Product details
Overview
The MAX20010DATPO/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 MAX20010DATPO/V+ datasheet, MAX20010DATPO/V+ pinout, MAX20010DATPO/V+ application, or MAX20010DATPO/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 official Analog Devices documentation.
Technical Context
The MAX20010DATPO/V+ implements a current-mode, fixed-frequency (2.2MHz typ) PWM architecture with selectable forced-PWM or skip-mode operation, integrated pMOS/nMOS switches (RDS(ON) = 31mΩ / 18mΩ), and differential remote sensing for precision regulation under PCB trace resistance. Its SYNC pin supports both master clock synchronization and slave mode frequency locking.
It integrates programmable soft-start (via SLEW register), spread-spectrum modulation (±3% frequency dither), and comprehensive protection including overcurrent (9.7A typ trip), overtemperature shutdown (165°C), and PGOOD monitoring with UV/OV thresholds configurable per output voltage range. The device uses a 7-bit I²C interface (up to 3.4MHz) with ADDR-pin-selectable slave address (0x38–0x3F write).

Pinout & Package
MAX20010DATPO/V+ is housed in a 20-pin TQFN-EP package (4mm × 4mm, 0.5mm pitch) with exposed thermal pad (EP) connected to PGND. The package supports high-power dissipation (θJA = 33°C/W on 4-layer board) and meets automotive mechanical robustness requirements.
| 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 switching loss. |
| PGND (Pins 5–7) | Power ground return | Low-impedance path for high di/dt currents; separate from AGND to prevent noise coupling into analog circuitry. |
| SDA / SCL | I²C bidirectional data / clock | Supports up to 3.4MHz communication; requires ≥500Ω pull-up resistors; immune to bus noise via internal spike suppression. |
| RS+/RS- | Differential remote sense inputs | Compensates for IR drop across PCB traces, enabling ±0.5% regulation accuracy at point-of-load. |
| PG | Open-drain power-good indicator | Asserts low for 120μs after regulation; requires external pull-up; provides system sequencing feedback with UV/OV fault detection. |
| SYNC | Frequency sync I/O | Configurable as input (accepts 1.8–2.6MHz external clock) or output (2.2MHz PWM signal) for multi-rail synchronization. |
| EN | Active-high enable | Triggers soft-start on rising edge; initiates controlled 5.5mV/μs shutdown ramp when pulled low for >1ms. |
| AV / PV / GND | Analog supply / power input / analog ground | AV filtered via 100Ω + 1μF to GND; PV bypassed with ≥4.7μF ceramic to PGND; GND isolated from PGND for noise separation. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous 6A buck topology | Eliminates external high-side/low-side MOSFETs and drivers, reducing BOM count by ≥7 components and PCB area by >40% vs discrete solutions. |
| 2.2MHz fixed-frequency PWM | Enables compact all-ceramic filter design (no electrolytics), reduces EMI fundamental frequency above AM band, and improves transient response <10μs. |
| Programmable spread-spectrum | Reduces peak radiated emissions by >10dB at 2.2MHz harmonics - critical for CISPR 25 Class 5 automotive EMC compliance. |
| I²C-controlled DVS with 10/12.5mV steps | Allows runtime voltage adjustment for processor DVFS, reducing dynamic power by up to 35% during low-load states without hardware change. |
| AEC-Q100 Grade 0 qualification | Validated for -40°C to +125°C operation with 100% production testing, ensuring reliability in safety-critical ADAS camera, radar, and domain controller applications. |

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, only resistor-programmed VOUT | Lacks dynamic voltage scaling; suitable for fixed-voltage rails only | Select when cost sensitivity outweighs need for DVS and automotive qualification is secondary |
| TPS62933RQYR | 6A, 2.5MHz, I²C-compatible but not AEC-Q100 qualified; lower RDS(ON) (16/9mΩ) | Higher efficiency at light loads due to advanced DCS-Control™, but unqualified for automotive temperature range | Prefer for industrial or consumer applications requiring tighter light-load regulation and higher switching frequency |
Compared with MPQ4436AGL-A-Z and TPS62933RQYR, the MAX20010DATPO/V+ uniquely combines AEC-Q100 Grade 0 qualification, I²C-based DVS, and integrated remote sensing - making it the only choice for safety-critical automotive SoC core rails where voltage agility and thermal reliability are non-negotiable.

FAQ
What is the factory-preset output voltage for MAX20010DATPO/V+?
The MAX20010DATPO/V+ does not have a factory-preset output voltage - it is a blank variant ('V+' suffix) configured exclusively via I²C. Unlike MAX20010D variants with fixed VOUT options (e.g., 0.85V, 1.0V), the MAX20010DATPO/V+ requires initialization of the VID register (0x07) after power-up to set the target output voltage between 0.5V and 1.5875V in 10mV or 12.5mV steps.
Does MAX20010DATPO/V+ support spread-spectrum operation, and how is it enabled?
Yes, the MAX20010DATPO/V+ supports spread-spectrum frequency modulation to reduce EMI peaks. It is enabled by setting bit CONFIG.SS = 1 (bit 1 of register 0x05), which dithers the 2.2MHz switching frequency by ±3%. This feature is independent of SYNC configuration and remains active in both forced-PWM and skip modes.
What is the maximum allowable input voltage for MAX20010DATPO/V+?
The absolute maximum input voltage for MAX20010DATPO/V+ is 6V on PV and AV pins, but the recommended operational range is 3.0V to 5.5V. Exceeding 5.5V may trigger undervoltage lockout recovery instability or exceed safe operating area limits during transients, even though the device survives brief 6V excursions per Absolute Maximum Ratings.
How does the PGOOD (PG) pin behave during startup and fault conditions for MAX20010DATPO/V+?
The PGOOD pin on MAX20010DATPO/V+ asserts low for 120μs after VOUT enters regulation (within ±5% of target), then goes high open-drain. During undervoltage (UV) or overvoltage (OV) faults, PG pulls low immediately and remains low until VOUT returns to the valid window and the 120μs timer expires again. No external capacitor is needed - timing is internal and fixed.
Can MAX20010DATPO/V+ operate with only ceramic output capacitors?
Yes, the MAX20010DATPO/V+ is fully compatible with all-ceramic output capacitor designs due to its 2.2MHz fixed-frequency current-mode control and integrated compensation. A typical layout uses three 22μF 0805 X5R ceramics (total 66μF) with ESR <5mΩ - eliminating bulk electrolytics and improving reliability in automotive thermal cycling environments.
