Product details
Overview
The MAX20010CATPJ/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–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 Grade 1 qualification (−40°C to +125°C).
For engineers reviewing the MAX20010CATPJ/V+ datasheet, MAX20010CATPJ/V+ pinout, MAX20010CATPJ/V+ application, or MAX20010CATPJ/V+ equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade thermal and protection features, and real-world design implications of its I²C-controlled DVS, remote sensing, and forced-PWM/skip-mode operation.
Technical Context
The MAX20010CATPJ/V+ implements a current-mode, synchronous buck architecture with integrated high-side (31mΩ typical) and low-side (18mΩ typical) MOSFETs, enabling high-efficiency conversion at full 6A load. Its 2.2MHz switching frequency supports all-ceramic output filtering and minimizes solution footprint while maintaining robust transient response - enhanced in the MAX20010D/E variants, though the CATPJ/V+ variant retains the base C-series performance profile.
It integrates differential remote voltage sensing (RS+/RS−), programmable soft-start/slew rates (5.5–44 mV/μs), overcurrent protection with 7.76A–11.64A current-limit threshold, and thermal shutdown at 165°C with 15°C hysteresis. The I²C interface (up to 3.4MHz) enables dynamic voltage scaling with 10mV or 12.5mV resolution, controlled via VID register writes and VSTEP configuration bit.

Pinout & Package
MAX20010CATPJ/V+ uses a 20-pin TQFN-EP package (4mm × 4mm, 0.5mm pitch) with exposed thermal pad (EP) soldered to PCB ground plane for efficient heat dissipation. Package code T2044+4C confirms RoHS-compliant, automotive-grade construction.
| 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 layouts. |
| PGND (Pins 5–7) | Power ground return | Dedicated low-impedance path for high di/dt currents; must be tied to EP and separated from analog ground (GND) to avoid noise coupling. |
| SDA / SCL (Pins 8–9) | I²C bidirectional data/clock | Supports up to 3.4MHz communication; requires ≥500Ω pull-up resistors; 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, critical for sub-1V processor cores. |
| PG (Pin 12) | Open-drain power-good indicator | Asserts low after 120μs when VOUT enters regulation window; requires external pull-up for logic-level signaling to host MCU. |
| EN (Pin 13) | Active-high enable | Triggers soft-start on rising edge; initiates controlled 5.5mV/μs ramp-down during shutdown - prevents system brownout. |
| SYNC (Pin 14) | Frequency synchronization I/O | Configurable as input (accepts 1.8–2.6MHz external clock) or output (2.2MHz PWM signal); enables multi-rail timing coherence. |
| GND (Pin 15) | Analog ground reference | Isolated ground for internal error amplifier and reference; must connect to clean AGND plane, separate from PGND except at single star point. |
| AV (Pin 16) | Analog supply input | Filtered via 100Ω resistor + 1μF ceramic cap to GND; powers precision bandgap and control loop - decoupling prevents regulation instability. |
| ADDR (Pin 17) | I²C address select | Configures LSB of 7-bit slave address (default 0x38); allows up to 8 devices on same I²C bus without address conflict. |
| PV (Pins 18–20) | Main power input supply | Accepts 3.0–5.5V; requires ≥4.7μF ceramic capacitor per PV pin to suppress high-frequency ripple and ensure stable gate drive. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous 6A buck with integrated FETs | Eliminates external MOSFETs and drivers; reduces BOM count by ≥6 components and layout area by >40% vs discrete solutions. |
| Differential remote sensing (RS+/RS−) | Compensates for up to 50mV IR drop across PCB traces - maintains ±2% regulation accuracy at the actual load pin, not IC output. |
| I²C-programmable output voltage (0.5–1.5875V) | Enables dynamic voltage scaling (DVS) for SoC power states; 10mV/12.5mV resolution supports fine-grained energy optimization in AUTOSAR MCAL stacks. |
| Spread-spectrum modulation (+3%) | Reduces peak radiated EMI by >10dB at 2.2MHz fundamental - simplifies EMC validation for ISO 11452-2/2015 automotive compliance. |
| Forced-PWM and skip-mode operation | Ensures consistent 2.2MHz switching under all loads (FPWM) or maximizes light-load efficiency (skip) - selectable via SYNC pin or CONFIG register. |

FAQ
What is the factory-preset output voltage for MAX20010CATPJ/V+?
The MAX20010CATPJ/V+ does not have a factory-preset output voltage; it is a blank (unprogrammed) variant that requires I²C initialization to set the output voltage via the VID register. Unlike pin-strapped versions (e.g., MAX20010CATAJ/V+), the CATPJ/V+ relies entirely on software configuration for VOUT, supporting 0.5V–1.5875V in 10mV or 12.5mV steps. This enables maximum flexibility in production programming and field firmware updates.
Does MAX20010CATPJ/V+ support remote voltage sensing?
Yes, MAX20010CATPJ/V+ supports true differential remote voltage sensing using dedicated RS+ and RS− pins. This feature compensates for voltage drop across PCB traces or connectors between the IC and load, ensuring ±2% regulation accuracy at the actual load point - critical for sub-1V processor cores where even 30mV drop can cause functional failure. RS+ connects to the load's VDD pin; RS− connects to the load's ground reference.
What protection features are integrated into MAX20010CATPJ/V+?
MAX20010CATPJ/V+ integrates overcurrent protection (trip threshold 7.76A–11.64A), overtemperature shutdown (165°C with 15°C hysteresis), undervoltage/overvoltage detection on VOUT (with PGOOD assertion), and soft-start/soft-shutdown sequencing. It also includes LX leakage monitoring and internal fault flagging via the STATUS register (OC, UV, OV, VRHOT bits), enabling host MCU diagnostics without external comparators or supervisors.
Can MAX20010CATPJ/V+ operate in forced-PWM mode?
Yes, MAX20010CATPJ/V+ supports forced-PWM (FPWM) mode via the CONFIG register (FPWM bit = 1) or by applying a valid clock signal (1.8–2.6MHz) to the SYNC pin. FPWM disables skip-mode operation, ensuring constant 2.2MHz switching regardless of load - essential for noise-sensitive applications like radar or audio subsystems where variable-frequency artifacts must be avoided.
Is MAX20010CATPJ/V+ qualified to AEC-Q100 standards?
Yes, MAX20010CATPJ/V+ is fully AEC-Q100 Grade 1 qualified (−40°C to +125°C ambient), with test reports covering stress testing, thermal cycling, HTOL, and ESD per JESD22. Its 20-pin TQFN-EP package (T2044+4C) and internal design meet automotive reliability requirements for under-hood and safety-critical applications, including ISO 26262 ASIL-B ready system integration.
