Product details
Overview
The MAX20010CATPU/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 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 is designed for automotive point-of-load regulation in ADAS and infotainment systems.
For engineers reviewing the MAX20010CATPU/V+T datasheet, MAX20010CATPU/V+T pinout, MAX20010CATPU/V+T application, or MAX20010CATPU/V+T equivalent, this page delivers verified electrical specs, validated pin functions, confirmed automotive-grade thermal and protection features, and real-world substitution guidance - all grounded in the official Analog Devices datasheet Rev 13 (2025).
Technical Context
This IC implements a current-mode, fixed-frequency (2.2MHz) PWM controller with selectable forced-PWM or skip-mode operation, enabling low-noise performance and high light-load efficiency. Its internal pMOS/nMOS power switches feature RDS(ON) of 31mΩ/18mΩ (typ), supporting full 6A continuous output without external FETs.
Differential remote sensing (RS+/RS−), programmable soft-start/slew rates (5.5–44 mV/μs), and integrated protections-including overcurrent (9.7A typ), overtemperature (165°C shutdown), and PGOOD with UV/OV thresholds-ensure robust operation in harsh automotive environments (-40°C to +125°C).

Pinout & Package
MAX20010CATPU/V+T 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 automotive reflow profiles (260°C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX (Pins 1–4) | Switch node connection | Drives external inductor; must be short, low-inductance trace to minimize EMI and switching losses |
| PGND (Pins 5–7) | Power ground return | Low-impedance return path for high-current switch node; separate from analog ground (GND) |
| SDA / SCL | I²C bidirectional data/clock | Enable dynamic voltage adjustment and status readback; require ≥500Ω pullups |
| RS+ / RS− | Differential remote sense inputs | Compensate for IR drop across PCB traces to maintain ±2% regulation at load point |
| PG | Open-drain power-good output | Signals valid VOUT after 120μs delay; requires external pullup to logic supply |
| EN | Active-high enable | Initiates soft-start (140μs delay); low state triggers controlled 5.5mV/μs shutdown ramp |
| SYNC | Frequency synchronization I/O | Configurable as input (1.8–2.6MHz external clock) or output (2.2MHz PWM sync signal) |
| ADDR | I²C address select | Sets LSB of 7-bit slave address (0x38–0x3F); allows multiple devices on same bus |
| AV / PV / GND | Analog supply / power input / analog ground | Separate AV filtering (100Ω + 1μF) improves noise immunity; PV bypass ≥4.7μF ceramic required |

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, 2.2MHz, but lacks differential remote sensing and AEC-Q100 qualification | Targeted at industrial/commercial, not automotive; no PGOOD timeout or thermal hysteresis spec | Select only for non-automotive designs where cost is prioritized over automotive reliability and precision |
| MPQ4436AGL-AEC1-Z | AEC-Q100 Grade 1 (–40°C to +125°C), 6A, 2.2MHz, but uses external compensation and lacks I²C interface | No dynamic voltage scaling; requires additional op-amps and resistors for remote sensing | Choose when I²C control is unnecessary and design team prefers traditional loop compensation tuning |
Compared with TPS62933RGER and MPQ4436AGL-AEC1-Z, the MAX20010CATPU/V+T uniquely combines AEC-Q100 Grade 0 qualification, integrated differential sensing, and I²C-based DVS in a single 4mm × 4mm package - making it the only option for ASIL-B-compliant, space-constrained automotive SoC core rails requiring real-time voltage adaptation.

FAQ
What is the maximum continuous output current supported by the MAX20010CATPU/V+T?
The MAX20010CATPU/V+T supports up to 6A continuous output current under specified thermal conditions (θJA = 33°C/W on 4-layer board, TA ≤ +70°C). At higher ambient temperatures or with reduced airflow, derating applies - e.g., ~4.5A at +105°C ambient. The device includes overcurrent protection that trips at 9.7A (typ) to safeguard against short circuits.
Does the MAX20010CATPU/V+T support dynamic voltage scaling (DVS) via I²C?
Yes, the MAX20010CATPU/V+T supports full dynamic voltage scaling via its standard I²C interface. Output voltage can be adjusted from 0.5V to 1.27V in 10mV steps or 0.625V to 1.5875V in 12.5mV steps using the VID register (0x06). Slew rate is independently programmable (5.5–44 mV/μs) via the SLEW register (0x05) to prevent system instability during transitions.
What package type and thermal characteristics does the MAX20010CATPU/V+T use?
The MAX20010CATPU/V+T uses a 20-pin TQFN-EP package (4mm × 4mm, 0.5mm pitch) with exposed thermal pad (EP). Its thermal resistance is θJA = 33°C/W and θJC = 2°C/W on a standard 4-layer JEDEC board. The EP must be soldered to a solid PGND plane to achieve rated performance and meet AEC-Q100 thermal stress requirements.
Is the MAX20010CATPU/V+T AEC-Q100 qualified, and what grade does it meet?
Yes, the MAX20010CATPU/V+T is AEC-Q100 qualified and certified to Grade 0 (–40°C to +150°C junction, –40°C to +125°C ambient). This qualification covers stress tests including HTOL, TC, UHAST, and ESD (HBM 2kV, CDM 1kV), confirming suitability for under-hood and safety-critical automotive applications such as ADAS and powertrain interfaces.
How does the MAX20010CATPU/V+T handle power-good signaling and fault detection?
The MAX20010CATPU/V+T provides an open-drain PGOOD output that asserts low for 120μs after VOUT enters regulation, then goes high when within ±2% of target. It also integrates a STATUS register (0x03) reporting real-time faults: UV, OV, OC, VRHOT, and VMERR. These flags persist until cleared by read, enabling precise root-cause diagnostics in automotive firmware.
