Product details
Overview
MAX20010CATPY/V+ 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 interface, and features 2.2MHz fixed-frequency PWM operation with spread-spectrum modulation for automotive point-of-load regulation.
For engineers reviewing the MAX20010CATPY/V+ datasheet, MAX20010CATPY/V+ pinout, MAX20010CATPY/V+ application, or MAX20010CATPY/V+ equivalent, key selection considerations include its 20-pin TQFN-EP (4mm × 4mm) package, differential remote sensing capability, I²C-controlled dynamic voltage scaling (DVS), integrated pMOS/nMOS switches (RDS(ON) = 31/18 mΩ typ), and robust automotive-grade protections including overtemperature shutdown (165°C), overcurrent limiting (9.7A typ), and PGOOD monitoring.
Technical Context
The MAX20010CATPY/V+ implements current-mode control with forced-PWM, skip-mode, and frequency-synchronization capabilities. Its internal 7-bit DAC enables precise VID-based output voltage setting, while configurable soft-start and DVS slew rates (5.5–44 mV/μs) support controlled power sequencing in multi-rail automotive systems.
It integrates dual low-RDS(ON) MOSFETs, differential remote sense inputs (RS+/RS−), and a dedicated analog supply (AV) with separate PGND/GND planes to minimize noise coupling. The SYNC pin functions as bidirectional I/O-configurable as master clock input (1.8–2.6MHz) or PWM frequency output-enabling system-level timing coordination across multiple converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.0V to 5.5V - Supports direct connection to automotive battery rail (e.g., 3.3V/5V post-LDO or 12V buck-derived supplies). |
| Output Current | Up to 6A continuous - Enables single-chip power delivery for high-performance ADAS SoCs or microcontrollers without external MOSFETs. |
| Output Voltage Accuracy | ±2% over load/line/temp - Ensures stable core voltage for processors requiring tight regulation (e.g., 0.95V ±19mV at full load). |
| Switching Frequency | 2.2MHz (typ), ±3% spread-spectrum - Allows use of small all-ceramic output capacitors and reduces EMI peak emissions. |
| I²C Interface | 3.4MHz max clock, 7-bit slave address (0x38–0x3F) - Enables real-time DVS, fault register readback, and configuration updates without interrupting operation. |
| Thermal Protection | 165°C shutdown with 15°C hysteresis - Prevents thermal runaway during sustained overload or poor PCB heatsinking. |
| Package | 20-pin TQFN-EP (4mm × 4mm, 0.5mm pitch) - Exposed pad enhances thermal performance (θJA = 33°C/W on 4-layer board) for under-hood applications. |
Pinout & Package
MAX20010CATPY/V+ is housed in a 20-pin thermally enhanced thin quad flat no-lead (TQFN-EP) package measuring 4mm × 4mm with 0.5mm pitch and an exposed thermal pad (EP) that must be soldered to a PCB ground plane for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–4, 18–20 (LX, PV) | Power switch node / Input supply | LX pins connect to inductor switch node; PV pins accept 3.0–5.5V input with local 4.7µF ceramic decoupling to PGND. |
| 5–7, EP (PGND) | Power ground return | Low-impedance path for high-current switching loops; EP must be connected to system ground for thermal dissipation. |
| 8–9 (SDA, SCL) | I²C serial interface | Supports up to 3.4MHz communication for VID programming, status monitoring, and configuration registers (e.g., CONFIG, STATUS). |
| 10–11 (RS−, RS+) | Differential remote sense inputs | Enable accurate load-point regulation by compensating for PCB trace IR drop; require Kelvin connection to VOUT. |
| 12 (PG) | Open-drain power-good indicator | Asserts low for 120µs after VOUT enters regulation window; requires external pull-up to logic supply (e.g., 3.3V). |
| 13 (EN) | Active-high enable | Initiates soft-start on rising edge; minimum 1ms low pulse ensures complete soft-shutdown before re-enable. |
| 14 (SYNC) | Frequency synchronization I/O | Configurable as input (accepts 1.8–2.6MHz clock) or output (2.2MHz PWM signal) to align switching across multiple rails. |
| 15 (GND) | Analog ground reference | Separate AGND plane minimizes noise coupling into sensitive feedback and reference circuits. |
| 16 (AV) | Analog supply input | Filtered via 100Ω resistor + 1µF ceramic cap to GND; powers internal reference and error amplifier for precision regulation. |
| 17 (ADDR) | I²C address select | Configures LSB of 7-bit slave address (default 0x38); allows up to 8 devices on same I²C bus. |

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 |
|---|---|---|---|
| TPS62933RGER (Texas Instruments) | 3.0–5.5V input, 6A output, 2.2MHz, but lacks differential remote sensing and I²C interface; uses PMBus v1.3. | Targeted at industrial/commercial systems where AEC-Q100 is not required and remote sensing is unnecessary. | Select when PMBus compatibility and TI's WEBENCH support are prioritized over automotive qualification and fine-grained DVS control. |
| MPQ4482GR-A (Monolithic Power Systems) | 3.0–5.5V input, 6A output, 2.2MHz, AEC-Q100 Grade 1, but only supports pin-strapped fixed output (no I²C) and no spread-spectrum. | Suitable for cost-sensitive automotive modules with static voltage requirements (e.g., memory rails). | Choose when I²C programmability and EMI reduction are non-critical, and fixed-output simplicity is preferred. |
Compared with TPS62933RGER and MPQ4482GR-A, the MAX20010CATPY/V+ uniquely combines AEC-Q100 qualification, differential remote sensing, I²C-based DVS, and spread-spectrum EMI reduction in a single 4mm × 4mm package-making it optimal for safety-critical, dynamically scaled automotive SoC rails.

FAQ
What is the factory-preset output voltage for MAX20010CATPY/V+?
The MAX20010CATPY/V+ does not have a factory-preset output voltage; it is a fully I²C-programmable device supporting dynamic voltage adjustment from 0.5V to 1.5875V in either 10mV or 12.5mV steps. Output voltage is set via the VID register (0x07) and enabled by configuring the VSTEP bit (CONFIG register, 0x05). This allows flexible integration into systems requiring runtime voltage scaling without hardware changes.
Does MAX20010CATPY/V+ support synchronization with external clock sources?
Yes, MAX20010CATPY/V+ supports external clock synchronization via its bidirectional SYNC pin. When configured as an input (SO[1:0] = 00 or 01), it accepts external clocks from 1.8MHz to 2.6MHz to force fixed-frequency PWM operation. When configured as an output (SO[1:0] = 10), it outputs the internal 2.2MHz switching frequency, enabling precise phase alignment across multiple MAX20010 devices in multi-rail automotive systems.
How does the differential remote sensing (RS+/RS−) function in MAX20010CATPY/V+?
In MAX20010CATPY/V+, the RS+ and RS− pins form a Kelvin sense pair that monitors output voltage directly at the load, rejecting voltage drop across PCB traces. The internal error amplifier compares this remote measurement to the internal reference, adjusting duty cycle to maintain ±2% regulation at the load-not at the IC's VOUT pin. This requires separate routing of RS+ and RS− traces away from power paths to preserve accuracy.
What protection features are integrated into MAX20010CATPY/V+?
MAX20010CATPY/V+ integrates overtemperature shutdown (165°C, 15°C hysteresis), cycle-by-cycle overcurrent limiting (9.7A typical), short-circuit protection with auto-retry, input undervoltage lockout (2.85V rising), open-drain PGOOD with timeout, and I²C-accessible fault registers (STATUS register, 0x03). These features ensure safe operation during battery transients, thermal overload, or load faults in automotive environments.
Is MAX20010CATPY/V+ compatible with standard I²C buses operating at 100kHz or 400kHz?
Yes, MAX20010CATPY/V+ supports standard-mode (100kHz) and fast-mode (400kHz) I²C, as well as fast-mode plus (1MHz) and high-speed mode (3.4MHz). Its SDA/SCL inputs meet I²C specification thresholds (VIH = 1.3V min, VIL = 0.5V max) and include spike suppression (20ns), making it interoperable with legacy microcontrollers and modern automotive SoCs without level-shifting or protocol adaptation.
