance ≤2Ω and matched routing to maintain common-mode rejection.
What is the purpose of the SYNC pin on the MAX20011GAFOA/VY+?
The SYNC pin on the MAX20011GAFOA/VY+ is a factory-programmable I/O that can accept an external clock (1.8–2.6MHz for 2.2MHz mode; 0.9–1.3MHz for 1.1MHz mode) to synchronize switching across multiple regulators, or output the internal PWM frequency to coordinate timing in multi-rail systems - essential for EMI reduction in dense ADAS PCB layouts.
