Product details
Overview
The MAX20010DATPN/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 (10mV/12.5mV steps), and features 2.2MHz fixed-frequency PWM, spread-spectrum modulation, and differential remote sensing.
For engineers reviewing the MAX20010DATPN/V+T datasheet, MAX20010DATPN/V+T pinout, MAX20010DATPN/V+T application, or MAX20010DATPN/V+T equivalent, key selection considerations include AEC-Q100 qualification, 20-pin TQFN-EP (4mm × 4mm) package with exposed thermal pad, I²C-controlled dynamic voltage scaling, and integrated overcurrent/overtemperature protection for under-hood automotive power rails.
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 switches. Its dual-mode operation-forced-PWM at 2.2MHz (±10%) or skip mode for light-load efficiency-supports noise-sensitive automotive systems while maintaining fast load-transient response.
The device integrates differential remote sense (RS+/RS−), programmable soft-start/slew rate (5.5–44 mV/μs), and a dedicated SYNC I/O pin supporting synchronization to external clocks (1.8–2.6MHz) or daisy-chaining. Power-good (PG) output provides regulated output status with 120μs delay and configurable OV/UV thresholds.
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 supply). |
| Output Voltage Range | 0.5V to 1.5875V - Programmable in 10mV steps (0.5–1.27V) or 12.5mV steps (0.625–1.5875V) via I²C register writes. |
| Max Output Current | 6A continuous - Delivered with integrated MOSFETs; thermal design must accommodate θJA = 33°C/W on 4-layer board. |
| Voltage Accuracy | ±2% over load/line/temp - Valid for 0.8V–1.5875V outputs; tighter tolerance enables reliable core voltage regulation for ADAS SoCs. |
| Switching Frequency | 2.2MHz (typ), 2.0–2.4MHz range - Enables use of small all-ceramic output capacitors and compact PCB layout. |
| Protection Features | Overcurrent (9.7A typ trip), overtemperature (165°C shutdown), short-circuit, and PGOOD monitoring - Ensures robustness in harsh automotive environments. |
| I²C Interface | Up to 3.4MHz clock rate; 7-bit slave address configurable via ADDR pin - Enables dynamic voltage scaling for processor DVFS and system-level power sequencing. |
Pinout & Package
Package: 20-pin TQFN-EP (4mm × 4mm) with exposed thermal pad (EP), RoHS-compliant, rated for -40°C to +125°C ambient operation and qualified to AEC-Q100 Grade 1.
| 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 conduction. |
| PGND (Pins 5–7) | Power ground return | Low-impedance path for high-current switching loop; must be tied to LX-side ground plane with minimal trace length. |
| SDA / SCL (Pins 8–9) | I²C bidirectional data/clock | Supports up to 3.4MHz operation; requires external pullups (>500Ω); immune to bus noise via internal spike suppression. |
| RS+ / RS− (Pins 10–11) | Differential remote sense inputs | Compensates for IR drop across PCB traces; enables precise regulation at load point rather than at IC output pins. |
| PG (Pin 12) | Open-drain power-good indicator | Asserts low when VOUT is outside 89–111% window (for ≥0.8V); includes 120μs blanking after regulation achieved. |
| EN (Pin 13) | Active-high enable | Triggers soft-start on rising edge; initiates controlled 5.5mV/μs shutdown ramp when pulled low for ≥1ms. |
| SYNC (Pin 14) | Frequency sync I/O | Configurable as input (accepts 1.8–2.6MHz external clock) or output (2.2MHz PWM signal) for multi-rail synchronization. |
| GND (Pin 15) | Analog ground reference | Separate from PGND to minimize noise coupling into feedback and control circuits; connects to analog ground plane. |
| AV (Pin 16) | Analog supply input | Filtered via 100Ω resistor + 1μF ceramic cap to GND; powers internal reference and error amplifier for stable regulation. |
| ADDR (Pin 17) | I²C address select | Configures LSB of 7-bit slave address (0x38–0x3F); allows up to 8 devices on same I²C bus without address conflict. |
| PV (Pins 18–20) | Main power input | Accepts 3.0–5.5V; requires ≥4.7μF ceramic capacitor to PGND per pin; multiple pins reduce ESR and improve decoupling. |
| EP | Exposed thermal pad | Must be soldered to solid ground plane for thermal management; contributes significantly to θJC = 2°C/W performance. |

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 max output, 2.2MHz fixed frequency, no I²C interface, no remote sensing, QFN-13 package | Suitable for cost-sensitive non-automotive applications where dynamic voltage scaling and precision remote sensing are not required | Select if I²C control and ±2% remote-regulated accuracy are unnecessary and 4A output suffices. |

FAQ
What is the maximum output current capability of the MAX20010DATPN/V+T?
The MAX20010DATPN/V+T delivers up to 6A continuous output current with integrated high-side and low-side MOSFETs. This rating assumes proper thermal management using the exposed pad (EP) soldered to a solid ground plane and operation within the -40°C to +125°C ambient temperature range. Peak current-limit threshold is 9.7A typical, with automatic hiccup-mode recovery during overload.
Does the MAX20010DATPN/V+T support dynamic voltage scaling via I²C?
Yes, the MAX20010DATPN/V+T supports full dynamic voltage scaling through its I²C interface. Output voltage can be programmed from 0.5V to 1.27V in 10mV steps or from 0.625V to 1.5875V in 12.5mV steps using the VID register (0x06). Slew rate is independently configurable (5.5–44 mV/μs) via the SLEW register (0x05) to ensure glitch-free transitions.
Is the MAX20010DATPN/V+T qualified for automotive applications?
Yes, the MAX20010DATPN/V+T is AEC-Q100 qualified (Grade 1) for operation from -40°C to +125°C ambient temperature. It includes automotive-specific protections such as overtemperature shutdown (165°C), short-circuit recovery, and robust EMI mitigation via 2.2MHz switching and spread-spectrum modulation-making it suitable for under-hood and cabin ADAS and infotainment systems.
What package type and thermal characteristics does the MAX20010DATPN/V+T use?
The MAX20010DATPN/V+T uses a 20-pin TQFN-EP package measuring 4mm × 4mm with an exposed thermal pad (EP). Its thermal resistance is θJA = 33°C/W on a standard four-layer PCB and θJC = 2°C/W to the exposed pad. Proper soldering of the EP to a large copper ground plane is essential to achieve rated 6A performance and maintain junction temperature below 150°C.
How does the MAX20010DATPN/V+T handle power-good signaling and fault detection?
The MAX20010DATPN/V+T provides an open-drain PGOOD (PG) output that asserts low when VOUT falls outside the configured OV/UV window (e.g., 89–111% for 0.8V+ outputs) and remains low for 120μs after regulation is achieved. Faults-including overvoltage, undervoltage, overcurrent, and thermal shutdown-are also reported via the STATUS register (0x03), accessible over I²C for system-level diagnostics.
