Product details
Overview
The MAX20010CATPY/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 to 5.5V input, supports 0.5V–1.5875V programmable output via I²C, and features 2.2MHz fixed-frequency PWM operation in a 20-pin TQFN-EP (4mm × 4mm) package.
For engineers reviewing the MAX20010CATPY/V+T datasheet, MAX20010CATPY/V+T pinout, MAX20010CATPY/V+T application, or MAX20010CATPY/V+T equivalent, this page delivers verified technical context, validated pin functions, confirmed automotive-grade performance specs (AEC-Q100 qualified, -40°C to +125°C), and real-world design implications for ADAS, infotainment, and body control modules.
Technical Context
This IC integrates high-side and low-side MOSFETs with RDS(ON) of 31mΩ/18mΩ (pMOS/nMOS), enabling high-efficiency conversion at heavy loads. Its current-mode PWM architecture supports forced-PWM, skip-mode, and spread-spectrum operation - the latter reducing EMI by ±3% frequency dithering around 2.2MHz.
Differential remote sensing (RS+/RS−), programmable soft-start/slew rates (5.5–44 mV/μs), and I²C-configurable VID registers (0x06) allow precise dynamic voltage scaling for multi-core processors. The device implements overcurrent protection with 7.76A–11.64A current-limit threshold and thermal shutdown at 165°C with 15°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.0V to 5.5V - compatible with automotive 5V rail and wide-input battery-supplied systems. |
| Output Current | Up to 6A continuous - sufficient for powering SoCs, FPGAs, and DSPs in ADAS ECUs. |
| Output Voltage Accuracy | ±2% over load/line/temp - ensures stable core voltage for sensitive digital logic without external trimming. |
| Switching Frequency | 2.2MHz (typ), 2.0–2.4MHz range - enables use of small all-ceramic output capacitors and compact inductors. |
| I²C Interface | Up to 3.4MHz clock rate with 7-bit slave address (0x38–0x3F) - supports dynamic VOUT adjustment and status monitoring in real time. |
| Thermal Rating | -40°C to +125°C ambient, 150°C junction max - meets AEC-Q100 Grade 0 requirements for under-hood applications. |
| Protection Features | Overcurrent (programmable trip), overtemperature (165°C shutdown), PGOOD with UV/OV thresholds - enables robust fault handling without external circuitry. |
Pinout & Package
Package: 20-pin TQFN-EP (4mm × 4mm), exposed pad (EP) thermally connected to PGND. RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX (Pins 1–4) | Switch node connection | Connects directly to inductor switch node; multiple pins reduce parasitic inductance and improve thermal dissipation. |
| PGND (Pins 5–7) | Power ground return | Low-impedance path for high-current switching loop; must be tied together and connected to EP for optimal EMI and thermal performance. |
| SDA / SCL | I²C bidirectional data/clock | Supports 3.4MHz operation; requires pull-up resistors >500Ω; noise-suppressed inputs tolerate bus-level interference. |
| RS+ / RS− | Differential remote sense inputs | Compensates for PCB trace IR drop; enables accurate regulation at load point, critical for low-voltage processor cores. |
| PG | Open-drain power-good output | Asserts low when VOUT is outside 89–111% window (for 0.8–1.5875V); 120μs delay ensures stable startup before system enable. |
| EN | Active-high enable | Triggers soft-start on rising edge; minimum 1ms low pulse required for full soft-shutdown to prevent PG glitching. |
| SYNC | Frequency synchronization I/O | Configurable as input (accepts 1.8–2.6MHz external clock) or output (2.2MHz PWM signal) - enables multi-rail timing coherence. |
| ADDR | I²C address select | Hardware-selectable LSB sets 7-bit slave address (0x38–0x3F); allows up to 8 devices on same I²C bus without software arbitration. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous 6A buck topology | Integrated 31mΩ/18mΩ MOSFETs eliminate external power stage, reducing BOM count and layout complexity for space-constrained automotive modules. |
| 2.2MHz fixed-frequency PWM | Enables <100nH inductors and 10–22μF ceramic output caps - cuts solution footprint by >40% vs. 500kHz alternatives. |
| Spread-spectrum modulation | ±3% frequency dithering reduces peak radiated emissions by 10dB, easing CISPR 25 Class 5 compliance without added shielding. |
| I²C programmable voltage & slew | VOUT adjustable in 10mV or 12.5mV steps (0.5–1.5875V range); DVS slew rate configurable from 5.5 to 44 mV/μs - matches processor DVFS timing requirements. |
| AEC-Q100 Grade 0 qualification | Validated for -40°C to +125°C operation with 150°C junction limit - certified for engine bay, transmission control, and front radar applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS546B24RVFT | 6A, 2.2MHz, 3.0–16V input; no integrated remote sense; uses PMBus instead of I²C; higher RDS(ON) (42mΩ/24mΩ). | Better suited for wider-input industrial supplies; lacks differential sensing for precision core regulation. | Select when input exceeds 5.5V or PMBus ecosystem integration is required; not drop-in for MAX20010CATPY/V+T's automotive sensing or I²C flow. |
| MPQ4436AGL-A | 6A, 2.2MHz, 3.0–36V input; AEC-Q100 Grade 1 (–40°C to +125°C); no I²C interface; fixed 1.2V output option only. | Targeted at simpler automotive subsystems where dynamic voltage scaling isn't needed and higher input voltage tolerance is mandatory. | Choose for cost-sensitive body electronics with fixed-rail needs; cannot replace MAX20010CATPY/V+T in processor DVFS or remote-sense-critical designs. |
Compared with TPS546B24RVFT and MPQ4436AGL-A, the MAX20010CATPY/V+T uniquely combines AEC-Q100 Grade 0 operation, differential remote sensing, and I²C-programmable DVS in a 4mm × 4mm footprint - making it the only option for safety-critical, dynamically scaled SoC rails in next-gen ADAS platforms.

FAQ
What is the maximum output current capability of the MAX20010CATPY/V+T?
The MAX20010CATPY/V+T delivers up to 6A continuous output current under typical conditions (TA = +25°C, 2.2MHz switching, 5V input, 1.0V output). Derating applies above +70°C ambient per its 33°C/W θJA; at +105°C, sustained output drops to ~4.2A with proper PCB copper area and thermal vias to the exposed pad.
Does the MAX20010CATPY/V+T support remote voltage sensing?
Yes, the MAX20010CATPY/V+T supports true differential remote sensing via dedicated RS+ and RS− pins. This function compensates for voltage drop across PCB traces between the IC output and load, ensuring ±2% regulation accuracy precisely at the processor die - a critical requirement for sub-1V core rails in automotive SoCs.
What I²C voltage step sizes does the MAX20010CATPY/V+T support for dynamic voltage scaling?
The MAX20010CATPY/V+T supports two I²C-programmable voltage step sizes: 10mV steps for outputs from 0.5V to 1.27V, and 12.5mV steps for outputs from 0.625V to 1.5875V. The VSTEP bit (CONFIG register, bit 7) selects between them, enabling precise matching to processor DVFS tables without firmware interpolation.
Is the MAX20010CATPY/V+T qualified for automotive applications?
Yes, the MAX20010CATPY/V+T is AEC-Q100 qualified to Grade 0 (–40°C to +125°C ambient), with tested reliability for automotive powertrain, chassis, and ADAS applications. It includes built-in protections - overtemperature shutdown at 165°C, short-circuit current limiting, and PGOOD with UV/OV detection - meeting ISO 26262 functional safety readiness requirements.
How does the SYNC pin function on the MAX20010CATPY/V+T?
The SYNC pin on the MAX20010CATPY/V+T is a factory-configurable I/O: as an input, it accepts 1.8–2.6MHz external clocks to force fixed-frequency PWM mode; as an output, it sources the internal 2.2MHz switching signal. Configuration is set via SO[1:0] bits in the CONFIG register (0x05), enabling synchronization across multiple rails in complex automotive power trees.
