Product details
Overview
MAX20010DATPP/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, and integrates low RDS(ON) MOSFETs for high efficiency in compact layouts.
For engineers reviewing the MAX20010DATPP/V+ datasheet, MAX20010DATPP/V+ pinout, MAX20010DATPP/V+ application, or MAX20010DATPP/V+ equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade AEC-Q100 qualification, real-world transient response data, and two rigorously cross-checked alternative parts with documented functional and packaging differences.
Technical Context
The MAX20010DATPP/V+ implements current-mode control with integrated pMOS (31–55mΩ) and nMOS (18–31mΩ) power switches, enabling stable 6A delivery at 2.2MHz switching frequency. Its dual-mode operation-forced-PWM for noise-sensitive timing-critical loads and skip mode for light-load efficiency-supports dynamic system-level power management.
Differential remote sensing (RS+/RS−), programmable soft-start slew rates (5.5–44 mV/μs), and I²C-configurable voltage steps (10mV or 12.5mV) allow precise rail tuning for ADAS SoCs and microcontrollers. The device includes PGOOD with 120μs delay, thermal shutdown at 165°C, and overcurrent protection with 4ms hiccup recovery.

Pinout & Package
MAX20010DATPP/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 numbering follows standard top-view orientation with Pin 1 at top-left corner.
| 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 |
| PGND (Pins 5–7) | Power ground return | Low-impedance path for high di/dt currents; must be tied to EP and local ceramic capacitor ground |
| SDA / SCL | I²C bidirectional data / clock | Supports 3.4MHz DVS commands; requires ≥500Ω pull-up resistors and noise filtering per automotive EMC requirements |
| RS+ / RS− | Differential remote sense inputs | Compensates for PCB trace IR drop to maintain ±2% regulation at load point, critical for high-current rails |
| PG | Open-drain power-good indicator | Asserts low for 120μs after VOUT enters regulation window; requires external pull-up to logic rail (e.g., 3.3V) |
| EN | Active-high enable | Triggers soft-start on rising edge; minimum 1ms low pulse required for full soft-shutdown sequence completion |
| SYNC | Frequency synchronization I/O | Configurable as input (1.8–2.6MHz external clock) or output (2.2MHz internal PWM); enables multi-rail phase alignment |
| ADDR | I²C slave address select | Allows up to 8 unique addresses on same bus (0x38–0x3F write, 0x70–0x7F read) for multi-converter systems |
| AV / GND / PV | Analog supply / analog ground / power input | Separate AV/GND reduces noise coupling into error amplifier; PV pins share bulk capacitance (≥4.7μF ceramic) |

FAQ
What is the maximum output current capability of the MAX20010DATPP/V+?
The MAX20010DATPP/V+ delivers up to 6A continuous output current under typical thermal conditions (TA = +70°C, four-layer PCB). Its integrated low RDS(ON) MOSFETs (pMOS: 31–55mΩ, nMOS: 18–31mΩ) and 4mm × 4mm TQFN-EP package with exposed pad enable sustained 6A operation within AEC-Q100 Grade 0 temperature limits (-40°C to +125°C).
Does the MAX20010DATPP/V+ support dynamic voltage scaling (DVS) via I²C?
Yes, the MAX20010DATPP/V+ supports full dynamic voltage scaling through its standard I²C interface (up to 3.4MHz). Output voltage is adjustable from 0.5V to 1.27V in 10mV steps or 0.625V to 1.5875V in 12.5mV steps using the VID register (0x07), with programmable slew rates (5.5–44 mV/μs) controlled via the SLEW register (0x06).
What is the purpose of the RS+ and RS− pins on the MAX20010DATPP/V+?
The RS+ and RS− pins on the MAX20010DATPP/V+ provide differential remote voltage sensing to compensate for IR drop across PCB traces between the IC and load. This ensures ±2% output voltage regulation accuracy at the actual load point - critical for high-current automotive SoC rails where trace resistance can exceed 50mΩ.
Is the MAX20010DATPP/V+ qualified for automotive applications?
Yes, the MAX20010DATPP/V+ is fully AEC-Q100 qualified (Grade 0) for automotive use, with guaranteed operation from -40°C to +125°C ambient temperature and 150°C junction limit. It includes automotive-specific protections including PGOOD with 120μs delay, thermal shutdown with 15°C hysteresis, and short-circuit hiccup mode.
Can the MAX20010DATPP/V+ synchronize its switching frequency with other converters?
Yes, the MAX20010DATPP/V+ features a bidirectional SYNC pin that can be configured as either input (accepting 1.8–2.6MHz external clock) or output (emitting 2.2MHz internal PWM). This enables precise phase alignment across multiple rails in complex automotive power trees, reducing aggregate input ripple and EMI peaks.
