Product details
Overview
MAX20011GAFOA/VY+T 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 output voltage accuracy and ASIL D compliance for safety-critical ADAS power rails.
For engineers reviewing the MAX20011GAFOA/VY+T datasheet, MAX20011GAFOA/VY+T pinout, MAX20011GAFOA/VY+T application, or MAX20011GAFOA/VY+T equivalent, this device supports I²C-controlled dynamic voltage scaling (6.25mV steps), differential remote sensing, spread-spectrum EMI reduction, and programmable soft-start-key for SoC core rail sequencing and transient response in automotive domain controllers.
Technical Context
The MAX20011GAFOA/VY+T implements a current-mode, forced-PWM control architecture with integrated high- and low-side MOSFETs (RDS(on) optimized for 16A operation), factory-preset output voltage, and dual-frequency capability (2.2MHz or 1.1MHz). Its internal block includes redundant voltage references, BIST diagnostics, and PEC-protected I²C for functional safety.
It features differential remote sense inputs (RS+/RS−), open-drain RESET with programmable timeout (3.7ms default), and SYNC pin configurable as input (for external clock synchronization) or output (to drive other converters), enabling precise timing coordination across multi-rail automotive power systems.

Pinout & Package
MAX20011GAFOA/VY+T is housed in a 3.5mm × 4mm, 17-pin side-wettable FC2QFN package (package code F173A4FY+2) with exposed pad (EP) internally connected to PV, supporting automated optical inspection (AOI) and enhanced thermal performance via PCB copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Active-high enable | Initiates soft-start on rising edge; triggers controlled shutdown on falling edge |
| BST | Bootstrap supply | Provides gate drive voltage for high-side MOSFET; requires 0.1μF ceramic capacitor to LX |
| PV (pins 3, 9, 16, 17) | Main power input | Dual-path 5V rail input; requires ≥2×10μF ceramic capacitors per PV group to PGND |
| PGND (pins 4, 5, 7, 8, 11, 12) | Power ground | Low-impedance return for high di/dt switching current; must be solidly tied to thermal pad |
| LX (pin 6) | Switch node | Connects to inductor switch node; high dv/dt path requiring minimized loop area and tight layout |

FAQ
What is the maximum output current capability of the MAX20011GAFOA/VY+T?
The MAX20011GAFOA/VY+T delivers up to 16A peak output current, verified across the full −40°C to +125°C automotive temperature range. This rating is achieved using its integrated low-RDS(on) power switches and optimized thermal design in the 3.5mm × 4mm FC2QFN package. The device maintains regulation and protection functionality even under sustained 16A loads with proper PCB thermal management.
Does the MAX20011GAFOA/VY+T support dynamic voltage scaling (DVS)?
Yes, the MAX20011GAFOA/VY+T supports I²C-controlled dynamic voltage scaling with 6.25mV resolution across 0.5V–1.275V. Voltage changes are executed via VID[7:0] register writes, and slew rate is independently programmable through the SLEW register-enabling precise control of transition speed for SoC DVFS and margining without causing system instability.
How does the MAX20011GAFOA/VY+T meet ASIL D requirements?
The MAX20011GAFOA/VY+T meets ASIL D through redundant internal voltage references, built-in self-test (BIST) diagnostics, PEC-protected I²C communication, and ±1% accurate overvoltage/undervoltage detection. These features are documented in its safety manual and certified per ISO 26262, enabling direct integration into safety goals for ADAS domain controllers without additional external monitoring circuitry.
What package type and thermal characteristics does the MAX20011GAFOA/VY+T use?
The MAX20011GAFOA/VY+T uses a 3.5mm × 4mm, 17-pin side-wettable FC2QFN package (F173A4FY+2) with exposed thermal pad connected internally to PV. On a 4-layer board, its junction-to-ambient thermal resistance (θJA) is 35.3°C/W, and junction-to-case (θJC) is 7.9°C/W-enabling efficient heat transfer to PCB copper pours for sustained 16A operation in automotive under-hood environments.
Can the MAX20011GAFOA/VY+T be synchronized to an external clock?
Yes, the MAX20011GAFOA/VY+T's SYNC pin is factory-configurable as an input to accept external clock signals in the 1.8–2.6MHz range (when CONFIG.FSW = 0) or 0.9–1.3MHz (when CONFIG.FSW = 1). This allows precise timing alignment across multiple power rails in domain controllers, eliminating beat frequencies and reducing system-level EMI peaks.
