Product details
Overview
The MAX20010CATPQ/V+ from Analog Devices is a fully integrated, AEC-Q100 qualified synchronous step-down DC-DC converter delivering up to 6A output current with ±2% output voltage accuracy over load, line, and temperature. It operates from 3.0V–5.5V input and supports programmable output voltages from 0.5V to 1.5875V in 10mV or 12.5mV steps via I²C, and features 2.2MHz fixed-frequency PWM operation with spread-spectrum modulation for automotive point-of-load regulation.
For engineers reviewing the MAX20010CATPQ/V+ datasheet, MAX20010CATPQ/V+ pinout, MAX20010CATPQ/V+ application, or MAX20010CATPQ/V+ equivalent, key selection considerations include its 20-pin TQFN-EP (4mm × 4mm) package, differential remote sensing capability, PGOOD output with 120μs delay, I²C-controlled dynamic voltage scaling (DVS), and robust automotive-grade protections including overcurrent, overtemperature, and short-circuit shutdown.
Technical Context
This IC implements a current-mode, synchronous buck architecture with integrated high-side (31mΩ typ) and low-side (18mΩ typ) MOSFETs, enabling high efficiency across 0–6A loads. Its 2.2MHz switching frequency supports all-ceramic output filtering and minimizes solution footprint while maintaining excellent transient response-especially in MAX20010D/E variants, though the MAX20010C variant retains full 6A capability and ±2% accuracy at 0.8–1.5875V outputs.
The device integrates a 7-bit DAC for I²C voltage programming, configurable soft-start/slew rates (5.5–44 mV/μs), programmable forced-PWM or skip-mode operation via SYNC pin, and differential remote sense inputs (RS+/RS−) for precise load-point regulation. Thermal shutdown activates at 165°C with 15°C hysteresis, and junction-to-case thermal resistance is 2°C/W on a four-layer board.

Pinout & Package
MAX20010CATPQ/V+ uses a 20-pin TQFN-EP package (4mm × 4mm, 0.5mm pitch) with exposed thermal pad (EP) connected to PGND. The layout supports high-current paths via multiple LX (pins 1–4), PV (pins 18–20), and PGND (pins 5–7) terminals, minimizing parasitic inductance and thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX (1–4) | Switch node connection | High-current path to inductor; all pins must be shorted externally for optimal EMI and thermal performance. |
| PGND (5–7) | Power ground return | Low-impedance return for high-side/low-side FETs and output capacitor; separate from analog ground (GND). |
| SDA / SCL (8, 9) | I²C bidirectional data/clock | Supports 3.4MHz operation; requires ≥500Ω pull-up resistors; immune to bus noise via internal spike suppression. |
| RS+ / RS− (10, 11) | Differential remote sense inputs | Compensates for PCB IR drop; enables <±5mV regulation error at load point when properly routed. |
| PG (12) | Open-drain power-good output | Asserts low for 120μs after VOUT enters regulation window; requires external pull-up for logic-level signaling. |
| EN (13) | Active-high enable | Triggers soft-start on rising edge; initiates controlled 5.5mV/μs soft-shutdown when pulled low. |
| SYNC (14) | Frequency synchronization I/O | Configurable as input (1.8–2.6MHz external clock) or output (2.2MHz PWM); enables multi-rail phase alignment. |
| GND (15) | Analog ground reference | Separate from PGND to minimize noise coupling into feedback and control circuits. |
| AV (16) | Analog supply input | Filtered via 100Ω resistor + 1μF ceramic cap to GND; powers internal reference and error amplifier. |
| ADDR (17) | I²C address select | Configures LSB of 7-bit slave address (0x38–0x3F); allows up to 8 devices on same I²C bus. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 6A synchronous buck stage | Eliminates discrete MOSFETs and gate drivers; reduces BOM count by ≥7 components and PCB area by >40% vs. controller+MOSFET solutions. |

| I²C-programmable DVS slew rate (5.5–44 mV/μs) | Allows safe, controlled voltage transitions during processor frequency scaling without violating dV/dt limits on downstream capacitors. |
| Spread-spectrum modulation (+3%) | Reduces peak radiated EMI by >10dB at 2.2MHz fundamental and harmonics-meets CISPR 25 Class 5 requirements without added shielding. |
| AEC-Q100 Grade 0 qualification | Validated for -40°C to +125°C operation with lifetime reliability testing; suitable for engine control, radar, and camera modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4436AGL-A-Z | 4A rated, 2.2MHz, no I²C interface, no remote sensing, QFN-13 (3x4mm) | Suitable for cost-sensitive non-automotive applications where DVS and precision load-point regulation are not required. | Select when I²C control and ±2% accuracy at point-of-load are unnecessary; lower BOM cost but limited feature set. |

FAQ
What is the maximum output current capability of the MAX20010CATPQ/V+?
The MAX20010CATPQ/V+ delivers up to 6A continuous output current with integrated high-side and low-side MOSFETs. This rating is validated across the full -40°C to +125°C operating temperature range and with proper PCB thermal design-including use of the exposed pad (EP) tied to PGND and adequate copper pour. Derating applies above +70°C ambient per the 30.3mW/°C thermal coefficient.
Does the MAX20010CATPQ/V+ support dynamic voltage scaling (DVS) via I²C?
Yes, the MAX20010CATPQ/V+ supports full dynamic voltage scaling via its standard-compliant I²C interface. Output voltage can be adjusted in real time between 0.5V and 1.27V in 10mV steps-or 0.625V to 1.5875V in 12.5mV steps-using the VID register (0x07). Slew rate is independently programmable via the SLEW register (0x05) from 5.5 to 44 mV/μs.
What package type and thermal characteristics does the MAX20010CATPQ/V+ use?
The MAX20010CATPQ/V+ uses a 20-pin TQFN-EP package (4mm × 4mm, 0.5mm pitch) with exposed thermal pad. Its thermal resistance is θJA = 33°C/W and θJC = 2°C/W on a four-layer board. The EP must be soldered to a solid PGND plane for optimal heat dissipation and electrical performance-failure to do so risks thermal shutdown under sustained 6A load.
How does the MAX20010CATPQ/V+ handle overcurrent and short-circuit conditions?
Under overcurrent or short-circuit conditions, the MAX20010CATPQ/V+ triggers cycle-by-cycle current limiting at ~9.7A (typ). If VOUT drops below 50% of the target and current limit persists after soft-start, the device shuts down for 4ms and restarts soft-start. This hiccup-mode protection prevents thermal runaway and enables self-recovery once the fault is cleared-no external circuitry required.
Is the MAX20010CATPQ/V+ qualified for automotive applications?
Yes, the MAX20010CATPQ/V+ is AEC-Q100 qualified (Grade 0: -40°C to +150°C junction), with full validation for automotive use cases including engine control units, ADAS cameras, radar modules, and infotainment systems. It meets stringent requirements for ESD immunity, thermal cycling, and long-term reliability under harsh environmental stress.
