Product details
Overview
The MAX20010DATPR/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 operation, I²C-controlled dynamic voltage scaling, and AEC-Q100 Grade 0 qualification (−40°C to +125°C).
For engineers reviewing the MAX20010DATPR/V+ datasheet, MAX20010DATPR/V+ pinout, MAX20010DATPR/V+ application, or MAX20010DATPR/V+ equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade protections (PGOOD, OCP, OTP), real-world transient performance data, and two rigorously cross-checked alternative parts for design-in flexibility.
Technical Context
This IC implements current-mode control with integrated high-side (31mΩ typ) and low-side (18mΩ typ) MOSFETs, enabling up to 6A continuous output at high efficiency. Its 2.2MHz switching frequency supports all-ceramic output filtering and minimizes solution footprint, while programmable spread-spectrum modulation reduces peak EMI by ±3%.
The device integrates differential remote sensing (RS+/RS−), programmable soft-start/slew rates (5.5–44 mV/μs), and dual-mode operation-forced-PWM (FPWM) for noise-sensitive systems or skip mode for light-load efficiency. SYNC pin supports both master clock synchronization and slave clock output, and the I²C interface (up to 3.4MHz) enables dynamic voltage adjustment in 10mV or 12.5mV steps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 6A continuous - supports high-power SoC core rails without external MOSFETs or heatsinks. |
| Input Voltage Range | 3.0V to 5.5V - compatible with automotive 3.3V/5V supply rails and battery-backed systems. |
| Output Voltage Accuracy | ±2% over full load/line/temperature - ensures stable processor core voltage under worst-case conditions. |
| Switching Frequency | 2.2MHz (±10%) - enables compact 1.0μH inductors and eliminates audible noise in vehicle cabins. |
| I²C Interface | Up to 3.4MHz - allows fast DVS during CPU DVFS transitions without bus contention. |
| Thermal Rating | AEC-Q100 Grade 0 (−40°C to +125°C TJ) - qualified for engine bay and ADAS ECU placement. |
| Protection Features | OCP (9.7A typ), OTP (165°C), PGOOD with 120μs delay - enables robust fault handling in safety-critical systems. |
Pinout & Package
20-pin TQFN-EP (4mm × 4mm, 0.5mm pitch) with exposed thermal pad (EP). RoHS-compliant, moisture sensitivity level 3 (MSL3), reflow-compatible per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX (Pins 1–4) | Switch node connection | Drives external power inductor; must be short, low-inductance trace to minimize switching losses and EMI. |
| PGND (Pins 5–7) | Power ground return | Low-impedance path for high di/dt currents; requires solid copper pour under package and direct connection to LX capacitor ground. |
| SDA / SCL (Pins 8–9) | I²C bidirectional data/clock | Supports system-level voltage sequencing and runtime margining; pullups required (≥500Ω) on both lines. |
| RS+ / RS− (Pins 10–11) | Differential remote sense inputs | Compensates for PCB IR drop across long traces-critical for sub-1V core rail accuracy in ADAS processors. |
| PG (Pin 12) | Open-drain power-good indicator | Signals valid regulation after 120μs timeout; requires external pullup to logic rail (e.g., 3.3V) for host MCU monitoring. |
| EN (Pin 13) | Active-high enable | Controls soft-start initiation; minimum 1ms low pulse required for complete soft-shutdown before re-enable. |
| SYNC (Pin 14) | Frequency sync I/O | Configurable as input (1.8–2.6MHz external clock) or output (2.2MHz internal clock) for multi-rail synchronization. |
| GND (Pin 15) | Analog ground reference | Separate from PGND to isolate noise-sensitive feedback and control circuitry from high-current paths. |
| AV (Pin 16) | Analog supply filter input | Must be decoupled with 100Ω resistor + 1μF ceramic cap to GND-prevents switching noise from corrupting internal references. |
| ADDR (Pin 17) | I²C address select | Sets LSB of 7-bit slave address (0x38–0x3F); enables multiple MAX20010 devices on same I²C bus without conflict. |
| PV (Pins 18–20) | Main power input | Accepts 3.0–5.5V; requires ≥4.7μF ceramic capacitor directly at pin to suppress high-frequency ripple and ensure stability. |
| EP | Exposed thermal pad | Must be soldered to solid GND plane-provides primary thermal path (θJC = 2°C/W) and improves power dissipation by >40%. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 6A synchronous buck | Eliminates need for external high-side/low-side MOSFETs and gate drivers-reduces BOM count by ≥7 components and layout area by >35%. |
| ±2% output voltage accuracy | Guaranteed across −40°C to +125°C, 0–6A load, and 3.0–5.5V input-meets tight core rail tolerances for automotive SoCs (e.g., TI Jacinto, NXP S32G). |
| Differential remote sensing | Compensates for up to 50mV IR drop between regulator and load-ensures <1% error at point-of-load even with 2-inch PCB traces. |
| Programmable DVS slew rate | Adjustable from 5.5 to 44 mV/μs via I²C register SLEW-enables precise timing alignment with CPU DVFS state transitions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 6A automotive buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62933RGER | 3.0–5.5V input, 0.4–1.5V output, 6A, 2.25MHz, no I²C, only analog VID pins | Lacks dynamic voltage scaling and remote sensing-suitable for fixed-voltage rails only | Select when I²C control and DVS are unnecessary; offers lower quiescent current (25μA) in shutdown. |
| MPQ4436AGRE-A | 3.0–36V input, 0.8–6.0V output, 6A, 2.2MHz, AEC-Q100 Grade 1 (−40°C to +125°C), no I²C | Wider input range but lower accuracy (±3%) and no remote sensing-better for 12V battery-fed pre-regulation | Choose for 12V/24V automotive systems requiring single-stage conversion; not suitable for precision core rails. |
Compared with the MAX20010DATPR/V+, the TPS62933RGER trades I²C programmability for lower static power, while the MPQ4436AGRE-A sacrifices output accuracy and sensing capability for broader input voltage support-neither offers the combined AEC-Q100 Grade 0 rating, ±2% accuracy, and differential remote sensing of the MAX20010DATPR/V+.

FAQ
What is the maximum continuous output current of the MAX20010DATPR/V+?
The MAX20010DATPR/V+ delivers up to 6A continuous output current under typical thermal conditions (four-layer board, 20°C ambient). This rating is validated across the full −40°C to +125°C operating temperature range and assumes proper PCB layout with the exposed pad soldered to a thermal plane. Peak current capability reaches 9.7A before overcurrent protection triggers.
Does the MAX20010DATPR/V+ support dynamic voltage scaling (DVS) via I²C?
Yes, the MAX20010DATPR/V+ supports full dynamic voltage scaling through its standard I²C interface. Output voltage can be adjusted in real time from 0.5V to 1.27V in 10mV steps or from 0.625V to 1.5875V in 12.5mV steps using the VID register (0x07). Slew rate is independently programmable via the SLEW register (0x05) to match processor DVFS timing requirements.
What package type and thermal characteristics does the MAX20010DATPR/V+ use?
The MAX20010DATPR/V+ uses a 20-pin TQFN-EP package (4mm × 4mm, 0.5mm pitch) with an exposed thermal pad. Its thermal resistance is θJA = 33°C/W and θJC = 2°C/W on a four-layer JEDEC-standard board. The exposed pad must be soldered to a dedicated GND plane to achieve rated power dissipation and maintain junction temperature below 150°C at 6A load.
Is the MAX20010DATPR/V+ qualified for automotive applications?
Yes, the MAX20010DATPR/V+ is AEC-Q100 qualified Grade 0 (−40°C to +125°C junction temperature), making it suitable for under-hood and safety-critical automotive applications including ADAS cameras, radar modules, and domain controllers. It includes automotive-specific protections: PGOOD with 120μs delay, overtemperature shutdown at 165°C, and short-circuit current limiting.
How does the MAX20010DATPR/V+ handle light-load efficiency?
The MAX20010DATPR/V+ automatically enters skip mode during light-load operation to maximize efficiency, reducing quiescent current to 300μA typical. Skip mode is enabled by default when the SYNC pin is left floating or pulled low; forced-PWM mode is activated when SYNC is driven high or connected to an external clock source (1.8–2.6MHz), ensuring consistent switching frequency for noise-sensitive systems.
