Product details
Overview
MAX20410AFOE/VY+T from Analog Devices is an automotive-grade, fully integrated synchronous buck converter with internal high-side and low-side MOSFETs, delivering up to 10A output current across 3.0V–36V input range, featuring 10μA quiescent current in skip mode, 2.1MHz/400kHz selectable switching frequency, and AEC-Q100 qualification for ADAS and infotainment power rails.
For engineers reviewing the MAX20410AFOE/VY+T datasheet, MAX20410AFOE/VY+T pinout, MAX20410AFOE/VY+T application, or MAX20410AFOE/VY+T equivalent, this page delivers verified technical context, dual-phase configuration guidance, PGOOD windowing behavior, thermal shutdown thresholds, and FC2QFN package-level EMI design implications - all specific to the MAX20410AFOE/VY+T variant.
Technical Context
The MAX20410AFOE/VY+T implements average current-mode control with 34ns minimum on-time, enabling stable operation under large VIN/VOUT step-down ratios without pulse-skipping artifacts. It supports three SYNC-driven operating modes: forced-PWM (FPWM), skip mode (10μA IQ), and external clock synchronization - with spread-spectrum modulation (±3% fSW) factory-enabled to reduce radiated EMI.
Dual-phase capability is implemented via master-slave configuration using VEA coupling and 180° out-of-phase SYNCOUT, enabling dynamic current sharing up to 20A. The device integrates a 1.8V BIAS LDO, windowed PGOOD (102.75%–107.25% rising / 101.75%–106.25% falling), and accurate EN threshold (0.825V–0.975V) optimized for automotive battery monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 10A max continuous - enables single-chip 5V/10A rail for radar modules or domain controllers. |
| Input Voltage Range | 3.0V to 36V - supports cold-crank (4.5V) and load-dump (42V transient) conditions per ISO 7637-2. |
| Quiescent Current | 10μA in skip mode - sustains >1-year battery standby in always-on ADAS camera ECUs. |
| Switching Frequency | 2.1MHz or 400kHz fixed - 2.1MHz allows <1μH inductors and avoids AM band interference. |
| Output Voltage Accuracy | ±1% over -40°C to +125°C - ensures reliable DDR memory or SoC core voltage regulation. |
| PGOOD Window | 102.75%–107.25% (rising), 101.75%–106.25% (falling) - prevents false asserts during transient load steps. |
| Thermal Shutdown | 175°C with 20°C hysteresis - protects against sustained overload in sealed junction-box environments. |
Pinout & Package
MAX20410AFOE/VY+T uses a thermally enhanced 3.5mm × 3.75mm, 17-pin FC2QFN package with exposed thermal pad (θJCb = 7.7°C/W on 4-layer JEDEC board). Symmetric SUP/PGND pin placement minimizes high-current loop area for superior EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, EN | Enable Input | High-voltage compatible (3V–36V); 0.825V–0.975V threshold enables direct connection to automotive wake-up lines. |
| 2, BST | Bootstrap Supply | Requires 0.1μF ceramic capacitor to LX; enables high-side gate drive above VIN. |
| 3, 9, SUP | IC Power Input | Dual pins internally connected; bypass with 0.1μF + 4.7μF ceramics near IC for transient immunity. |
| 4, 5, 7, 8, PGND | Power Ground | Five dedicated PGND pins reduce ground impedance and improve current sharing in dual-phase layouts. |
| 6, LX | Switch Node | Connects to buck inductor; high-impedance when disabled; requires tight layout to minimize EMI. |
| 10, GND | Analog Ground | Separate from PGND; connect only at single point to avoid noise coupling into feedback path. |
| 11, BIAS | LDO Output | 1.8V regulated supply for internal circuitry; requires ≥2.2μF ceramic to GND for stability. |
| 12, FB | Feedback Input | 0.8V reference; connects to resistor divider for adjustable outputs (0.8V–10V) or to BIAS for fixed outputs. |
| 13, OUT | Output Sense | Used only when FB tied to BIAS; enables remote sensing for improved load regulation. |
| 14, VEA | Error Amplifier Output | Connect to slave IC's VEA in dual-phase mode for matched current sharing; open in single-phase. |
| 15, PGOOD | Open-Drain Status | Windowed indicator (101.75%–107.25%) - pull up to BIAS or 3.3V; asserts low during soft-start. |
| 16, SYNC | Mode Control Input | Low = skip mode; high = FPWM; external clock = sync mode - no internal filtering of external modulation. |
| 17, SYNCOUT | Phase Clock Output | 180° out-of-phase signal; tie to BIAS to configure as slave in dual-phase; leave open otherwise. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-phase scalability | Two MAX20410AFOE/VY+T ICs support 20A output with dynamic current sharing and 180° phase shift - eliminates need for external current-sharing ICs. |
| Windowed PGOOD | Asymmetric rising/falling thresholds (102.75%/101.75% to 107.25%/106.25%) prevent chatter during fast load transients in ADAS vision processors. |
| Ultra-low IQ skip mode | 10μA quiescent current enables >1-year battery hold-up for always-on vehicle telematics modules without compromising startup time. |
| Dropout operation | 99% duty cycle allows regulation down to VOUT = 0.99 × VIN - critical for 12V-to-5V conversion during cold-crank (5.5V min). |
| Spread-spectrum EMI reduction | ±3% triangular dither at 4.5kHz (2.1MHz) reduces peak radiated emissions by >10dB without affecting loop stability or transient response. |
| AEC-Q100 Grade-1 | Qualified from -40°C to +125°C ambient - validated for engine bay, head unit, and radar ECU mounting locations. |

FAQ
What is the maximum output current rating of the MAX20410AFOE/VY+T?
The MAX20410AFOE/VY+T is rated for 10A continuous output current under recommended operating conditions (TA ≤ +125°C, proper PCB thermal design). This rating assumes use of the 17-pin FC2QFN package with adequate copper pour and thermal vias. Derating applies above +70°C ambient per θJA = 38.6°C/W. The device achieves this with integrated 25mΩ high-side and 12mΩ low-side MOSFETs.
Does the MAX20410AFOE/VY+T support dual-phase operation, and how is it configured?
Yes, the MAX20410AFOE/VY+T supports dual-phase operation up to 20A total output. Configuration requires two identical MAX20410AFOE/VY+T ICs: one as controller (SYNCOUT left open), one as target (SYNCOUT tied to BIAS). VEA pins are connected between ICs, and SYNC of the target is driven by SYNCOUT of the controller. This enables 180° phase shift and dynamic current sharing without external components.
What is the purpose of the windowed PGOOD feature in the MAX20410AFOE/VY+T?
The MAX20410AFOE/VY+T implements a windowed PGOOD with asymmetric thresholds: rising edge at 102.75%–107.25% and falling edge at 101.75%–106.25% of nominal VOUT. This prevents false assertions during fast load transients - such as those seen in ADAS vision processors - while maintaining precise fault detection. Standard PGOOD versions (e.g., MAX20410AFOE/VY+) use narrower 92%–96% windows.
How does the MAX20410AFOE/VY+T achieve ultra-low quiescent current, and what is its value?
The MAX20410AFOE/VY+T achieves 10μA quiescent current in skip mode by disabling switching activity during light loads and powering internal circuitry from the 1.8V BIAS LDO. This value is measured at no load, 14V input, and +25°C ambient. In shutdown (EN low), IQ drops further to 4μA. The low IQ enables multi-year battery standby in always-on automotive modules like telematics control units.
Is the MAX20410AFOE/VY+T qualified for automotive applications, and what standards does it meet?
Yes, the MAX20410AFOE/VY+T is AEC-Q100 Grade-1 qualified (-40°C to +125°C ambient), supporting automotive deployment in engine bay, cabin, and ADAS zones. It withstands 42V load dump per ISO 7637-2, meets CISPR 25 Class 5 EMI requirements when used with spread-spectrum and proper layout, and includes overtemperature shutdown (175°C) and hiccup-mode short-circuit protection.
