Product details
Overview
The MAX20010CATPF/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 MAX20010CATPF/V+T datasheet, MAX20010CATPF/V+T pinout, MAX20010CATPF/V+T application, or MAX20010CATPF/V+T equivalent, this page delivers verified technical context on its I²C-configurable voltage regulation, remote sensing capability, thermal shutdown behavior, and automotive-grade protection features - all critical for ADAS power rail design, infotainment SoC core supply, and ECU post-regulation.
Technical Context
The MAX20010CATPF/V+T integrates high-side and low-side MOSFETs with RDS(ON) of 31mΩ (pMOS) and 18mΩ (nMOS) at 5V, enabling high-efficiency conversion at full 6A load. Its current-mode control architecture supports forced-PWM, skip-mode, and frequency synchronization via the bidirectional SYNC pin.
It implements differential remote voltage sensing (RS+/RS−), programmable soft-start/slew rates (5.5–44 mV/μs), and real-time status monitoring via I²C registers including OV/UV/OC/thermal fault flags. The device uses a 7-bit I²C slave address configurable via ADDR pin, with default write address 0x70 and read address 0x71.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.0V to 5.5V - supports direct connection to automotive 3.3V/5V rails without pre-regulation. |
| Output Current | Up to 6A - sufficient for powering modern automotive SoCs, GPUs, and DSPs in ADAS modules. |
| Output Voltage Accuracy | ±2% over load/line/temp - ensures stable core voltage for processors requiring tight regulation windows. |
| Switching Frequency | 2.2MHz (typ), ±3% spread-spectrum - enables use of small ceramic capacitors and reduces EMI filtering burden. |

Pinout & Package
MAX20010CATPF/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. 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; requires low-inductance routing to minimize switching losses and EMI. |
| PGND (Pins 5–7) | Power ground return | Separate low-impedance path for high-current switch node return; must be tied to EP and PV decoupling ground plane. |
| SDA / SCL (Pins 8–9) | I²C serial interface | Enable dynamic voltage adjustment and fault register reads; require ≥500Ω pull-ups per I²C spec. |
| RS+ / RS− (Pins 10–11) | Differential remote sense inputs | Compensate for PCB trace IR drop to maintain ±2% regulation at load point, not at IC pins. |
| PG (Pin 12) | Open-drain power-good indicator | Asserts low for 120μs after VOUT enters regulation window; requires external pull-up for logic-level signaling. |
| EN (Pin 13) | Active-high enable | Initiates soft-start on rising edge; minimum 1ms low pulse required for complete soft-shutdown sequence. |
| SYNC (Pin 14) | Frequency sync I/O | Configurable as input (1.8–2.6MHz external clock) or output (2.2MHz internal PWM); controls FPWM/skip mode. |
| GND (Pin 15) | Analog ground reference | Isolated from PGND to reduce noise coupling into feedback and control circuits. |
| AV (Pin 16) | Analog supply input | Filtered separately (100Ω + 1μF) from PV to stabilize internal reference and error amplifier. |
| ADDR (Pin 17) | I²C address select | Sets LSB of 7-bit slave address (default 0x38 → write 0x70); enables multiple devices on same bus. |
| PV (Pins 18–20) | Main power input | Supplies internal circuitry and high-side FET gate drive; requires ≥4.7μF ceramic capacitor to PGND. |
| EP | Exposed thermal pad | Must be soldered to solid copper thermal plane; provides primary heat conduction path (θJC = 2°C/W). |

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 package | Lacks dynamic voltage scaling and precision remote sensing; suitable only for fixed-output, non-safety-critical loads | Select when cost sensitivity outweighs need for DVS or ±2% load-point accuracy. |
| TPS6286418RRLR | 6A rated, 2.2MHz, I²C interface, but only 0.3V–1.5V output range and no spread-spectrum | Missing AEC-Q100 qualification and thermal shutdown hysteresis; limited to industrial temp range (−40°C to +105°C) | Choose for non-automotive embedded systems where EMI reduction is less critical than ultra-low quiescent current. |
Compared with MPQ4436AGL-A-Z and TPS6286418RRLR, the MAX20010CATPF/V+T uniquely combines AEC-Q100 Grade 1 qualification, differential remote sensing, spread-spectrum EMI reduction, and I²C-programmable DVS - making it the only option qualified for ASIL-B/C automotive power rails requiring both precision and robustness.

FAQ
What is the factory-preset output voltage for MAX20010CATPF/V+T?
The MAX20010CATPF/V+T does not have a factory-preset output voltage; it is a programmable variant with I²C interface enabled by default. Output voltage is set dynamically via the VID register (0x07) using 10mV or 12.5mV steps depending on VSTEP bit (0x05[7]). The device powers up to a default value determined by OTP programming - typically 0.8V unless customized per order code - but full flexibility requires I²C initialization in system firmware.
Does MAX20010CATPF/V+T support forced-PWM mode, and how is it configured?
Yes, MAX20010CATPF/V+T supports forced-PWM (FPWM) mode. It is configured either by pulling the SYNC pin high (to AV) or by setting the FPWM bit (CONFIG register 0x05[4] = 1). When FPWM = 1, the device operates continuously in PWM mode regardless of load, eliminating audible noise and improving transient response - essential for powering noise-sensitive analog circuits in automotive radar or audio subsystems.
How does the remote sensing (RS+/RS−) function in MAX20010CATPF/V+T improve regulation accuracy?
The MAX20010CATPF/V+T uses differential remote sensing (RS+/RS−) to measure output voltage directly at the load point rather than at the IC's VOUT pin. This compensates for IR drop across PCB traces and connectors, maintaining ±2% regulation accuracy at the SoC or MCU power pins - a critical requirement for automotive processors operating at sub-1V core voltages where even 20mV deviation can cause instability or timing violations.
What is the purpose of the ADDR pin on MAX20010CATPF/V+T, and how does it affect I²C communication?
The ADDR pin on MAX20010CATPF/V+T sets the LSB of the 7-bit I²C slave address. With ADDR = low, the default address is 0x38 (write 0x70, read 0x71); ADDR = high selects 0x39 (write 0x72, read 0x73). This allows up to two MAX20010CATPF/V+T devices to share the same I²C bus in multi-rail power systems - such as dual-core SoC designs - without address conflict, enabling coordinated voltage sequencing and telemetry aggregation.
Can MAX20010CATPF/V+T be used in non-automotive applications, and what derating applies?
Yes, MAX20010CATPF/V+T can be used in industrial or computing applications requiring high-current, low-noise DC-DC conversion. However, its AEC-Q100 qualification ensures reliability under harsh conditions - not performance enhancement. For non-automotive use, no electrical derating is required, but thermal design must still respect θJA = 33°C/W on a four-layer board and maximum junction temperature of +150°C. The 20-pin TQFN package remains compatible with standard SMT assembly processes.
