Product details
Overview
The MAX20010CATPL/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 Grade 1 qualification (−40°C to +125°C).
For engineers reviewing the MAX20010CATPL/V+T datasheet, MAX20010CATPL/V+T pinout, MAX20010CATPL/V+T application, or MAX20010CATPL/V+T equivalent, key selection considerations include its integrated 6A power stage, differential remote sensing, I²C-controlled dynamic voltage scaling (DVS) with 10mV/12.5mV steps, forced-PWM/skip-mode operation, and automotive-grade thermal and fault protection.
Technical Context
This IC implements a current-mode, synchronous buck topology with integrated high-side (31mΩ typ) and low-side (18mΩ typ) MOSFETs, enabling high-efficiency conversion at heavy loads. Its 2.2MHz switching frequency supports all-ceramic output filtering and minimizes solution footprint while maintaining robust transient response-especially in MAX20010D/E variants.
The device integrates dual-mode control logic: fixed-frequency PWM for noise-sensitive systems and pulse-frequency modulation (skip mode) for light-load efficiency. I²C interface enables real-time voltage adjustment, soft-start slew rate programming, spread-spectrum enable/disable, and status register readback-including overvoltage, undervoltage, overcurrent, and thermal-fault flags.
Key Specifications

Pinout & Package
MAX20010CATPL/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 dissipation (θJA = 33°C/W on 4-layer board). Pin functions 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 di/dt currents; separate from analog ground (GND) to avoid noise coupling. |
| SDA / SCL (Pins 8–9) | I²C bidirectional data/clock | Supports up to 3.4MHz clock; requires pull-up resistors (>500Ω); enables dynamic voltage scaling and telemetry. |
| RS+/RS− (Pins 10–11) | Differential remote sense inputs | Compensates for IR drop across PCB traces; improves output regulation accuracy at load point. |
| PG (Pin 12) | Open-drain power-good indicator | Asserts low after 120µs when VOUT enters ±5% regulation window; requires external pull-up for logic-level signaling. |
| EN (Pin 13) | Active-high enable | Initiates soft-start on rising edge; triggers controlled 5.5mV/µs shutdown ramp when pulled low. |
| SYNC (Pin 14) | Frequency synchronization I/O | Configurable as input (accepts 1.8–2.6MHz external clock) or output (2.2MHz PWM signal) for multi-rail coherence. |
| GND (Pin 15) | Analog ground reference | Isolated ground for internal reference and error amplifier; connects to system AGND plane, not PGND. |
| AV (Pin 16) | Analog supply input | Filtered via 100Ω resistor + 1µF ceramic cap to GND; powers precision internal circuitry independent of noisy PV rail. |
| ADDR (Pin 17) | I²C address select | Configures 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 heat path (θJC = 2°C/W) and mechanical stability. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous 6A power stage | Integrated pMOS (31mΩ) and nMOS (18mΩ) switches eliminate external FETs and gate drivers, reducing BOM count and layout complexity. |
| Differential remote sensing | RS+/RS− inputs compensate for PCB trace resistance, maintaining ±2% regulation accuracy even with >100mΩ interconnect impedance. |
| I²C-controlled DVS with slew rate programming | VID register (0x07) sets output voltage; SLEW register (0x05) configures soft-start and DVS ramp rates from 5.5 to 44 mV/µs. |
| Automotive-grade protection suite | Includes overcurrent latch-off (9.7A threshold), thermal shutdown (165°C), PGOOD with blanking during slewing, and UVLO (2.85V rising). |
| EMI-reduction architecture | 2.2MHz fixed frequency + ±3% spread-spectrum modulation + SYNC I/O capability collectively suppress radiated emissions below CISPR-25 Class 5 limits. |

The MAX20010CATPL/V+T delivers up to 6A of continuous output current under thermal and voltage conditions specified in the datasheet (TA ≤ +125°C, VIN = 5V, VOUT = 1.0V). This rating assumes proper PCB thermal design-including soldering the exposed pad (EP) to a minimum 200mm² copper area-and use of recommended external components (e.g., 1.0µH inductor, 22µF ceramic output capacitors). The device includes overcurrent protection that trips at ~9.7A typical to safeguard against short-circuit events.
Does the MAX20010CATPL/V+T support dynamic voltage scaling (DVS) via I²C?
Yes, the MAX20010CATPL/V+T supports full dynamic voltage scaling through its standard-compliant I²C interface.

Slew rate during DVS transitions is independently programmable via the SLEW register (0x05), enabling controlled ramping from 5.5 to 44 mV/µs.
What package type and thermal characteristics does the MAX20010CATPL/V+T have?
The MAX20010CATPL/V+T uses a 20-pin TQFN-EP package measuring 4mm × 4mm with 0.5mm pitch and an exposed thermal pad (EP). On a standard 4-layer JEDEC PCB, its junction-to-ambient thermal resistance (θJA) is 33°C/W, and junction-to-case (θJC) is 2°C/W. The EP must be soldered to a dedicated ground plane for effective heat dissipation. This package meets AEC-Q100 Grade 1 requirements and supports operation from −40°C to +125°C ambient temperature.
How does the MAX20010CATPL/V+T handle electromagnetic interference (EMI)?
The MAX20010CATPL/V+T incorporates three hardware-level EMI mitigation techniques: (1) 2.2MHz fixed switching frequency enabling small passive components and reduced energy in lower-frequency bands; (2) programmable ±3% spread-spectrum modulation to lower peak radiated emissions; and (3) SYNC I/O pin supporting frequency synchronization across multiple rails to avoid beat-frequency harmonics. These features collectively help meet stringent automotive CISPR-25 Class 5 radiated emissions limits without requiring additional shielding or filtering.
Is the MAX20010CATPL/V+T qualified for automotive applications?
Yes, the MAX20010CATPL/V+T is AEC-Q100 qualified to Grade 1 (−40°C to +125°C ambient), with built-in protections including overtemperature shutdown (165°C), overcurrent limiting (~9.7A), input undervoltage lockout (2.85V rising), and open-drain PGOOD output with UV/OV detection.
