Product details
Overview
The MAX20010DATPY/V+ 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 over 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 with spread-spectrum modulation for EMI reduction.
For engineers reviewing the MAX20010DATPY/V+ datasheet, MAX20010DATPY/V+ pinout, MAX20010DATPY/V+ application, or MAX20010DATPY/V+ equivalent, key selection criteria include its AEC-Q100 qualification, differential remote sensing capability, I²C-controlled dynamic voltage scaling (DVS) with 10mV/12.5mV step resolution, forced-PWM/skip-mode flexibility, and integrated overcurrent/overtemperature protection in a thermally enhanced 20-pin TQFN package.
Technical Context
This IC implements current-mode control with integrated high-side (31mΩ typ) and low-side (18mΩ typ) MOSFETs, enabling efficient 6A operation without external power switches. Its 2.2MHz switching frequency allows full-ceramic capacitor designs and minimizes solution footprint while maintaining robust transient response-enhanced in the MAX20010D variant over the base C version.
The device integrates a 7-bit VID DAC, programmable soft-start/slew rates (5.5–44 mV/μs), and configurable SYNC I/O supporting both master (external clock synchronization) and slave (frequency output) modes. The I²C interface (up to 3.4MHz) enables real-time voltage adjustment, status monitoring (OV/UV/OC/thermal flags), and configuration of spread-spectrum, FPWM mode, and voltage step size.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.0V to 5.5V - supports direct connection to automotive battery rail (with transient tolerance up to 6V absolute max). |
| Output Current | Up to 6A continuous - sufficient for powering modern automotive SoCs, FPGAs, and DSPs at sub-1.2V core voltages. |
| Output Voltage Accuracy | ±2% over load, line, and temperature - ensures stable core supply under varying thermal and loading conditions. |
| Switching Frequency | 2.2MHz (typ), ±200kHz - enables compact magnetics and all-ceramic output filtering; supports external sync from 1.8MHz to 2.6MHz. |
| I²C Interface | 3.4MHz Fast Mode - allows rapid DVS updates and real-time fault register reads without system interruption. |
| Thermal Protection | 165°C shutdown with 15°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
| Package | 20-pin TQFN-EP (4mm × 4mm, 0.5mm pitch) - exposed pad provides low θJC = 2°C/W for reliable 6A operation in -40°C to +125°C ambient. |
Pinout & Package
MAX20010DATPY/V+ uses 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 functions 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 | Connects directly to inductor switch node; multiple pins reduce parasitic inductance and improve current sharing at 6A. |
| PGND (Pins 5–7) | Power ground return | Dedicated low-impedance path for high di/dt currents; must be tied to EP and local ceramic input cap ground. |
| SDA / SCL (Pins 8–9) | I²C bidirectional data/clock | Supports 3.4MHz communication; requires pull-up resistors >500Ω; immune to bus noise via internal spike suppression. |
| RS+/RS- (Pins 10–11) | Differential remote sense inputs | Compensates for PCB trace IR drop to maintain ±2% regulation at load point, critical for low-voltage cores. |
| PG (Pin 12) | Open-drain power-good flag | Asserts low for 120μs after VOUT enters regulation window; requires external pull-up for logic-level signaling. |
| EN (Pin 13) | Active-high enable | Triggers soft-start on rising edge; initiates controlled 5.5mV/μs shutdown ramp when pulled low. |
| SYNC (Pin 14) | Configurable sync I/O | Factory-set as input or output; accepts 1.8–2.6MHz external clocks or outputs internal 2.2MHz for multi-rail synchronization. |
| GND (Pin 15) | Analog ground reference | Separate from PGND to minimize noise coupling into error amplifier and reference circuitry. |
| AV (Pin 16) | Analog supply filter node | Requires RC filter (100Ω + 1μF) from PV to reject switching noise from analog bias circuits. |
| ADDR (Pin 17) | I²C address select | Configures 7-bit slave address (0x38–0x3F); enables multiple devices on same bus without address conflict. |
| PV (Pins 18–20) | Main power input | Accepts 3.0–5.5V; requires ≥4.7μF ceramic cap per pin; multiple pins reduce impedance and improve decoupling. |

FAQ
What is the maximum output current capability of the MAX20010DATPY/V+?
The MAX20010DATPY/V+ delivers up to 6A continuous output current under specified thermal conditions (TA ≤ +70°C, proper PCB copper pour and EP grounding). Its integrated 31mΩ high-side and 18mΩ low-side MOSFETs enable this rating without external switches, and thermal shutdown at 165°C protects against sustained overload. Derating applies above +70°C ambient per the 33°C/W θJA specification.
Does the MAX20010DATPY/V+ support dynamic voltage scaling (DVS) via I²C?
Yes, the MAX20010DATPY/V+ supports full dynamic voltage scaling via its I²C interface. Using the 7-bit VID register (0x07), output voltage can be adjusted in real time between 0.5V–1.27V (10mV steps) or 0.625V–1.5875V (12.5mV steps). Slew rate is independently programmable (5.5–44 mV/μs) via the SLEW register (0x05), enabling controlled transitions during processor frequency changes.
How does the MAX20010DATPY/V+ achieve ±2% output voltage accuracy?
The MAX20010DATPY/V+ achieves ±2% output voltage accuracy through a combination of high-precision internal voltage reference, differential remote sensing (RS+/RS−), and tight feedback loop compensation. The ±2% spec holds across full load (0–6A), input (3.0–5.5V), and temperature (-40°C to +125°C) ranges. Differential sensing compensates for PCB trace resistance, ensuring regulation accuracy is maintained at the load point-not just at the IC's VOUT pin.
What is the purpose of the SYNC pin on the MAX20010DATPY/V+?
The SYNC pin on the MAX20010DATPY/V+ is a factory-configurable I/O that supports two modes: as an input to synchronize switching frequency to an external 1.8–2.6MHz clock (enabling multi-rail phase alignment), or as an output to drive other compatible converters' SYNC inputs. This eliminates beat frequencies and reduces system-level EMI, especially critical in dense automotive PCB layouts with multiple switching regulators.
Is the MAX20010DATPY/V+ qualified for automotive applications?
Yes, the MAX20010DATPY/V+ is AEC-Q100 Grade-1 qualified, meaning it is tested and certified for operation from -40°C to +125°C junction temperature and meets rigorous automotive reliability standards including HTOL, TC, UHAST, and ESD testing. Its design includes automotive-specific protections such as short-circuit recovery, thermal shutdown with hysteresis, and robust EMI mitigation-making it suitable for ADAS, infotainment, and body control modules.
