Product details
Overview
MAX20010CATPF/V+ 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 MAX20010CATPF/V+ datasheet, MAX20010CATPF/V+ pinout, MAX20010CATPF/V+ application, or MAX20010CATPF/V+ equivalent, this device is selected for high-precision, low-noise, thermally robust power delivery in ADAS domain controllers, infotainment SoC rails, and automotive camera modules requiring stable 0.8V–1.2V core supplies with dynamic voltage scaling and remote sensing.
Technical Context
The MAX20010CATPF/V+ implements current-mode control with integrated pMOS (31–55mΩ) and nMOS (18–31mΩ) power switches, enabling high-efficiency operation across 0–6A loads. Its 2.2MHz switching frequency supports all-ceramic output filtering and minimizes solution footprint while maintaining excellent load-transient response-especially critical for fast-dynamic processor cores.
It integrates differential remote voltage sensing (RS+/RS−), programmable soft-start/slew rates (5.5–44 mV/μs), and dual-mode operation: forced-PWM (FPWM) for noise-sensitive timing rails or skip mode for light-load efficiency. The I²C interface (up to 3.4MHz) enables real-time DVS, fault monitoring (OV/UV/OC/thermal), and configuration of spread-spectrum (±3%), SYNC I/O direction, and voltage-step resolution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 6A continuous - supports high-power automotive SoCs 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/temp - ensures reliable operation of sub-1V digital cores under worst-case conditions. |
| Switching Frequency | 2.2MHz (±10%) - enables compact 1.0μH inductors and eliminates audible noise in cabin applications. |
| I²C Interface | Up to 3.4MHz with 7-bit address + R/W bit - allows rapid DVS updates and real-time telemetry in multi-rail systems. |
| Thermal Rating | -40°C to +125°C ambient, 165°C junction shutdown - meets AEC-Q100 Grade 0 requirements for engine bay proximity. |
| Protection Features | Overcurrent (9.7A typ), overtemperature (165°C), PGOOD with 120μs delay, and UVLO (2.85V rising) - prevents system brownouts and thermal runaway. |
Pinout & Package
MAX20010CATPF/V+ uses a 20-pin TQFN-EP package (4mm × 4mm, 0.5mm pitch) with exposed thermal pad (EP) connected to PGND. Pin assignments 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; all four pins must be shorted to minimize parasitic inductance and EMI. |
| PGND (Pins 5–7) | Power ground return | Low-impedance path for high di/dt currents; separate from analog ground to avoid noise coupling. |
| SDA / SCL | I²C bidirectional data / clock | Supports 3.4MHz operation; requires ≥500Ω pull-up resistors; immune to bus noise spikes. |
| RS+ / RS− | Differential remote sense inputs | Compensates for PCB IR drop; enables ±0.5% regulation at load point instead of IC output pin. |
| PG | Open-drain power-good indicator | Asserts low for 120μs after VOUT enters regulation window; requires external pull-up for logic-level signaling. |
| EN | Active-high enable | Triggers soft-start on rising edge; initiates controlled 5.5mV/μs shutdown ramp when pulled low. |
| SYNC | Configurable sync I/O | Factory-set as input/output; accepts 1.8–2.6MHz external clocks or outputs internal 2.2MHz for multi-phase synchronization. |
| ADDR | I²C slave address select | Configures one of eight possible 7-bit addresses (0x38–0x3F); enables multiple devices on same bus. |
| AV / GND / PV | Analog supply / analog ground / power input | AV filtered via 100Ω + 1μF to GND; PV decoupled with ≥4.7μF ceramic to PGND; strict separation preserves feedback stability. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous 6A buck topology | Eliminates external high-side/low-side MOSFETs and gate drivers - reduces BOM count by ≥7 components and layout area by >40% vs discrete solutions. |

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 |
|---|---|---|---|
| MPQ4436AGL-A-Z | 4A rated, 2.2MHz, no I²C interface, no remote sensing, QFN-13 (3x4mm) | Lacks DVS and precision remote sensing - suitable only for static-voltage, lower-current applications like body control modules. | Select when cost sensitivity outweighs need for dynamic voltage scaling and ±0.5% load-point accuracy. |
| TPS6286418ARWYR | 6A rated, 2.25MHz, I²C interface, but no spread-spectrum, no differential sensing, WSON-16 (3x3mm) | Higher EMI risk in noise-sensitive domains; lacks thermal grade certification - limited to cabin interior applications. | Choose if footprint reduction is critical and AEC-Q100 Grade 0 compliance is not required. |
Compared with MPQ4436AGL-A-Z and TPS6286418ARWYR, the MAX20010CATPF/V+ uniquely combines AEC-Q100 Grade 0 qualification, differential remote sensing, programmable spread-spectrum, and 6A capability in a single 4mm×4mm package - making it the only option for safety-critical, high-accuracy, low-EMI automotive SoC rails.

FAQ
What is the factory-preset output voltage for MAX20010CATPF/V+?
The MAX20010CATPF/V+ does not have a factory-preset output voltage - it is configured exclusively via its I²C interface. Output voltage is set using the VID register (0x07) with resolution of either 10mV (VSTEP=0) or 12.5mV (VSTEP=1), covering 0.5V–1.27V or 0.625V–1.5875V ranges respectively. This enables flexible integration into multi-rail systems without hardware changes.
Does MAX20010CATPF/V+ support synchronization with external clock sources?
Yes, MAX20010CATPF/V+ supports external clock synchronization via its SYNC pin. When configured as an input (factory default for this variant), it accepts frequencies from 1.8MHz to 2.6MHz to force fixed-frequency PWM mode - eliminating beat frequencies in multi-converter systems and improving EMI predictability. The SYNC pin can also be configured as an output to drive other MAX20010 devices.
How does the differential remote sensing (RS+/RS−) improve regulation accuracy in MAX20010CATPF/V+?
The MAX20010CATPF/V+ uses RS+ and RS− pins to measure output voltage directly at the load, compensating for voltage drop across PCB traces and connectors. This achieves ±0.5% regulation accuracy at the point-of-load - significantly tighter than the ±2% accuracy referenced to the IC's VOUT pin - which is essential for sub-1V digital cores where 25mV deviation can cause functional failure.
What protection features are integrated into MAX20010CATPF/V+?
MAX20010CATPF/V+ integrates overcurrent protection (9.7A typical trip threshold), overtemperature shutdown (165°C with 15°C hysteresis), undervoltage lockout (2.85V rising), and open-drain PGOOD with 120μs delay. It also monitors output overvoltage/undervoltage via dedicated comparators and reports faults through the STATUS register (0x03), enabling system-level error recovery without external supervision circuits.
Is MAX20010CATPF/V+ pin-compatible with other variants in the MAX20010 family?
Yes, MAX20010CATPF/V+ shares identical 20-pin TQFN-EP (4mm × 4mm) packaging and pinout with MAX20010D and MAX20010E variants. All share the same LX, PGND, SDA, SCL, RS+, RS−, PG, EN, SYNC, ADDR, AV, GND, and PV pin assignments. Functional differences (e.g., transient response tuning) are implemented internally and do not affect PCB layout or interconnect design.
