Product details
Overview
The MAX20010EATPA/V+ from Analog Devices is a high-efficiency, synchronous 6A step-down DC-DC converter designed for automotive point-of-load regulation. It operates from 3.0V to 5.5V input, delivers 0.5V–1.5875V output with ±2% accuracy over load/line/temperature, features 2.2MHz fixed-frequency PWM, I²C-controlled dynamic voltage scaling (DVS), and AEC-Q100 Grade 0 qualification for under-hood applications.
For engineers reviewing the MAX20010EATPA/V+ datasheet, MAX20010EATPA/V+ pinout, MAX20010EATPA/V+ application, or MAX20010EATPA/V+ equivalent, key selection considerations include its 20-pin TQFN-EP package with exposed thermal pad, integrated pMOS/nMOS switches (31mΩ/18mΩ typ), programmable soft-start/slew rate, spread-spectrum EMI reduction, and remote differential voltage sensing for precision regulation in ADAS and infotainment power rails.
Technical Context
The MAX20010EATPA/V+ implements current-mode control with forced-PWM, skip-mode, and synchronization capability via its dual-function SYNC pin. Its internal 7-bit DAC enables precise I²C-programmable output voltage adjustment in either 10mV steps (0.5V–1.27V) or 12.5mV steps (0.625V–1.5875V), while the dedicated RS+/RS− pins support Kelvin remote sensing to eliminate PCB trace IR drop errors.
Thermal management is enhanced by an exposed pad (EP) thermally connected to the die substrate, achieving θJA = 33°C/W on a four-layer board. Protection includes cycle-by-cycle overcurrent limiting (9.7A typ), thermal shutdown at 165°C with 15°C hysteresis, and open-drain PGOOD with UV/OV window detection (±8% to ±12% depending on VOUT range).

Pinout & Package
MAX20010EATPA/V+ uses a 20-pin, 4mm × 4mm TQFN-EP package (package code T2044+4C) with exposed thermal pad (EP) soldered to PCB ground plane for optimal heat dissipation. Pin functions are validated per Analog Devices' official pin configuration diagram and electrical characteristics table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX (Pins 1–4) | Switch node connection | Drives external inductor; all four pins must be shorted together for low-inductance, high-current return path. |
| PGND (Pins 5–7) | Power ground reference | Separate low-impedance return for high di/dt switching currents; must be tied to EP and system PGND. |
| SDA / SCL (Pins 8–9) | I²C bidirectional data/clock | Supports up to 3.4MHz operation; requires external pull-ups >500Ω for noise immunity in automotive EMI environments. |
| RS+ / RS− (Pins 10–11) | Differential remote sense inputs | Compensates for PCB trace resistance between IC and load; enables <1% total output error at point-of-load. |
| PG (Pin 12) | Open-drain power-good indicator | Asserts low after 120μs when VOUT enters regulation window; requires external pull-up for logic-level interfacing. |
| EN (Pin 13) | Active-high enable | Initiates soft-start on rising edge; minimum 1ms low pulse required for complete soft-shutdown sequence. |
| SYNC (Pin 14) | Configurable sync I/O | Factory-set as input or output; accepts 1.8–2.6MHz external clocks or outputs internal 2.2MHz PWM for multi-rail synchronization. |
| GND (Pin 15) | Analog ground reference | Isolated from PGND to minimize noise coupling into sensitive analog blocks (EAMP, reference, ADC). |
| AV (Pin 16) | Analog supply input | Filtered via 100Ω resistor + 1μF ceramic cap to GND; powers internal reference and control circuitry for stability. |
| ADDR (Pin 17) | I²C address select | Configures LSB of 7-bit slave address (0x38–0x3F); allows up to 8 devices on same I²C bus without conflict. |
| PV (Pins 18–20) | Main power input | Accepts 3.0–5.5V; requires ≥4.7μF ceramic capacitor to PGND per pin for high-frequency decoupling. |
| EP | Exposed thermal pad | Must be soldered to solid copper thermal plane; provides primary thermal path (θJC = 2°C/W) and mechanical anchoring. |

FAQ
What is the maximum output current capability of the MAX20010EATPA/V+?
The MAX20010EATPA/V+ delivers up to 6A of continuous output current under specified thermal conditions (θJA = 33°C/W on four-layer board, TA ≤ +70°C). Its integrated 31mΩ pMOS and 18mΩ nMOS switches sustain this current with minimal conduction loss, and cycle-by-cycle overcurrent protection triggers at 9.7A typical to prevent damage during fault conditions. The MAX20010EATPA/V+ maintains regulation across the full 0.5V–1.5875V output range at 6A.
Does the MAX20010EATPA/V+ support dynamic voltage scaling (DVS) via I²C?
Yes, the MAX20010EATPA/V+ supports full I²C-controlled dynamic voltage scaling. Using its SDA/SCL pins and configurable ADDR pin, users can program the output voltage from 0.5V to 1.27V in 10mV steps or from 0.625V to 1.5875V in 12.5mV steps. The slew rate of voltage transitions is independently programmable (5.5–44mV/μs) via register 0x05, enabling precise matching to processor DVFS timing requirements without external components.
What package type and thermal characteristics does the MAX20010EATPA/V+ use?
The MAX20010EATPA/V+ uses a 20-pin, 4mm × 4mm TQFN-EP package (outline 21-100172) with an exposed thermal pad (EP). Its thermal resistance is θJA = 33°C/W and θJC = 2°C/W on a standard four-layer PCB. The EP must be soldered to a solid copper thermal plane connected to PGND for effective heat dissipation, enabling reliable operation at +125°C ambient and +150°C junction temperature as required by AEC-Q100 Grade 0.
How does the MAX20010EATPA/V+ achieve low electromagnetic interference (EMI)?
The MAX20010EATPA/V+ reduces EMI through three integrated features: (1) 2.2MHz fixed-frequency PWM operation enabling small, low-ESR ceramic capacitors; (2) programmable ±3% spread-spectrum modulation to lower peak radiated emissions; and (3) frequency synchronization I/O (SYNC pin) allowing multiple converters to operate in phase alignment, eliminating beat frequencies. These features collectively help meet CISPR 25 Class 5 radiated emissions limits without additional filtering or shielding.
Is the MAX20010EATPA/V+ qualified for automotive applications?
Yes, the MAX20010EATPA/V+ is AEC-Q100 qualified to Grade 0 (−40°C to +150°C junction temperature), making it suitable for under-hood and powertrain applications. It includes automotive-specific protections: open-drain PGOOD with UV/OV window detection, thermal shutdown with 15°C hysteresis, short-circuit protection with auto-retry, and robust I/O voltage tolerances (e.g., SDA/SCL rated to +6V). Its 20-pin TQFN-EP package is optimized for vibration resistance and thermal reliability in harsh automotive environments.
