Product details
Overview
The MAX20010CATPQ/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, spread-spectrum modulation, and AEC-Q100 qualification for under-hood applications.
For engineers reviewing the MAX20010CATPQ/V+T datasheet, MAX20010CATPQ/V+T pinout, MAX20010CATPQ/V+T application, or MAX20010CATPQ/V+T equivalent, key selection considerations include its 20-pin TQFN-EP package with exposed thermal pad, I²C-controlled dynamic voltage scaling (DVS) in 10mV/12.5mV steps, differential remote sensing, and integrated overcurrent/overtemperature protections - all critical for ADAS power rail design and automotive SoC core supply.
Technical Context
This IC implements a current-mode, synchronous buck architecture with integrated high-side (31mΩ typ) and low-side (18mΩ typ) MOSFETs, enabling high-efficiency conversion at heavy loads. Its dual-mode operation-forced-PWM (2.2MHz) for transient response and skip mode for light-load efficiency-supports stable regulation across wide dynamic current ranges typical in automotive microprocessor cores.
The device integrates a 7-bit DAC for I²C-programmable output voltage, configurable soft-start/slew rates (5.5–44 mV/μs), and a dedicated SYNC I/O pin supporting both external clock synchronization and master-mode frequency output. Remote sense inputs (RS+, RS−) enable precise regulation at the load, while PGOOD provides open-drain status signaling with 120μs delay after regulation.
Key Specifications

| Package | 20-pin TQFN-EP (4mm × 4mm, 0.5mm pitch) with exposed thermal pad - provides low θJA = 33°C/W for passive heatsinking in space-constrained modules. |
Pinout & Package
MAX20010CATPQ/V+T is housed in a 20-pin thermally enhanced TQFN package (4mm × 4mm, 0.5mm pitch) with an exposed pad (EP) soldered to PCB ground for optimal thermal performance. The package complies with JEDEC MO-220 and RoHS standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX (Pins 1–4) | Switch node connection | Drives external inductor; all four pins must be shorted together to minimize parasitic inductance and improve EMI. |
| PGND (Pins 5–7) | Power ground return | Low-impedance path for high-current switch return; separate from analog ground to prevent noise coupling. |
| SDA / SCL (Pins 8–9) | I²C bidirectional data/clock | Supports 3.4MHz operation; requires external pullups >500Ω; immune to bus noise via internal spike suppression. |
| RS+/RS− (Pins 10–11) | Differential remote sense inputs | Compensates for IR drop across PCB traces; enables ±0.5% regulation accuracy at point-of-load. |
| PG (Pin 12) | Open-drain power-good output | Asserts low when VOUT is outside 89–111% window; includes 120μs blanking after startup to avoid false faults. |
| EN (Pin 13) | Active-high enable | Triggers soft-start on rising edge; initiates controlled 5.5mV/μs shutdown ramp when pulled low. |
| SYNC (Pin 14) | Frequency sync I/O | Configurable as input (1.8–2.6MHz external clock) or output (2.2MHz PWM signal) for system-level timing coordination. |
| GND (Pin 15) | Analog ground reference | Isolated ground for sensitive analog circuitry; must be connected separately from PGND near AV pin. |
| AV (Pin 16) | Analog supply input | Filtered via 100Ω resistor + 1μF ceramic cap to GND; powers internal reference and error amplifier for precision regulation. |
| ADDR (Pin 17) | I²C address select | Configures LSB of 7-bit slave address (0x38–0x3F); enables multiple devices on same I²C bus without conflict. |
| PV (Pins 18–20) | Main power input | Accepts 3.0–5.5V; requires ≥4.7μF ceramic capacitor per pin to PGND for high-frequency decoupling. |
| EP | Exposed thermal pad | Must be soldered to solid copper pour tied to PGND; primary heat dissipation path (θJC = 2°C/W). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62933RGER | 3.0–5.5V input, 6A output, 2.2MHz, but lacks remote sensing and AEC-Q100 qualification; uses different I²C register map. | Targeted at industrial/commercial systems; not validated for automotive temperature or reliability stress tests. | Select only if AEC-Q100 compliance and differential sensing are unnecessary and cost is primary driver. |
| MPQ4433AGRE-A | 3.0–36V input, 6A output, 2.2MHz, AEC-Q100 qualified, but no I²C interface or programmable DVS; fixed-output variants only. | Used in automotive body electronics with wide-input needs; unsuitable for dynamic voltage scaling in compute-intensive domains. | Choose when input voltage exceeds 5.5V or when I²C control and fine-grained voltage adjustment are not required. |
Compared with TPS62933RGER and MPQ4433AGRE-A, the MAX20010CATPQ/V+T uniquely combines AEC-Q100 Grade 0 qualification, I²C-programmable DVS with remote sensing, and integrated 2.2MHz spread-spectrum operation - making it the only option among the three suitable for safety-critical ADAS SoC core rails requiring both precision regulation and real-time voltage agility.

FAQ
What is the maximum output current capability of the MAX20010CATPQ/V+T?
The MAX20010CATPQ/V+T delivers up to 6A of continuous output current under specified thermal conditions (TA ≤ +70°C, 4-layer board). Its integrated 31mΩ high-side and 18mΩ low-side MOSFETs sustain this current with high efficiency, and thermal shutdown activates at 165°C junction temperature to protect against overload or poor heatsinking. Derating applies above +70°C ambient per the 30.3mW/°C thermal coefficient.
Does the MAX20010CATPQ/V+T support remote voltage sensing?
Yes, the MAX20010CATPQ/V+T supports true differential remote voltage sensing via dedicated RS+ and RS− pins. This feature compensates for voltage drop across PCB traces and interconnects, enabling ±0.5% regulation accuracy at the load point rather than at the IC's VOUT pin - critical for high-current automotive SoC applications where trace resistance can cause significant IR loss.
What I²C voltage step sizes does the MAX20010CATPQ/V+T support for dynamic voltage scaling?
The MAX20010CATPQ/V+T supports two programmable I²C voltage step sizes: 10mV steps for outputs between 0.5V and 1.27V, and 12.5mV steps for outputs between 0.625V and 1.5875V. The VSTEP bit in the CONFIG register selects the mode, allowing precise DVS control aligned with processor VID requirements while maintaining compatibility with common automotive SoC voltage tables.
How is the MAX20010CATPQ/V+T synchronized with other converters in a multi-rail system?
The MAX20010CATPQ/V+T uses its bidirectional SYNC pin for system-level synchronization: configured as an input, it accepts external clocks from 1.8MHz to 2.6MHz to force fixed-frequency PWM mode; configured as an output, it drives the SYNC pin of other MAX20010 devices or compatible converters at 2.2MHz. This eliminates beat frequencies and reduces conducted/radiated EMI in complex multi-converter automotive power systems.
Is the MAX20010CATPQ/V+T qualified for automotive use?
Yes, the MAX20010CATPQ/V+T is AEC-Q100 qualified for Grade 0 (-40°C to +125°C ambient), including full stress testing for temperature cycling, high-temperature operating life (HTOL), and electrostatic discharge. Its 20-pin TQFN-EP package with exposed thermal pad, integrated protections (overcurrent, overtemperature, UV/OV), and PGOOD output meet ISO 26262 ASIL-B readiness requirements for automotive power subsystems.
