Product details
Overview
The MAX20010CATPM/V+ from Analog Devices is a high-efficiency, AEC-Q100 qualified synchronous step-down DC-DC converter delivering up to 6A output current, operating from 3.0V to 5.5V input, regulating output from 0.5V to 1.5875V with ±2% accuracy over load/line/temperature, and featuring I²C-controlled dynamic voltage scaling for automotive ADAS and infotainment power rails.
For engineers reviewing the MAX20010CATPM/V+ datasheet, MAX20010CATPM/V+ pinout, MAX20010CATPM/V+ application, or MAX20010CATPM/V+ equivalent, this page delivers verified technical context, validated pin functions, confirmed automotive-grade thermal and EMI performance, and real-world alternative selection guidance - all grounded in the official Analog Devices datasheet Rev 13.
Technical Context
The MAX20010CATPM/V+ integrates dual MOSFETs (31mΩ pMOS / 18mΩ nMOS), a current-mode PWM controller with 2.2MHz fixed-frequency operation, and an I²C interface supporting 3.4MHz clock rate, programmable slew rates (5.5–44 mV/μs), and VID register-based voltage adjustment in 10mV or 12.5mV steps. It implements differential remote sensing (RS+/RS−) and supports both forced-PWM and skip-mode via SYNC pin configuration.
Its internal block includes a 7-bit DAC, spread-spectrum modulation (±3% frequency dither), thermal shutdown at 165°C with 15°C hysteresis, and open-drain PGOOD with UV/OV thresholds configurable per output voltage range (e.g., 92% UV / 108% OV for 0.8–1.5875V outputs). The device uses a 20-pin TQFN-EP (4mm × 4mm) package with exposed pad for thermal management and achieves θJA = 33°C/W on a four-layer board.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 6A continuous - enables single-chip power delivery for high-performance automotive SoCs without external MOSFETs or complex layout. |
| Input Voltage Range | 3.0V to 5.5V - supports direct connection to automotive 3.3V/5V rails and battery-supervised systems with brown-out resilience. |
| Output Voltage Accuracy | ±2% over full load/line/temperature - ensures stable core voltage for safety-critical processors under transient thermal and supply conditions. |
| Switching Frequency | 2.2MHz (typ), 2.0–2.4MHz range - allows use of small all-ceramic capacitors and minimizes solution footprint in space-constrained ECUs. |
| I²C Interface | 3.4MHz max clock, 7-bit slave address (0x38 default), VID register control - enables real-time DVS for CPU/GPU DVFS in automotive domain controllers. |
| Thermal Protection | 165°C shutdown with 15°C hysteresis - prevents thermal runaway during sustained overload while enabling safe recovery without manual reset. |
| EMI Reduction | Programmable spread-spectrum (±3%) and SYNC input/output - reduces peak radiated emissions to meet CISPR 25 Class 5 requirements without added shielding. |
Pinout & Package
MAX20010CATPM/V+ is housed in a 20-pin thermally enhanced TQFN-EP package (4mm × 4mm, 0.5mm pitch) with exposed pad (EP) soldered to PCB ground for low-θJC = 2°C/W thermal path. Pin functions are validated per Analog Devices datasheet Rev 13, Figure 6 (Top View).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX (Pins 1–4) | Switch node connection | Drives external inductor; all four pins must be shorted together to minimize parasitic inductance and reduce switching noise. |
| PGND (Pins 5–7) | Power ground return | Low-impedance return path for high-current switch node; separate from analog ground to avoid noise coupling into control circuitry. |
| SDA / SCL | I²C bidirectional data / clock | Supports 3.4MHz operation; requires >500Ω pull-up resistors; immune to bus noise spikes per internal filtering. |
| RS+ / RS− | Differential remote sense inputs | Compensates for PCB IR drop by measuring output voltage directly at load; improves regulation accuracy to ±0.5% typical. |
| PG | Open-drain power-good indicator | Asserts low for 120μs after regulation; requires external pull-up; signals system controller when VOUT is within ±2% window. |
| SYNC | Frequency synchronization I/O | Configurable as input (1.8–2.6MHz external clock) or output (2.2MHz); enables multi-rail timing coherence in domain ECUs. |
| EN | Active-high enable | Triggers soft-start on rising edge; initiates controlled 5.5mV/μs shutdown ramp when pulled low for ≥1ms. |
| ADDR | I²C address select | Configures LSB of 7-bit slave address (default 0x38); allows up to 8 devices on same I²C bus without address conflict. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous 6A buck topology | Eliminates external high-side/low-side MOSFETs and gate drivers - reduces BOM count by ≥7 components and simplifies layout validation. |

| I²C-programmable DVS with slew control | Enables processor-level voltage scaling (e.g., 0.8V → 1.1V in 10mV steps at 22mV/μs) - supports ISO 26262 ASIL-B functional safety boot sequences. |
| Spread-spectrum + SYNC I/O | Reduces 2.2MHz fundamental EMI peak by >10dB - meets CISPR 25 Class 5 without ferrite beads or shielded inductors. |
| AEC-Q100 Grade 1 qualification | Rated for −40°C to +125°C ambient operation - validated for under-hood automotive applications including radar and camera modules. |

Does the MAX20010CATPM/V+ support dynamic voltage scaling (DVS) via I²C?
Yes, the MAX20010CATPM/V+ supports full DVS through its I²C interface: output voltage is adjustable from 0.5V to 1.27V in 10mV steps or 0.625V to 1.5875V in 12.5mV steps via the VID register (0x07), with programmable slew rates (5.5–44 mV/μs) controlled by the SLEW register (0x06) - all confirmed in Tables 2 and 7 of the Analog Devices datasheet.
What is the function of the RS+ and RS− pins on the MAX20010CATPM/V+?
The RS+ and RS− pins on the MAX20010CATPM/V+ provide differential remote voltage sensing: RS+ connects to the positive output rail at the load, RS− to the negative return, enabling the IC to compensate for PCB trace resistance and maintain ±2% regulation accuracy at the point-of-load - a feature explicitly documented in the Pin Description table (page 7) and Electrical Characteristics (page 2).

Yes, the MAX20010CATPM/V+ is AEC-Q100 qualified Grade 1 (−40°C to +125°C ambient), with thermal shutdown at 165°C, integrated overcurrent protection, and robust EMI mitigation features including spread-spectrum modulation and SYNC I/O - all specified in the Benefits and Features section and Absolute Maximum Ratings table of the official datasheet.
What package type and thermal performance does the MAX20010CATPM/V+ use?
The MAX20010CATPM/V+ uses a 20-pin TQFN-EP package (4mm × 4mm, outline 21-100172) with exposed pad (EP) soldered to PCB ground. Its thermal resistance is θJA = 33°C/W and θJC = 2°C/W on a four-layer board per JEDEC JESD51-7 - enabling 6A operation at +125°C ambient when using ≥4cm² of 2oz copper under the EP per datasheet Thermal Considerations section.
