Product details
Overview
MAX20410AFOA/VY+ 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 from a 3.0V–36V input. It features 10μA quiescent current in skip mode, 2.1MHz/400kHz selectable switching frequency, and AEC-Q100 qualification for use in ADAS power rails and infotainment domain controllers.
For engineers reviewing the MAX20410AFOA/VY+ datasheet, MAX20410AFOA/VY+ pinout, MAX20410AFOA/VY+ application, or MAX20410AFOA/VY+ equivalent, key selection criteria include dual-phase scalability to 20A, ±1% output voltage accuracy (E-version), windowed PGOOD, and 99% dropout duty cycle - all critical for automotive 12V/24V system designs requiring ultra-low IQ and EMI robustness.
Technical Context
The MAX20410AFOA/VY+ implements average current-mode control with 34ns minimum on-time, enabling stable operation across wide VIN/VOUT ratios (e.g., 24V→3.3V) without pulse-skipping instability. Its dual-phase capability uses VEA pin coupling and SYNCOUT-to-SYNC interconnection to achieve dynamic current sharing and precise 180° phase alignment between controller and target ICs.
It integrates a 1.8V BIAS LDO, supports programmable EN threshold (0.825V–0.975V), and delivers fixed or adjustable outputs (0.8V–10V at 2.1MHz; 0.8V–6V at 2.1MHz for non-E variants). The FC2QFN package enables symmetric SUP/PGND routing to minimize high-di/dt loop area and reduce radiated EMI.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.0V to 36V - supports full automotive battery range including cold-crank (3V) and load-dump (42V transient tolerance) |
| Max Output Current | 10A - verified continuous DC output with thermal derating per θJA = 27°C/W on 4-layer EV kit |
| Quiescent Current | 10μA in skip mode - enables always-on systems (e.g., telematics wake-up) without battery drain |
| Switching Frequency | 2.1MHz or 400kHz - enables <1μH inductors and <22μF ceramic output caps; avoids AM band interference |
| Output Voltage Accuracy | ±1% (MAX20410E variant) - ensures reliable SoC core rail regulation under line/load/temp variation |
| Duty Cycle Max | 99% - sustains regulation down to VIN = VOUT + 0.3V, critical for 12V→5V/3.3V automotive supplies |
| PGOOD Window | 102.75%–107.25% (rising), 101.75%–106.25% (falling) - provides precise fault detection for safety-critical loads |
Pinout & Package
MAX20410AFOA/VY+ uses a thermally enhanced 3.5mm × 3.75mm, 17-pin FC2QFN package with exposed thermal pad (pin 17). Symmetric SUP and PGND pin placement minimizes high-current loop inductance and improves EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 EN | Enable Input | High-voltage compatible (3V–36V); 0.9V typical threshold enables direct connection to automotive microcontroller GPIO |
| 2 BST | Bootstrap Supply | Drives high-side gate; requires 0.1μF ceramic cap to LX for reliable 10A switching |
| 3, 9 SUP | IC Power Input | Dual pins internally connected; bypassed with 0.1μF + 4.7μF ceramics to PGND for low-impedance VIN path |
| 4, 5, 7 PGND | Power Ground | Three dedicated PGND pins reduce ground bounce and improve current-sense accuracy at 10A |
| 6 LX | Switch Node | Connects to buck inductor; high-impedance when disabled; layout must minimize loop area for EMI control |
| 10 GND | Analog Ground | Separate from PGND; connects to PCB ground plane at single point to avoid noise coupling into FB/VEA |
| 11 BIAS | LDO Output | 1.8V internal supply; requires ≥2.2μF ceramic cap to GND; powers internal logic and enables VOUT > 2.5V self-bias |
| 12 FB | Feedback Input | 0.8V reference; connects to resistor divider for adjustable output or to BIAS for fixed output (e.g., 3.3V/5V) |
| 13 OUT | Output Sense | Used only when FB tied to BIAS; enables accurate remote sensing of regulated output voltage |
| 14 VEA | Error Amplifier Output | Shared between controller/target in dual-phase mode; enables matched current sharing and transient response |
| 15 PGOOD | Power-Good Indicator | Open-drain; asserts low during soft-start or if VOUT falls outside window; requires external pull-up to BIAS or VOUT |
| 16 SYNC | Synchronization Input | Selects FPWM (high), skip mode (low), or external clock sync; accepts 1.7–2.6MHz (2.1MHz mode) or 360–600kHz (400kHz mode) |
| 17 SYNCOUT | Phase-Shifted Clock Output | 180° out-of-phase signal; used to configure target IC in dual-phase; connect to BIAS to disable in single-phase |
Key Features
| Feature | Design Value |
|---|---|

| Windowed PGOOD | Asymmetric rising/falling thresholds (102.75%–107.25% / 101.75%–106.25%) enable precise overvoltage and undervoltage fault detection for ASIL-B compliance |
| Spread-spectrum EMI reduction | ±3% frequency modulation centered at fSW reduces peak radiated emissions by >10dB without external filters |
| Ultra-low dropout operation | 99% duty cycle allows regulation with <0.3V headroom - essential for 12V systems powering 5V/3.3V rails during cold-crank |

FAQ
What is the maximum continuous output current supported by the MAX20410AFOA/VY+?
The MAX20410AFOA/VY+ delivers up to 10A continuous DC output current under recommended thermal conditions (θJA = 27°C/W on 4-layer EV kit). This rating is validated across -40°C to +125°C ambient and includes derating above +70°C at 37mW/°C. Peak current limit is 14A, ensuring robust overload protection.
Does the MAX20410AFOA/VY+ support dual-phase operation, and how is it configured?
Yes, the MAX20410AFOA/VY+ supports dual-phase operation up to 20A. One IC is configured as controller (SYNCOUT left open), the other as target (SYNCOUT tied to BIAS). VEA pins are connected between both ICs, and SYNC of the target is driven by SYNCOUT of the controller to enforce 180° phase shift and dynamic current sharing.
What is the purpose of the windowed PGOOD feature in the MAX20410AFOA/VY+?
The windowed PGOOD in the MAX20410AFOA/VY+ provides asymmetric overvoltage and undervoltage detection: rising threshold is 102.75%–107.25% of nominal VOUT, falling threshold is 101.75%–106.25%. This enables precise fault isolation in safety-critical automotive systems, distinguishing between transient dips and sustained faults without false triggers.
Can the MAX20410AFOA/VY+ operate with input voltages below 3.0V, such as during cold-crank events?
No - the absolute minimum input voltage for the MAX20410AFOA/VY+ is 3.0V per datasheet specifications. However, it supports 99% duty cycle operation, allowing regulation down to VIN = VOUT + 0.3V. For cold-crank scenarios where VIN may dip to ~6V (12V system) or ~12V (24V system), this ensures uninterrupted 5V/3.3V output without dropout.
How does the spread-spectrum feature reduce EMI in the MAX20410AFOA/VY+?
The MAX20410AFOA/VY+ reduces peak radiated EMI by modulating its switching frequency ±3% around the nominal value (2.1MHz or 400kHz) using a triangular waveform. At 2.1MHz, this creates a 4.5kHz modulation that spreads energy across a 126kHz bandwidth, lowering peak emissions by >10dB - eliminating need for ferrite beads or shielding in many automotive layouts.
