Product details
Overview
MAX20010CATPW/V+T from Analog Devices is a synchronous step-down DC-DC converter IC designed for automotive point-of-load regulation, 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, and integrates low RDS(ON) pMOS/nMOS switches (55mΩ/31mΩ typ) for high efficiency in compact layouts.
For engineers reviewing the MAX20010CATPW/V+T datasheet, MAX20010CATPW/V+T pinout, MAX20010CATPW/V+T application, or MAX20010CATPW/V+T equivalent, this page delivers verified technical context on its AEC-Q100 qualified 20-pin TQFN-EP package, I²C-controlled dynamic voltage scaling, spread-spectrum EMI reduction, remote sensing capability, and robust protection features including overcurrent, overtemperature, and PGOOD monitoring.
Technical Context
The MAX20010CATPW/V+T implements current-mode control with integrated 2.2MHz oscillator and configurable SYNC I/O for forced-PWM or skip-mode operation. Its internal 7-bit DAC enables precise VOUT adjustment in 10mV or 12.5mV steps, while differential remote sensing (RS+/RS−) compensates for PCB IR drop in high-current automotive rails.
It integrates dual MOSFETs with 55mΩ pMOS and 31mΩ nMOS RDS(ON), supports soft-start slew rate programming (5.5–44 mV/μs), and provides real-time status reporting via I²C registers including OC, UV/OV, thermal fault, and VMERR flags - all operating within −40°C to +125°C junction range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.0V to 5.5V - supports direct connection to automotive battery-supplied 3.3V/5V rails without pre-regulation. |
| Output Current | Up to 6A continuous - sufficient for powering modern ADAS SoCs, radar processors, or infotainment domain controllers. |
| Output Voltage Accuracy | ±2% over load/line/temp - ensures stable core voltage for sensitive digital loads under dynamic conditions. |
| Switching Frequency | 2.2MHz (±10%) - enables use of small all-ceramic output capacitors and minimizes solution footprint. |
| I²C Interface | Up to 3.4MHz clock rate with 7-bit slave address (0x38–0x3F) - allows dynamic voltage scaling and real-time telemetry in multi-rail systems. |
| Thermal Protection | 165°C shutdown with 15°C hysteresis - prevents latch-up during sustained overload or ambient thermal stress. |
| EMI Reduction | Programmable ±3% spread-spectrum modulation - lowers peak radiated emissions without sacrificing regulation performance. |
Pinout & Package
MAX20010CATPW/V+T is housed in a 20-pin, 4mm × 4mm thermally enhanced TQFN-EP package (package code T2044+4C) with exposed pad (EP) soldered to ground for optimal thermal dissipation (θJA = 33°C/W on 4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–4, 18–20 (LX, PV) | Power switch node / Input supply | LX pins connect to inductor switch node; PV pins accept 3.0–5.5V input and require ≥4.7µF ceramic decoupling to PGND. |
| 5–7, EP (PGND) | Power ground return path | Low-impedance ground for high-current switching loop; EP must be connected to system ground for thermal and electrical integrity. |
| 8–9 (SDA, SCL) | I²C bidirectional data/clock | Supports 3.4MHz operation; requires external pullups >500Ω; tolerant of bus noise spikes per I²C spec. |
| 10–11 (RS−, RS+) | Differential remote sense inputs | Enable accurate regulation at load by measuring VOUT directly at point-of-load, rejecting PCB trace resistance error. |
| 12 (PG) | Open-drain power-good indicator | Asserts low when VOUT is outside 89–111% window (for 0.8–1.5875V outputs); includes 120µs delay after regulation. |
| 13 (EN) | Active-high enable with soft-start control | Triggers controlled 5.5–44 mV/μs ramp-up; minimum 1ms low pulse required for full soft-shutdown sequence. |
| 14 (SYNC) | Configurable synchronization I/O | Factory-programmable as input (1.8–2.6MHz external clock) or output (2.2MHz PWM frequency); enables multi-phase sync. |
| 15 (GND) | Analog reference ground | Separate from PGND to isolate noise-sensitive analog circuitry (EAMP, reference, DAC) from high-current switching paths. |
| 16 (AV) | Analog supply input | Filtered via 100Ω resistor + 1µF ceramic cap to GND; powers internal reference, comparators, and control logic. |
| 17 (ADDR) | I²C address select | Configures LSB of 7-bit slave address (0x38–0x3F); allows up to 8 devices on same I²C bus without conflict. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade-1 qualification | Validated for −40°C to +125°C operation - meets automotive reliability and lifetime requirements for engine bay and cabin applications. |
| Integrated MOSFETs with low RDS(ON) | pMOS = 55mΩ, nMOS = 31mΩ (typ at 5V) - eliminates external FETs and gate drivers, reducing BOM count and layout complexity. |
| Programmable DVS slew rate | Configurable from 5.5 to 44 mV/μs via SLEW register - prevents voltage droop/surge during processor DVFS transitions. |
| Dual-mode operation | Forced-PWM (low-noise, constant fSW) and skip mode (high-efficiency light-load) - selectable via CONFIG register or SYNC pin. |
| Comprehensive fault reporting | I²C-accessible STATUS register flags OC, UV, OV, VRHOT, and VMERR - enables predictive diagnostics and system-level fault recovery. |

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 |
|---|---|---|---|
| MPQ4436GL-AEC1-Z | 4A rated, 2.2MHz, no I²C interface; uses external compensation; lacks remote sensing. | Suitable for fixed-output, non-DVS applications where cost and simplicity outweigh programmability needs. | Select when I²C control and dynamic voltage scaling are unnecessary and 4A output suffices. |
| TPS6286418RTERQ1 | 6A rated, 2.2MHz, I²C-compatible but only 0.3–1.5V output range; no spread-spectrum; smaller 3mm × 3mm QFN. | Better for space-constrained designs needing identical 6A/2.2MHz performance but without EMI-sensitive environments. | Prefer when board area is critical and spread-spectrum EMI suppression is not required. |
Compared with MPQ4436GL-AEC1-Z and TPS6286418RTERQ1, the MAX20010CATPW/V+T uniquely combines 6A capability, full I²C programmability (including VIDMAX capping and status readback), differential remote sensing, and ±3% spread-spectrum - making it the only option among the three qualified for high-precision, EMI-sensitive, dynamically scaled automotive SoC rails.

FAQ
What is the maximum output current capability of the MAX20010CATPW/V+T?
The MAX20010CATPW/V+T delivers up to 6A of continuous output current under typical thermal conditions (θJA = 33°C/W on 4-layer board). This rating assumes proper PCB layout with adequate copper pour on PGND and EP, input/output capacitance per datasheet recommendations, and ambient temperature ≤ +85°C. At higher temperatures or reduced airflow, derating applies per thermal characteristics.
Does the MAX20010CATPW/V+T support remote voltage sensing?
Yes, the MAX20010CATPW/V+T supports true differential remote sensing using dedicated RS+ and RS− pins. This allows the IC to regulate voltage directly at the load point, compensating for voltage drop across PCB traces and connectors - critical for maintaining ±2% accuracy at high currents in automotive applications.
How is the output voltage programmed on the MAX20010CATPW/V+T?
The MAX20010CATPW/V+T supports both factory-preset and I²C-programmable output voltages. Via its 7-bit VID register (0x07), users can set VOUT from 0.5V to 1.27V in 10mV steps or 0.625V to 1.5875V in 12.5mV steps. The VSTEP bit (CONFIG register, bit 7) selects the step size, and slew rate is independently configured in the SLEW register (0x05).
What protection features does the MAX20010CATPW/V+T include?
The MAX20010CATPW/V+T integrates overcurrent (OC), overtemperature (VRHOT), output overvoltage (OV), undervoltage (UV), and VOUT-MAX violation (VMERR) protections. All faults are latched and reported via the STATUS register (0x03), and PGOOD deasserts during fault conditions. Short-circuit protection initiates automatic 4ms shutdown/restart cycles until fault clears.
Is the MAX20010CATPW/V+T AEC-Q100 qualified?
Yes, the MAX20010CATPW/V+T is AEC-Q100 qualified for Grade 1 (−40°C to +125°C ambient operation), with full qualification testing including HTOL, TC, UHAST, and ESD per automotive standards. This qualification covers the entire device - silicon, package, and assembly - and is documented in the official Analog Devices AEC-Q100 certificate.
