Product details
Overview
The MAX20010CATPM/V+T 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 across load, line, and temperature. It operates from 3.0V–5.5V input and supports programmable output voltages from 0.5V to 1.5875V via I²C, features 2.2MHz fixed-frequency PWM operation, spread-spectrum modulation, and differential remote sensing - optimized for automotive point-of-load regulation of ADAS processors and domain controllers.
For engineers reviewing the MAX20010CATPM/V+T datasheet, MAX20010CATPM/V+T pinout, MAX20010CATPM/V+T application, or MAX20010CATPM/V+T equivalent, key selection criteria include its 20-pin TQFN-EP (4mm × 4mm) package, I²C-controlled dynamic voltage scaling (DVS) with 10mV/12.5mV steps, forced-PWM/skip-mode operation, PGOOD signaling, and thermal shutdown at +165°C - all validated for -40°C to +125°C automotive environments.
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 conversion without external power switches. Its 2.2MHz switching frequency supports all-ceramic output filtering and minimizes solution footprint while maintaining robust load-transient response.
The device integrates dual-mode control logic: fixed-frequency PWM for noise-sensitive applications and pulse-frequency modulation (skip mode) for light-load efficiency. Synchronization I/O allows master-slave clock alignment, and programmable soft-start (via register-controlled slew rate) limits inrush current during power-up sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 6A continuous - supports high-power SoCs and microcontrollers without external heat sinking under typical automotive ambient conditions. |
| Input Voltage Range | 3.0V to 5.5V - compatible with 3.3V and 5V automotive supply rails, including post-regulation after primary 12V/48V DC-DC stages. |
| Output Voltage Accuracy | ±2% over full load/line/temp - ensures stable core voltage for safety-critical processors meeting ISO 26262 ASIL-B timing margins. |
| Switching Frequency | 2.2MHz (±10%) - enables compact 1.0µH inductors and eliminates audible noise; supports EMI-compliant layout with minimal filter area. |
| I²C Interface | Up to 3.4MHz clock rate - allows real-time DVS during processor DVFS transitions with <160ns setup/hold timing compliance. |
| Thermal Shutdown | +165°C with 15°C hysteresis - protects against sustained overload or poor PCB thermal design while permitting short-term peak power bursts. |
| Package | 20-pin TQFN-EP (4mm × 4mm, 0.5mm pitch) - exposes thermal pad for direct PCB ground connection, achieving θJA = 33°C/W on 4-layer board. |
Pinout & Package
MAX20010CATPM/V+T uses a 20-pin thermally enhanced TQFN package (outline 21-100172) with exposed pad (EP) connected to GND for optimal heat dissipation. The pinout supports differential remote sensing, I²C configuration, SYNC synchronization, and open-drain PGOOD signaling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–4, 18–20 (LX, PV) | Power switch node / Input supply | LX pins connect directly to inductor switch node; PV pins accept 3.0–5.5V input with local 4.7µF ceramic decoupling - low-inductance routing critical for EMI performance. |
| 5–7, EP (PGND) | Power ground return | Multiple PGND pins and exposed pad form low-impedance return path for high di/dt currents - must be tied to solid ground plane beneath IC. |
| 8–9 (SDA, SCL) | I²C bidirectional interface | Supports dynamic voltage adjustment and status readback; requires ≥500Ω pull-ups and noise-filtering per I²C spec - not compatible with SMBus Alert or general call. |
| 10–11 (RS−, RS+) | Differential remote sense inputs | Compensates for IR drop across PCB traces by measuring output voltage at load - improves regulation accuracy to ±0.5% at point-of-load. |
| 12 (PG) | Open-drain power-good output | Asserts low for 120µs after VOUT enters regulation window; requires external pull-up to logic rail - used for processor reset sequencing and system enable coordination. |
| 13 (EN) | Active-high enable input | Triggers soft-start on rising edge; minimum 1ms low pulse required for complete soft-shutdown - prevents premature PGOOD deassertion during re-enable. |
| 14 (SYNC) | Configurable sync I/O | Factory-set as input or output; accepts 1.8–2.6MHz external clocks or outputs internal 2.2MHz signal - enables multi-rail synchronization without jitter accumulation. |
| 15 (GND) | Analog ground reference | Separate AGND pin isolates sensitive analog circuitry (error amp, reference) from noisy power grounds - must be connected to PGND at single point near EP. |
| 16 (AV) | Analog supply input | Filtered via 100Ω resistor + 1µF ceramic cap to GND - supplies internal reference and control logic, rejecting PV supply noise. |
| 17 (ADDR) | I²C address select | Configures LSB of 7-bit slave address (0x38–0x3F); allows up to 8 devices on same bus - no pull-up/down required; logic level defines base address per Table 1. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade-1 qualification | Validated for -40°C to +125°C operation with lifetime reliability testing - meets automotive functional safety requirements for non-safety-critical power rails. |
| Programmable DVS slew rate | Configurable soft-start and voltage transition rates (5.5–44 mV/µs) via SLEW register - prevents overshoot/undershoot during processor frequency scaling. |
| Spread-spectrum modulation | ±3% frequency dithering reduces peak radiated emissions by >10dB at 2.2MHz fundamental - simplifies EMC certification without added shielding or filters. |
| Overcurrent protection | Peak-current limiting with automatic 4ms hiccup recovery - detects short circuits and sustains safe operation without latch-off or manual reset. |

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 |
|---|---|---|---|
| TPS62933RGER | 3.0–5.5V input, 6A output, 2.2MHz, but lacks I²C interface and remote sensing - only analog VID pins for preset voltage. | Suitable for fixed-voltage applications where DVS or precision remote sensing is unnecessary; lower BOM cost but less flexible. | Select when system does not require dynamic voltage scaling or load-point accuracy better than ±3%. |
| MPQ4436AGRE-A | 3.3–18V input, 6A output, 2.2MHz, AEC-Q100 Grade-1, includes I²C but no spread-spectrum or SYNC I/O - different thermal pad layout. | Better suited for wide-input applications (e.g., 12V battery-fed rails), but lacks EMI-reduction features critical for RF-sensitive modules. | Prefer when input voltage exceeds 5.5V or when footprint compatibility with MPQ4436-based designs is required. |

FAQ
What is the maximum output current capability of the MAX20010CATPM/V+T?
The MAX20010CATPM/V+T delivers up to 6A of continuous output current under typical automotive thermal conditions (TA = +70°C, 4-layer board). This rating assumes proper PCB layout with thermal vias under the exposed pad and adequate copper area for heat dissipation. At higher ambient temperatures or with reduced copper, derating applies per the thermal resistance data (θJA = 33°C/W).
Does the MAX20010CATPM/V+T support dynamic voltage scaling (DVS) via I²C?
Yes, the MAX20010CATPM/V+T supports full dynamic voltage scaling via its standard I²C interface. Output voltage can be adjusted in real time between 0.5V and 1.27V in 10mV steps, or between 0.625V and 1.5875V in 12.5mV steps, using the VID register (0x06). Slew rate is independently programmable via the SLEW register (0x05) to prevent overshoot during transitions.
What is the purpose of the RS+ and RS− pins on the MAX20010CATPM/V+T?
The RS+ and RS− pins on the MAX20010CATPM/V+T provide differential remote voltage sensing to compensate for IR drop across PCB traces between the regulator and load. By measuring feedback directly at the load, the IC maintains ±2% output regulation accuracy at the point-of-load - critical for high-current, low-voltage processor cores where even 50mΩ trace resistance causes significant voltage error.
How does the MAX20010CATPM/V+T handle overcurrent or short-circuit conditions?
Under overcurrent or short-circuit conditions, the MAX20010CATPM/V+T activates cycle-by-cycle current limiting. If VOUT drops below 50% of the target and current limit persists after soft-start, the device enters hiccup mode: it shuts down for 4ms (at 2.2MHz), then retries soft-start. This protects internal MOSFETs and external components while allowing automatic recovery once the fault clears - no manual reset required.
Is the MAX20010CATPM/V+T pin-compatible with other variants in the MAX20010 family?
Yes, the MAX20010CATPM/V+T shares identical pinout, package, and electrical interface with MAX20010D and MAX20010E variants. Differences lie in internal firmware tuning - MAX20010D/E offer improved transient response and optional spread-spectrum settings - but all three are mechanically and electrically interchangeable on the PCB without layout changes.
