Product details
Overview
MAX20010EATPA/V+T from Analog Devices is a 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 features 2.2MHz fixed-frequency PWM, spread-spectrum modulation, and differential remote sensing for automotive point-of-load regulation.
For engineers reviewing the MAX20010EATPA/V+T datasheet, MAX20010EATPA/V+T pinout, MAX20010EATPA/V+T application, or MAX20010EATPA/V+T equivalent, key selection considerations include AEC-Q100 qualification, I²C-controlled dynamic voltage scaling (DVS), forced-PWM/skip-mode operation, thermal shutdown at 165°C, and compatibility with all-ceramic output capacitors in compact 4mm × 4mm TQFN-EP packaging.
Technical Context
The MAX20010EATPA/V+T implements current-mode control with integrated high-side (31mΩ typ) and low-side (18mΩ typ) MOSFETs, enabling efficient 6A delivery without external power switches. Its 2.2MHz switching frequency supports small external inductors and ceramic capacitors, while programmable spread-spectrum modulation reduces peak EMI emissions by ±3%.
It integrates differential remote sense (RS+/RS−), open-drain PGOOD with 5µs UV/OV propagation delay, and configurable soft-start/slew rates (5.5–44 mV/µs). The I²C interface supports 3.4MHz clock rate, 7-bit slave address selection via ADDR pin, and register-level control of VID, CONFIG, SLEW, and STATUS-enabling precise DVS timing and fault monitoring in automotive ADAS and infotainment systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 6A continuous - enables single-chip power delivery for high-performance automotive SoCs and MCUs without external FETs. |
| Input Voltage Range | 3.0V to 5.5V - compatible with automotive 3.3V/5V rails and battery-supplied systems with transient tolerance. |
| Output Voltage Range | 0.5V to 1.5875V - covers core voltages for ARM Cortex-A/R processors and FPGA I/O banks with fine-grained I²C adjustment. |
| Switching Frequency | 2.2MHz (±10%) - allows use of ≤1µH inductors and eliminates electrolytic capacitors, reducing solution footprint. |
| Voltage Accuracy | ±2% (0.8V–1.5875V range) - ensures stable core supply under full load, line, and -40°C to +125°C conditions. |
| Thermal Protection | 165°C shutdown with 15°C hysteresis - prevents latch-up during sustained overload or poor heatsinking in engine bay environments. |
| I²C Interface | 3.4MHz max clock, 7-bit address with ADDR pin - supports real-time DVS sequencing and telemetry readback without dedicated PMBus controller. |
Pinout & Package
MAX20010EATPA/V+T is housed in a 20-pin, 4mm × 4mm TQFN-EP package with exposed pad (EP) for thermal dissipation. The package meets JEDEC MO-220 standards and supports four-layer PCB layout with θJA = 33°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX (Pins 1–4) | Switch node connection | Drives external inductor; all four pins must be shorted to minimize parasitic inductance and EMI. |
| PGND (Pins 5–7) | Power ground return | Low-impedance path for high di/dt currents; separate from analog ground to avoid noise coupling. |
| SDA / SCL | I²C bidirectional data / clock | Supports 3.4MHz operation; requires ≥500Ω pull-up resistors; immune to bus noise spikes per spec. |
| RS+ / RS− | Differential remote sense inputs | Compensates for PCB IR drop; enables ±0.5% regulation accuracy at load point, critical for low-voltage cores. |
| PG | Open-drain power-good indicator | Asserts after 120µs when VOUT enters regulation window; used for system power sequencing and fault detection. |
| EN | Active-high enable | Triggers soft-start on rising edge; minimum 1ms low pulse required for complete soft-shutdown before re-enable. |
| SYNC | Frequency synchronization I/O | Configurable as 1.8–2.6MHz input (FPWM mode) or 2.2MHz output (for multi-rail synchronization). |
| AV / GND / PV | Analog supply / analog ground / power input | Separate AV/GND routing required; PV decoupled with ≥4.7µF ceramic cap to PGND for stability. |
Key Features
| Feature | Design Value |
|---|---|

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4436AGL-A-Z | 4A rated, 2.2MHz, no I²C interface, no remote sensing, QFN-13 package | Lacks DVS and precision remote sensing - suitable only for fixed-output, non-automotive applications | Select only if I²C control and ±2% accuracy at point-of-load are unnecessary; lower cost but higher design risk in automotive systems. |

FAQ
What is the maximum output current capability of the MAX20010EATPA/V+T?
The MAX20010EATPA/V+T delivers up to 6A of continuous output current under thermal limits defined by its 4mm × 4mm TQFN-EP package and θJA = 33°C/W rating. This is validated across the full -40°C to +125°C operating temperature range with proper PCB copper area and airflow. The device includes internal current-limit protection triggered at 9.7A typical, ensuring safe operation during overload or short-circuit events without external components.
Does the MAX20010EATPA/V+T support dynamic voltage scaling (DVS) via I²C?
Yes, the MAX20010EATPA/V+T supports full dynamic voltage scaling through its standard-compliant I²C interface. Output voltage can be adjusted in real time between 0.5V and 1.27V in 10mV steps, or 0.625V to 1.5875V in 12.5mV steps, using the VID register (0x07). Slew rate is independently programmable (5.5–44 mV/µs) via the SLEW register (0x05), enabling controlled transitions that prevent logic glitches during CPU frequency scaling sequences.
What is the purpose of the RS+ and RS− pins on the MAX20010EATPA/V+T?
The RS+ and RS− pins on the MAX20010EATPA/V+T provide differential remote voltage sensing to compensate for IR drop across PCB traces between the regulator and load. By measuring voltage directly at the load point, the MAX20010EATPA/V+T maintains ±2% regulation accuracy regardless of trace resistance - critical for low-voltage, high-current applications like SoC core supplies. These pins must be routed as a matched pair, away from noisy switching nodes, and terminated at the load's power/ground planes.
Is the MAX20010EATPA/V+T qualified for automotive applications?
Yes, the MAX20010EATPA/V+T is AEC-Q100 Grade-1 qualified, meaning it is tested and certified for operation from -40°C to +125°C ambient temperature and meets stringent automotive reliability, ESD, and fault coverage requirements. It includes built-in protections such as overtemperature shutdown (165°C), overcurrent limiting, and open-drain PGOOD signaling - all essential for deployment in ADAS, infotainment, and body control modules within modern vehicles.
Can the MAX20010EATPA/V+T synchronize its switching frequency with other converters?
Yes, the MAX20010EATPA/V+T features a bidirectional SYNC pin that supports both master and slave operation. When configured as an input, it accepts external clock signals from 1.8MHz to 2.6MHz to force fixed-frequency PWM mode. When configured as an output (via CONFIG register bit SO[1:0] = 10), it drives the internal 2.2MHz switching frequency onto the SYNC line - enabling precise phase alignment across multiple rails in multi-converter systems such as automotive domain controllers.
