Product details
Overview
The MAX20010CATPX/V+T from Analog Devices is a high-efficiency, 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 EMI reduction - ideal for automotive ADAS power rails and processor core supplies.
For engineers reviewing the MAX20010CATPX/V+T datasheet, MAX20010CATPX/V+T pinout, MAX20010CATPX/V+T application, or MAX20010CATPX/V+T equivalent, key selection considerations include its 20-pin TQFN-EP (4mm × 4mm) package with exposed thermal pad, differential remote sensing capability, integrated pMOS/nMOS switches (RDS(ON) = 31/18 mΩ typ), and robust automotive-grade protections including overcurrent, overtemperature, and PGOOD monitoring.
Technical Context
This IC implements a current-mode, synchronous buck architecture with dual operating modes: forced-PWM (FPWM) for stable noise immunity and skip mode for light-load efficiency. Its internal 2.2MHz oscillator supports frequency synchronization via the SYNC pin (1.8–2.6MHz input range) and optional ±3% spread-spectrum modulation to suppress radiated emissions.
The device integrates precision analog functions including differential remote voltage sensing (RS+/RS−), programmable soft-start and dynamic voltage scaling (DVS) slew rates (5.5–44 mV/μs), and an open-drain PGOOD output with configurable OV/UV thresholds (±8% to ±12% depending on VOUT). All protections - thermal shutdown at 165°C, cycle-by-cycle current limiting (9.7A typ), and short-circuit recovery - are fully autonomous and require no external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.0V to 5.5V - supports direct connection to automotive battery rail (with transient clamping) and eliminates need for pre-regulator stages. |
| Output Current | Up to 6A continuous - enables single-chip power delivery for high-performance SoCs and radar processors without external MOSFETs. |
| Output Voltage Accuracy | ±2% over full load/line/temp - ensures reliable operation of sub-1V digital cores without margining overhead. |
| Switching Frequency | 2.2MHz (typ), fixed or synchronized - allows use of compact 0805/1206 ceramic inductors and reduces solution footprint by >40% vs. 500kHz designs. |
| RDS(ON) (High-Side) | 31 mΩ (typ at 5V) - minimizes conduction loss at 6A, enabling >92% peak efficiency at 12VIN/1.0VOUT/3A. |

Pinout & Package
MAX20010CATPX/V+T is housed in a thermally enhanced 20-pin TQFN-EP package (4mm × 4mm, 0.5mm pitch) with exposed copper pad (EP) for PCB-level heat dissipation. The package supports JEDEC-standard reflow and achieves θJA = 33°C/W on a four-layer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX (Pins 1–4) | Switch Node | Connects directly to inductor switch node; low-inductance routing critical for EMI control and efficiency - all four pins must be shorted on PCB. |
| PGND (Pins 5–7) | Power Ground Return | Primary return path for high-current switching loop; requires dedicated low-impedance polygon pour separate from analog ground. |
| SDA / SCL (Pins 8–9) | I²C Serial Interface | Supports 3.4MHz operation; SDA is open-drain, SCL is input-only - both require ≥500Ω pull-up resistors to AV or logic rail. |
| RS+ / RS− (Pins 10–11) | Differential Remote Sense Inputs | Enable precise regulation at point-of-load by compensating for IR drop across PCB traces - improves output accuracy by up to 15mV. |
| PG (Pin 12) | Open-Drain Power-Good | Asserts low when VOUT is outside ±8–12% window; includes 120μs blanking after startup and 5μs propagation delay for timing-critical sequencing. |
| EN (Pin 13) | Active-High Enable | Triggers soft-start on rising edge; minimum 1ms low pulse required for clean soft-shutdown to prevent PG glitching. |
| SYNC (Pin 14) | Frequency Sync I/O | Configurable as input (accepts 1.8–2.6MHz clock) or output (2.2MHz PWM signal); enables system-wide clock alignment for multi-rail noise reduction. |
| GND (Pin 15) | Analog Ground Reference | Separate from PGND to isolate noise-sensitive feedback and reference circuits - must connect to quiet ground plane near AV and RS pins. |
| AV (Pin 16) | Analog Supply Input | Filtered version of PV (via 100Ω + 1μF); powers internal reference, error amp, and ADC - decoupling prevents regulation instability. |
| ADDR (Pin 17) | I²C Address Select | Configures LSB of 7-bit slave address (0x38–0x3F); enables up to 8 devices on same bus without address conflict. |
| PV (Pins 18–20) | Main Power Input | Supplies gate drivers and high-side switch; requires ≥4.7μF ceramic capacitor placed within 2mm of pins to minimize high-frequency ripple. |
| EP | Exposed Thermal Pad | Must be soldered to solid copper thermal plane (≥4 thermal vias recommended); primary path for junction-to-board heat transfer - not electrically connected to GND or PGND. |
