Product details
Overview
The MAX20010CATPD/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 across load, line, and temperature. It operates from 3.0V to 5.5V input and supports programmable output voltages from 0.5V to 1.5875V via I²C, features 2.2MHz fixed-frequency PWM operation, spread-spectrum modulation, and AEC-Q100 qualification.
For engineers reviewing the MAX20010CATPD/V+ datasheet, MAX20010CATPD/V+ pinout, MAX20010CATPD/V+ application, or MAX20010CATPD/V+ equivalent, key selection considerations include its 20-pin TQFN-EP package with exposed pad, differential remote sensing capability, I²C-controlled dynamic voltage scaling (DVS) with 10mV/12.5mV step resolution, and integrated overtemperature/overcurrent protection for harsh automotive environments.
Technical Context
This IC implements current-mode control with forced-PWM, skip-mode, and frequency-synchronization I/O to optimize noise immunity and light-load efficiency. Its internal architecture integrates low-RDS(ON) pMOS (31–55mΩ) and nMOS (18–31mΩ) power switches, enabling high-efficiency conversion without external MOSFETs.
The device uses a 7-bit VID register with programmable slew rates (5.5–44 mV/μs), configurable spread-spectrum (±3%), and FPWM mode override - all accessible via I²C interface operating up to 3.4MHz. The PGOOD output provides regulated voltage monitoring with 89–95% UV and 105–111% OV thresholds depending on VOUT range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.0V to 5.5V - supports direct connection to automotive battery rails with transient tolerance up to +6V on PV/AV pins. |
| Output Voltage Range | 0.5V to 1.5875V - factory-preset or I²C-programmable in 10mV or 12.5mV steps for processor core rail flexibility. |
| Max Output Current | 6A continuous - enabled by integrated 31mΩ pMOS and 18mΩ nMOS switches, eliminating need for external power FETs. |
| Switching Frequency | 2.2MHz (±10%) - enables use of small all-ceramic capacitors and compact PCB layout with minimal EMI filtering. |
| Output Accuracy | ±2% over load/line/temp - ensures stable supply to sensitive automotive SoCs and MCUs without external trimming. |
| Thermal Rating | -40°C to +125°C ambient - qualified per AEC-Q100 Grade 0, with thermal shutdown at 165°C and 15°C hysteresis. |
| I²C Interface | Up to 3.4MHz - supports dynamic voltage scaling (DVS), soft-start rate control, and real-time status register reads (e.g., OC, UV, OV flags). |
Pinout & Package
MAX20010CATPD/V+ is housed in a 20-pin, 4mm × 4mm thermally enhanced TQFN-EP package (package code T2044+4C) with an exposed pad soldered to PCB ground for optimal thermal dissipation (θJA = 33°C/W on 4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX (Pins 1–4) | Switch node connection | Drives external inductor; all four pins must be shorted together to minimize parasitic inductance and switching losses. |
| PGND (Pins 5–7) | Power ground return | Low-impedance path for high-current switch node return; separate from analog ground to reduce noise coupling. |
| SDA / SCL (Pins 8–9) | I²C bidirectional data/clock | Enable dynamic voltage adjustment, fault monitoring, and configuration; require ≥500Ω pull-up resistors. |
| RS+/RS- (Pins 10–11) | Differential remote sense inputs | Compensate for PCB trace IR drop to maintain ±2% regulation accuracy at load point, not at IC pins. |
| PG (Pin 12) | Open-drain power-good flag | Asserts low when VOUT is outside 89–95% UV / 105–111% OV 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 full soft-shutdown sequence completion. |
| SYNC (Pin 14) | Frequency sync I/O | Configurable as input (accepts 1.8–2.6MHz clock) or output (2.2MHz PWM signal) to synchronize multiple converters. |
| GND (Pin 15) | Analog ground reference | Isolated ground for internal error amplifier and reference circuitry; must be connected separately from PGND. |
| AV (Pin 16) | Analog supply input | Filtered via 100Ω resistor + 1μF ceramic cap to GND; powers precision internal reference and control circuits. |
| ADDR (Pin 17) | I²C address select | Sets 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 input; each pin connects to bulk capacitance (≥4.7μF ceramic) to suppress high-frequency ripple. |
| EP | Exposed thermal pad | Must be soldered to solid PCB ground plane; provides primary thermal path (θJC = 2°C/W) but does not replace PGND/GND connections. |
Key Features
| Feature | Design Value |

| Integrated 6A power stage | Eliminates discrete MOSFETs and gate drivers, reducing BOM count and layout complexity while improving thermal performance. |
| Differential remote sensing | Maintains ±2% output regulation accuracy at the load point despite PCB trace resistance, critical for high-current automotive SoC rails. |
| I²C programmable DVS | Enables real-time voltage scaling (e.g., CPU DVFS) with user-defined slew rates (5.5–44 mV/μs) to balance power savings vs. transient response. |

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 |
|---|---|---|---|
| MPQ4436GL-A | 4A rated, 2.2MHz, no I²C interface, no spread-spectrum, smaller 3mm × 4mm QFN | Lacks dynamic voltage scaling and EMI reduction features; suitable only for fixed-output, cost-sensitive non-automotive designs | Select only if I²C control, AEC-Q100 qualification, or ±2% accuracy over temperature are not required. |
| TPS6286418RTER | 6A rated, 2.25MHz, I²C interface, but no remote sensing, lower temp rating (-40°C to +105°C), not AEC-Q100 qualified | Targeted at industrial computing, not automotive; lacks differential sensing and extended temperature support | Consider only for non-automotive applications where remote sensing and Grade 0 qualification are unnecessary. |

FAQ
What is the maximum output current capability of the MAX20010CATPD/V+?
The MAX20010CATPD/V+ delivers up to 6A continuous output current using its integrated high-side and low-side MOSFETs. This is achieved with typical RDS(ON) values of 31mΩ (pMOS) and 18mΩ (nMOS) at 5V input, enabling high-efficiency conversion without external power switches. The device sustains this current across its full operating temperature range of -40°C to +125°C ambient.
Does the MAX20010CATPD/V+ support dynamic voltage scaling (DVS) via I²C?
Yes, the MAX20010CATPD/V+ supports full dynamic voltage scaling via its standard-compliant I²C interface. It allows real-time adjustment of the output voltage between 0.5V and 1.27V in 10mV steps or 0.625V to 1.5875V in 12.5mV steps using the 7-bit VID register. Slew rate is independently programmable (5.5–44 mV/μs) via the SLEW register to match processor DVFS timing requirements.
What package type and thermal characteristics does the MAX20010CATPD/V+ use?
The MAX20010CATPD/V+ uses a 20-pin, 4mm × 4mm TQFN-EP package with exposed pad (T2044+4C). Its thermal resistance is θJA = 33°C/W on a standard 4-layer PCB and θJC = 2°C/W to the exposed pad. The pad must be soldered to a solid ground plane to achieve rated performance and ensure safe operation at 6A continuous load in automotive under-hood environments.
How does the MAX20010CATPD/V+ handle overcurrent and short-circuit conditions?
Under overcurrent or short-circuit conditions, the MAX20010CATPD/V+ enters hiccup mode: it shuts down for 4ms (at 2.2MHz switching frequency), then restarts soft-start. This cycle repeats until the fault clears. The STATUS register (bit OC) flags overcurrent events, and the current-limit threshold is factory-trimmed to 7.76–11.64A. Differential remote sensing ensures accurate current detection independent of PCB layout.
Is the MAX20010CATPD/V+ qualified for automotive applications?
Yes, the MAX20010CATPD/V+ is AEC-Q100 qualified Grade 0 (−40°C to +125°C ambient), with built-in protections including overtemperature shutdown at 165°C (15°C hysteresis), open-drain PGOOD monitoring, and robust ESD ratings. It meets automotive EMC requirements via 2.2MHz switching, spread-spectrum modulation, and frequency synchronization - all validated per ISO 11452 and CISPR 25 standards.
