Product details
Overview
The MAX20010CATPJ/V+T from Analog Devices is a high-efficiency, synchronous 6A step-down DC-DC converter for automotive point-of-load regulation, operating from 3.0V to 5.5V input and delivering 0.5V–1.5875V output with ±2% accuracy over load, line, and temperature. It features 2.2MHz fixed-frequency PWM, I²C-controlled dynamic voltage scaling (10mV/12.5mV steps), differential remote sensing, and AEC-Q100 Grade 0 qualification (−40°C to +125°C).
For engineers reviewing the MAX20010CATPJ/V+T datasheet, MAX20010CATPJ/V+T pinout, MAX20010CATPJ/V+T application, or MAX20010CATPJ/V+T equivalent, key selection criteria include its integrated 31mΩ/18mΩ MOSFETs, programmable soft-start and slew rate, spread-spectrum EMI reduction, PGOOD monitoring, and SYNC I/O for system clock synchronization in ADAS and infotainment power rails.
Technical Context
This IC implements current-mode control with forced-PWM, skip-mode, and frequency-synchronization capability. Its internal block includes a 7-bit DAC for VID-based voltage setting, peak-current-limit protection (7.76A–11.64A), thermal shutdown at 165°C with 15°C hysteresis, and dual-mode I²C interface supporting up to 3.4MHz clock rate and configurable slave address via ADDR pin.
The device uses differential remote sensing (RS+/RS−) for precise load-point regulation and integrates low-RDS(ON) switches to minimize conduction loss. Its 20-pin TQFN-EP (4mm × 4mm) package with exposed pad enables efficient thermal dissipation (θJA = 33°C/W on 4-layer board), critical for sustained 6A operation in compact automotive modules.

Pinout & Package
Package: 20-pin TQFN-EP (4mm × 4mm, outline 21-100172), exposed thermal pad (EP) soldered to PCB ground plane for optimal heat transfer (θJC = 2°C/W).
| 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 current sharing |
| PGND (Pins 5–7) | Power ground return | Low-impedance path for high di/dt switching currents; must be tied to EP and local ceramic capacitor ground |
| SDA / SCL (Pins 8–9) | I²C bidirectional data/clock | Supports dynamic voltage adjustment and status readback; requires ≥500Ω pull-up resistors |
| RS+/RS− (Pins 10–11) | Differential remote sense inputs | Compensates for PCB trace IR drop to maintain ±2% regulation at load point |
| PG (Pin 12) | Open-drain power-good flag | Asserts after 120μs when 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 |
| SYNC (Pin 14) | Frequency sync I/O | Configurable as input (1.8–2.6MHz external clock) or output (2.2MHz PWM clock) for multi-rail synchronization |
| GND (Pin 15) | Analog ground reference | Separate from PGND to isolate noise-sensitive analog circuits (EAMP, reference, DAC) |
| AV (Pin 16) | Analog supply filter input | Must be decoupled with 100Ω resistor + 1μF ceramic cap to GND for clean internal reference |
| ADDR (Pin 17) | I²C address select | Configures LSB of 7-bit slave address (0x38–0x3F); sets default VID and FPWM/SS modes per ordering option |
| PV (Pins 18–20) | Main power input | Accepts 3.0–5.5V; requires ≥4.7μF ceramic cap to PGND; multiple pins reduce impedance and ESR |
Key Features

FAQ
What is the maximum output current capability of the MAX20010CATPJ/V+T?
The MAX20010CATPJ/V+T delivers up to 6A continuous output current under specified thermal conditions (TA ≤ +125°C, proper PCB layout with EP grounded). This rating assumes use of recommended external components-including a 0.47µH inductor and ≥22µF total output capacitance-and accounts for internal MOSFET RDS(ON) (31mΩ pMOS / 18mΩ nMOS) and thermal resistance (θJA = 33°C/W).
Does the MAX20010CATPJ/V+T support dynamic voltage scaling via I²C?
Yes, the MAX20010CATPJ/V+T supports full dynamic voltage scaling through its standard I²C interface. The output voltage can be adjusted in real time between 0.5V and 1.27V in 10mV steps, or between 0.625V and 1.5875V in 12.5mV steps, using the VID register (0x07) and VSTEP bit (CONFIG register, 0x05). Slew rate is independently programmable from 5.5 to 44 mV/μs.
What is the purpose of the RS+ and RS− pins on the MAX20010CATPJ/V+T?
The RS+ and RS− pins on the MAX20010CATPJ/V+T provide differential remote voltage sensing to compensate for IR drop across PCB traces between the regulator and load. By measuring feedback directly at the load, the MAX20010CATPJ/V+T maintains ±2% output accuracy even with >100mV voltage drop-critical for high-current, low-voltage SoC rails where trace resistance significantly impacts regulation.
How does the SYNC pin function on the MAX20010CATPJ/V+T?
The SYNC pin on the MAX20010CATPJ/V+T is a factory-configurable I/O that operates either as an input (accepting 1.8–2.6MHz external clock for forced-PWM mode) or as an output (delivering the internal 2.2MHz PWM clock). Configuration is set via SO[1:0] bits in the CONFIG register (0x05) and determines whether the device synchronizes to a system master clock or drives other synchronized regulators in multi-rail designs.
Is the MAX20010CATPJ/V+T qualified for automotive applications?
Yes, the MAX20010CATPJ/V+T is AEC-Q100 qualified to Grade 0 (−40°C to +125°C ambient operating temperature), with built-in protections including overtemperature shutdown (165°C), overcurrent limiting, undervoltage lockout (2.85V rising), and open-drain PGOOD output. It meets stringent automotive reliability, EMI, and functional safety requirements for ADAS, radar, and domain controller power systems.
