Product details
Overview
The MAX20010DATPQ/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, 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 high-precision processor core supply.
For engineers reviewing the MAX20010DATPQ/V+ datasheet, MAX20010DATPQ/V+ pinout, MAX20010DATPQ/V+ application, or MAX20010DATPQ/V+ equivalent, key selection criteria include AEC-Q100 qualification, 20-pin TQFN-EP (4mm × 4mm) package with exposed thermal pad, I²C-configurable slew rate and voltage step size, and integrated overcurrent/overtemperature protection with PGOOD monitoring.
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 power switches. Its dual-mode operation-forced-PWM (FPWM) and skip-mode-dynamically optimizes efficiency across load conditions while maintaining EMI compliance via 2.2MHz switching and programmable ±3% spread-spectrum modulation.
The device integrates differential remote sense (RS+/RS−), programmable soft-start/slew rates (5.5–44 mV/μs), and configurable SYNC I/O for system-level clock synchronization. All protections-including overcurrent latch-off, thermal shutdown at 165°C with 15°C hysteresis, and PGOOD with 120μs delay-are fully autonomous and require no external components.

Pinout & Package
MAX20010DATPQ/V+ uses a 20-pin TQFN-EP package (4mm × 4mm, 0.5mm pitch) with exposed thermal pad (EP) connected to PGND. The package supports high-power dissipation and meets automotive mechanical reliability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX (Pins 1–4) | Switch node connection | Drives external inductor; requires low-inductance routing to minimize switching losses and EMI. |
| PGND (Pins 5–7) | Power ground return | Must be tied directly to EP and inductor ground plane; separates high-current return from analog ground. |
| SDA / SCL (Pins 8–9) | I²C bidirectional data/clock | Supports DVS, status readback, and configuration; requires ≥500Ω pull-up resistors per bus specification. |
| RS+/RS− (Pins 10–11) | Differential remote sense inputs | Compensates for PCB IR drop to maintain ±2% regulation at load point, critical for low-voltage cores. |
| PG (Pin 12) | Open-drain power-good indicator | Asserts low for 120μs after VOUT enters regulation window; requires external pull-up for logic-level signaling. |
| EN (Pin 13) | Active-high enable | Initiates soft-start on rising edge; controls sequencing in multi-rail systems with 140μs enable delay. |
| SYNC (Pin 14) | Configurable sync I/O | Can accept 1.8–2.6MHz external clock (FPWM mode) or output internal 2.2MHz for multi-device synchronization. |
| GND (Pin 15) | Analog ground reference | Isolated from PGND to reduce noise coupling into feedback and control circuits. |
| AV (Pin 16) | Analog supply input | Filtered separately (100Ω + 1μF) to stabilize internal reference and error amplifier performance. |
| ADDR (Pin 17) | I²C address select | Sets LSB of 7-bit slave address (0x38–0x3F); enables multiple devices on same I²C bus without conflict. |
| PV (Pins 18–20) | Main power input | Accepts 3.0–5.5V; requires ≥4.7μF ceramic capacitor per pin to suppress high-frequency ripple. |

FAQ
What is the maximum output current capability of the MAX20010DATPQ/V+?
The MAX20010DATPQ/V+ delivers up to 6A continuous output current under specified thermal conditions (TA ≤ +125°C, θJA = 33°C/W). This rating assumes proper PCB layout with full use of the exposed thermal pad and adequate copper area. Peak current capability is limited by the internal pMOS current-limit threshold of 7.76A–11.64A, but sustained operation above 6A requires derating based on junction temperature monitoring.
Does the MAX20010DATPQ/V+ support dynamic voltage scaling (DVS) via I²C?
Yes, the MAX20010DATPQ/V+ 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), enabling controlled transitions during DVS events without overshoot or instability.
What is the purpose of the RS+ and RS− pins on the MAX20010DATPQ/V+?
The RS+ and RS− pins on the MAX20010DATPQ/V+ provide differential remote voltage sensing to compensate for IR drop across PCB traces between the regulator output and the load. By measuring voltage directly at the load point, the IC maintains ±2% regulation accuracy at the actual point of use-even with up to 100mV trace resistance-critical for low-voltage, high-current automotive SoC cores.
How does the MAX20010DATPQ/V+ handle overcurrent conditions?
Under overcurrent or short-circuit conditions, the MAX20010DATPQ/V+ initiates automatic protection: if VOUT falls below 50% of the set value while in current limit, the device shuts off for 4ms (at 2.2MHz switching frequency), then repeats soft-start. This hiccup-mode behavior prevents thermal runaway and enables self-recovery once the fault is removed-no external circuitry or host intervention is required for basic protection.
Is the MAX20010DATPQ/V+ compatible with external clock synchronization?
Yes, the MAX20010DATPQ/V+ supports external clock synchronization via the SYNC pin. When configured as an input (SO[1:0] = 00 or 01), it accepts external clocks from 1.8MHz to 2.6MHz to force fixed-frequency PWM operation. When configured as an output (SO[1:0] = 10), it outputs the internal 2.2MHz switching frequency, enabling precise timing alignment across multiple converters in complex automotive power trees.
