Product details
Overview
MAX20010CATPU/V+ from Analog Devices is a high-efficiency, synchronous 6A step-down DC-DC converter for automotive point-of-load regulation. It operates from 3.0V to 5.5V input, delivers 0.5V–1.5875V output with ±2% accuracy over load/line/temperature, features 2.2MHz fixed-frequency PWM, I²C-controlled dynamic voltage scaling, and AEC-Q100 Grade 1 qualification (−40°C to +125°C).
For engineers reviewing the MAX20010CATPU/V+ datasheet, MAX20010CATPU/V+ pinout, MAX20010CATPU/V+ application, or MAX20010CATPU/V+ equivalent, key selection criteria include its integrated 6A power stage, differential remote sensing, programmable soft-start/slew rate, spread-spectrum EMI reduction, and robust automotive protections including PGOOD, overcurrent, and thermal shutdown.
Technical Context
The MAX20010CATPU/V+ implements current-mode control with forced-PWM and skip-mode operation, enabling stable regulation under transient loads while optimizing light-load efficiency. Its 2.2MHz switching frequency supports all-ceramic output filtering and compact PCB layout.
Internal architecture integrates low-RDS(ON) pMOS (31mΩ typ) and nMOS (18mΩ typ) switches, a 7-bit DAC for I²C voltage programming, and configurable SYNC I/O for system clock synchronization or spread-spectrum modulation. The device uses differential remote sense (RS+/RS−) to compensate for PCB IR drop and maintain tight output regulation at the load.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
MAX20010CATPU/V+ is housed in a 20-pin TQFN-EP package (4mm × 4mm, 0.5mm pitch) with exposed thermal pad. This RoHS-compliant package provides low θJA = 33°C/W on a 4-layer board and supports high-power dissipation in space-constrained automotive modules.
| 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 in high-6A operation. |
| PGND (Pins 5–7) | Power ground return | Low-impedance path for high di/dt currents; must be tied to LX-side ground plane and thermally connected to EP. |
| SDA / SCL | I²C bidirectional data/clock | Supports up to 3.4MHz I²C for dynamic voltage scaling; requires external pullups ≥500Ω. |
| RS+ / RS− | Differential remote sense inputs | Enables precise regulation at load by rejecting PCB trace resistance; improves accuracy beyond local feedback. |
| PG | Open-drain power-good output | Asserts low after 120μs when VOUT enters regulation window; requires external pullup for logic-level interface. |
| EN | Active-high enable | Initiates soft-start on rising edge; minimum 1ms low pulse required for complete soft-shutdown sequence. |
| SYNC | 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. |
| ADDR | I²C address select | Configures 7-bit slave address (default 0x38 write); allows up to 8 devices on same I²C bus. |
| EP | Exposed thermal pad | Mandatory solder connection to GND plane; primary heat dissipation path-does not replace PGND/GND connections. |
Key Features
| Feature | Design Value |

FAQ
What is the maximum output current capability of the MAX20010CATPU/V+?
The MAX20010CATPU/V+ delivers up to 6A continuous output current under typical conditions (TA ≤ +85°C, 4-layer board). At +125°C ambient, derating applies per thermal limits-junction temperature must remain ≤ +150°C. The device includes cycle-by-cycle overcurrent protection triggered at ~9.7A (typ), ensuring safe operation during short-circuit events without external current-sense components.
Does the MAX20010CATPU/V+ support dynamic voltage scaling (DVS) via I²C?
Yes, the MAX20010CATPU/V+ supports full dynamic voltage scaling via its standard 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 (0x07). Slew rate is independently configurable (5.5–44 mV/μs) via the SLEW register (0x05), enabling controlled transitions between performance and low-power states in automotive SoCs.
What is the purpose of the RS+ and RS− pins on the MAX20010CATPU/V+?
The RS+ and RS− pins implement differential remote voltage sensing on the MAX20010CATPU/V+. They connect directly to the load-side power and ground planes, allowing the IC to regulate output voltage precisely at the point-of-load-compensating for IR drop across PCB traces and connectors. This maintains ±2% accuracy even with >50mV trace resistance, which is essential for stable operation of sensitive automotive processors and MMICs.
How does the MAX20010CATPU/V+ handle electromagnetic interference (EMI) in automotive environments?
The MAX20010CATPU/V+ reduces EMI through three integrated features: (1) 2.2MHz fixed-frequency operation minimizes energy in the AM radio band; (2) programmable spread-spectrum modulation (±3%) spreads spectral energy to lower peak emissions; and (3) SYNC I/O enables synchronization of multiple converters to avoid beat frequencies. These features collectively help meet stringent CISPR 25 Class 5 radiated emissions limits without external shielding or complex filtering.
Is the MAX20010CATPU/V+ qualified for automotive applications?
Yes, the MAX20010CATPU/V+ is AEC-Q100 qualified for Grade 1 operation (−40°C to +125°C ambient temperature). It includes automotive-specific protections: open-drain PGOOD with UV/OV detection, thermal shutdown at +165°C with 15°C hysteresis, cycle-by-cycle overcurrent limiting, and robust ESD tolerance (HBM ≥2kV). Its TQFN-EP package and internal low-RDS(ON) switches ensure reliability in harsh automotive environments including engine compartments and ADAS sensor housings.
