Product details
Overview
MAX20010CATPE/V+T from Analog Devices is a fully integrated, AEC-Q100 qualified 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 operation with spread-spectrum modulation for automotive point-of-load regulation.
For engineers reviewing the MAX20010CATPE/V+T datasheet, MAX20010CATPE/V+T pinout, MAX20010CATPE/V+T application, or MAX20010CATPE/V+T equivalent, key selection criteria include its 20-pin TQFN-EP (4mm × 4mm) package, differential remote sensing capability, I²C-controlled dynamic voltage scaling (DVS), robust overcurrent/overtemperature protection, and compliance with automotive-grade thermal (-40°C to +125°C) and reliability requirements.
Technical Context
The MAX20010CATPE/V+T implements current-mode control with integrated high-side (31mΩ typ) and low-side (18mΩ typ) MOSFETs, enabling high-efficiency operation across 0–6A load range. Its 2.2MHz switching frequency supports all-ceramic output filtering and minimizes solution footprint while maintaining excellent load-transient response-enhanced in MAX20010D/E variants, though MAX20010C retains full transient capability per datasheet characterization.
It integrates dual operating modes: forced-PWM (FPWM) for consistent noise spectrum and skip mode for light-load efficiency, selectable via SYNC pin configuration or I²C register CONFIG[4]. The device supports synchronization to external clocks (1.8–2.6MHz), spread-spectrum modulation (±3%), and programmable soft-start/slew rates (5.5–44 mV/μs) through dedicated registers.
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 brownout margin. |
| Output Voltage Range | 0.5V–1.5875V, programmable in 10mV or 12.5mV steps - supports core voltage scaling for ADAS processors and microcontrollers. |
| Voltage Accuracy | ±2% over load/line/temp - ensures stable regulation under real-world automotive transients and thermal cycling. |
| Switching Frequency | 2.2MHz (typ), ±3% spread-spectrum - reduces EMI peak emissions and allows compact 1.0–2.2μH inductors with ceramic capacitors. |
| Package | 20-pin TQFN-EP (4mm × 4mm, 0.5mm pitch) with exposed pad - provides low θJA = 33°C/W for thermally demanding engine bay or infotainment applications. |
| I²C Interface | Up to 3.4MHz clock rate, 7-bit slave address (default 0x38 write / 0x70 read) - enables real-time DVS and telemetry in multi-rail power systems. |
Pinout & Package
MAX20010CATPE/V+T is housed in a 20-pin thermally enhanced thin quad flat no-lead package with exposed pad (TQFN-EP), outline number 21-100172, land pattern 90-0409. The exposed pad must be soldered to a PCB thermal plane for optimal junction-to-board heat transfer (θJC = 2°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–4, 18–20 (LX, PV) | Power switch node / Input supply | LX pins connect to inductor switch node; PV pins supply input power (3.0–5.5V) and require ≥4.7μF ceramic decoupling to PGND. |
| 5–7, EP (PGND, Exposed Pad) | Power ground return path | All PGND pins and EP must be connected to a low-impedance ground plane; EP is electrically tied to die substrate for thermal conduction. |
| 8–9 (SDA, SCL) | I²C bidirectional data/clock | Supports up to 3.4MHz communication; requires pull-up resistors (>500Ω) and noise filtering per automotive EMC standards. |
| 10–11 (RS−, RS+) | Differential remote sense inputs | Enable precise regulation at load by compensating for PCB trace IR drop; required for <±1% system-level accuracy. |
| 12 (PG) | Open-drain power-good indicator | Asserts low for 120μs after VOUT enters regulation window; requires external pull-up for logic-level signaling to host controller. |
| 13 (EN) | Active-high enable with soft-start | Initiates controlled 5.5–44 mV/μs output ramp; minimum 1ms low pulse ensures complete soft-shutdown before re-enable. |
| 14 (SYNC) | Configurable sync I/O | Factory-configured as input (accepts 1.8–2.6MHz clocks) or output (2.2MHz PWM); enables multi-phase or EMI-aligned timing. |
| 15 (GND) | Analog reference ground | Must be isolated from noisy PGND traces and connected to clean analog ground plane near AV and RS pins. |
| 16 (AV) | Analog supply filter input | Requires RC filter (100Ω + 1μF ceramic) from PV to suppress noise coupling into internal reference and error amplifier. |
| 17 (ADDR) | I²C address select | Configures LSB of 7-bit slave address (default A0=0 → 0x38); allows up to 8 devices on same I²C bus with unique VID settings. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade-1 qualification | Validated for -40°C to +125°C operation with lifetime reliability testing - meets automotive power management safety and longevity requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62933RGER | 3.0–5.5V input, 0.4–1.6V output, 3A max; 2.2MHz, I²C, but no remote sensing or spread-spectrum | Suitable for lower-current MCU rails where EMI headroom exists; lacks RS+/RS− for precision load regulation | Select when cost-sensitive, non-AEC-Q100 designs require basic DVS without automotive thermal or sensing rigor. |
| MPQ4433AGRE-A | 3.0–36V input, 0.8–6.0V output, 3.5A max; no I²C, no remote sensing, no spread-spectrum; AEC-Q100 Grade-1 | Fits wide-input industrial or body electronics; lacks programmability and precision needed for SoC core rails | Choose for simpler, fixed-output post-regulation in 12V/24V automotive subsystems where I²C control is unnecessary. |

FAQ
What is the factory-preset output voltage for MAX20010CATPE/V+T?
The MAX20010CATPE/V+T does not have a factory-preset output voltage; it is a programmable variant requiring I²C initialization to set VOUT. Its default power-on output is determined by the VID register contents (typically 0x00), which yields ~0.5V unless configured otherwise. Users must write to the VID register (0x07) via I²C to establish the desired output within the 0.5V–1.5875V range using 10mV or 12.5mV steps.
Does MAX20010CATPE/V+T support remote voltage sensing, and how is it implemented?
Yes, MAX20010CATPE/V+T supports differential remote voltage sensing via dedicated RS+ and RS− pins (pins 11 and 10). These inputs connect directly to the load's power and ground points, enabling the internal error amplifier to regulate VOUT at the load rather than at the IC's output pin. This compensates for PCB trace resistance and ensures ±2% accuracy at the point of use, critical for high-current SoC applications.
What protection features are integrated into MAX20010CATPE/V+T?
MAX20010CATPE/V+T integrates overcurrent protection (OCP) with hiccup-mode recovery, overtemperature shutdown (165°C trip with 15°C hysteresis), input undervoltage lockout (UVLO at 2.85V rising), and open-drain PGOOD monitoring with UV/OV thresholds. All protections are fully autonomous - no external components required - and status bits (OC, VRHOT, UV, OV) are readable via I²C STATUS register (0x03).
Can MAX20010CATPE/V+T synchronize to an external clock, and what is the acceptable frequency range?
Yes, MAX20010CATPE/V+T can synchronize to an external clock via the SYNC pin when configured as an input (factory setting for CATPE/V+T). It accepts input frequencies from 1.8MHz to 2.6MHz, allowing alignment with system clocks or adjacent regulators to reduce beat-frequency EMI. When used as an output, SYNC delivers the internal 2.2MHz PWM signal for multi-phase coordination.
Is MAX20010CATPE/V+T pin-compatible with other variants in the MAX20010 family?
Yes, MAX20010CATPE/V+T shares identical pinout, package (20-pin TQFN-EP), and footprint with MAX20010D and MAX20010E. All variants use the same LX, PV, PGND, RS+, RS−, PG, EN, SYNC, SDA, SCL, ADDR, AV, and GND assignments. Functional differences (e.g., transient response enhancement in D/E) do not affect mechanical or electrical interconnect compatibility.
