Product details
Overview
MAX20010DATPT/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 over 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, spread-spectrum modulation, and AEC-Q100 qualification.
For engineers reviewing the MAX20010DATPT/V+T datasheet, MAX20010DATPT/V+T pinout, MAX20010DATPT/V+T application, or MAX20010DATPT/V+T equivalent, this page delivers verified technical context, validated pin functions, confirmed automotive-grade performance specs (including remote sensing, PGOOD, thermal shutdown), and real-world alternative selection guidance - all grounded in official Analog Devices documentation.
Technical Context
The MAX20010DATPT/V+T implements a current-mode, synchronous buck architecture 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 all-ceramic output filtering and minimizes solution footprint.
It integrates differential remote voltage sensing (RS+/RS−), programmable soft-start/slew rates (5.5–44 mV/μs), and dual-mode operation: forced-PWM (FPWM) for noise-sensitive systems and skip mode for light-load efficiency. The I²C interface (up to 3.4MHz) enables dynamic voltage scaling with 10mV or 12.5mV resolution depending on VSTEP configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 6A continuous - supports high-power microcontrollers and SoCs in automotive ECUs without external heatsinking. |
| Input Voltage Range | 3.0V to 5.5V - compatible with 3.3V/5V automotive rails and battery-supplied systems with transient tolerance. |
| Output Voltage Range | 0.5V to 1.5875V - covers core voltages for modern ADAS processors, FPGAs, and DSPs with fine-grained I²C control. |
| Voltage Accuracy | ±2% over load/line/temp - ensures stable supply under wide operating conditions, critical for functional safety compliance. |
| Switching Frequency | 2.2MHz (±10%) - enables compact 1.0µH–2.2µH inductors and eliminates audible noise in cabin applications. |

Pinout & Package
MAX20010DATPT/V+T is housed in a 20-pin, 4mm × 4mm TQFN-EP package (exposed pad) with thermal resistance θJA = 33°C/W on a 4-layer board. Pin assignments are validated per Analog Devices' official pin configuration diagram (Rev 13, p.6).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX (Pins 1–4) | Switch node connection | Drives external inductor; must be short, low-inductance routing to minimize switching losses and EMI. |
| PGND (Pins 5–7) | Power ground return | Low-impedance path for high-current switch return; separate from analog ground to avoid noise coupling. |
| SDA / SCL | I²C bidirectional data / clock | Supports dynamic voltage scaling and status readback; requires ≥500Ω pull-up resistors per bus specification. |
| RS+ / RS− | Differential remote sense inputs | Compensates for PCB IR drop at load; enables ±0.5% regulation accuracy at point-of-load. |
| PG | Open-drain power-good indicator | Asserts after 120μs when VOUT enters regulation window; used for system sequencing and fault monitoring. |
| EN | Active-high enable input | Initiates soft-start (ramp rate programmable); 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 internal PWM) for multi-rail timing alignment. |
| ADDR | I²C address select | Sets LSB of 7-bit slave address (0x38–0x3F); enables multiple devices on same I²C bus without conflict. |
| AV / GND / PV | Analog supply / analog ground / power input | Separate AV/GND paths isolate noise-sensitive reference circuitry; PV requires ≥4.7µF ceramic decoupling. |
| EP | Exposed thermal pad | Mandatory connection to PGND plane; primary heat dissipation path - improves θJC to 2°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 6A synchronous buck stage | Eliminates need for external MOSFETs and gate drivers - reduces BOM count, layout area, and design risk. |
| Differential remote sensing (RS+/RS−) | Compensates for up to 100mV PCB trace drop - maintains tight regulation at CPU/FPGA VDD pins despite long traces. |
| Programmable DVS slew rate (5.5–44 mV/μs) | Enables safe, glitch-free voltage transitions during processor DVFS - prevents undershoot/overshoot-induced crashes. |
| AEC-Q100 Grade 0 qualification | Validated for -40°C to +125°C operation with thermal shutdown (165°C), short-circuit protection, and robust ESD immunity. |
| Spread-spectrum + FPWM/skip modes | Reduces peak EMI by >10dB while maintaining <1% output ripple in FPWM - meets CISPR 25 Class 5 requirements. |
| Power-good with timeout and blanking | PG asserts only after stable regulation and ignores transients during voltage slewing - prevents false system resets. |

FAQ
What is the maximum output current capability of the MAX20010DATPT/V+T?
The MAX20010DATPT/V+T delivers up to 6A of continuous output current under thermal-limited conditions (θJA = 33°C/W, TA ≤ +70°C). This is achieved using integrated 31mΩ (pMOS) and 18mΩ (nMOS) switches, eliminating external power components. Derating applies above +70°C ambient per the 30.3mW/°C thermal coefficient specified in the Absolute Maximum Ratings table.
Does the MAX20010DATPT/V+T support remote voltage sensing?
Yes, the MAX20010DATPT/V+T supports true differential remote voltage sensing via dedicated RS+ and RS− pins. This feature compensates for IR drop across PCB traces, enabling ±0.5% regulation accuracy at the load point - critical for powering sensitive ADAS processors where local feedback would introduce unacceptable error.
How is output voltage programmed on the MAX20010DATPT/V+T?
Output voltage on the MAX20010DATPT/V+T is programmed via its I²C interface using the VID register (0x06). Two step sizes are supported: 10mV steps (0.5V–1.27V range) or 12.5mV steps (0.625V–1.5875V range), selected by the VSTEP bit in the CONFIG register (0x05). Factory-preset options are also available per Ordering Information, but I²C allows full runtime flexibility.
What protection features does the MAX20010DATPT/V+T include?
The MAX20010DATPT/V+T integrates overcurrent protection (trip threshold 7.76–11.64A), overtemperature shutdown (165°C with 15°C hysteresis), short-circuit recovery (4ms off-time + restart), and comprehensive I²C-accessible status monitoring (UV, OV, OC, VRHOT bits in STATUS register 0x03). These features meet functional safety requirements for automotive ASIL-B systems.
Is the MAX20010DATPT/V+T AEC-Q100 qualified?
Yes, the MAX20010DATPT/V+T is AEC-Q100 qualified per Grade 0 (-40°C to +125°C ambient), with full validation including HTOL, TC, UHAST, and ESD testing. This qualification is explicitly stated in the "Benefits and Features" section and confirmed in the "Absolute Maximum Ratings" table, supporting its use in under-hood and safety-critical automotive applications.
