Product details
Overview
The MAX20010DATPO/VY+ from Analog Devices is a high-efficiency, AEC-Q100 qualified synchronous step-down DC-DC converter delivering up to 6A output current with ±2% output voltage accuracy over load, line, and temperature. It operates from 3.0V–5.5V input and supports programmable output voltages from 0.5V to 1.5875V in 10mV or 12.5mV steps via I²C, and features 2.2MHz fixed-frequency PWM operation with spread-spectrum modulation for EMI reduction-ideal for automotive ADAS power rails and infotainment SoC core supplies.
For engineers reviewing the MAX20010DATPO/VY+ datasheet, MAX20010DATPO/VY+ pinout, MAX20010DATPO/VY+ application, or MAX20010DATPO/VY+ equivalent, key selection considerations include its 20-pin TQFN-EP (4mm × 4mm) package with exposed thermal pad, differential remote sensing capability, I²C-controlled dynamic voltage scaling (DVS), integrated overtemperature and short-circuit protection, and factory-preset output voltage with runtime adjustment.
Technical Context
This IC implements a current-mode, synchronous buck architecture with integrated high-side (31mΩ typical) and low-side (18mΩ typical) MOSFETs, enabling high efficiency across 0–6A loads. Its 2.2MHz switching frequency supports all-ceramic output filtering and minimizes solution footprint while maintaining robust transient response-enhanced in the MAX20010D variant (which MAX20010DATPO/VY+ belongs to) versus the base C version.
The device integrates a 7-bit VID DAC, programmable soft-start/slew rates (5.5–44 mV/μs), and dual-mode operation: forced-PWM (FPWM) for noise-sensitive applications and skip mode for light-load efficiency. The SYNC pin serves as configurable I/O for synchronization or external clock injection, and the PGOOD output provides regulated-rail monitoring with 120μs delay and hysteresis-based OV/UV thresholds.

Pinout & Package
MAX20010DATPO/VY+ is housed in a 20-pin thermally enhanced TQFN package (outline 21-100172, land pattern 90-0409) with 4mm × 4mm footprint and exposed pad (EP) soldered to PCB ground for thermal management. Pin 1 is top-left corner (marked), and pins are arranged in two rows of ten.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX (Pins 1–4) | Switch Node | Connects directly to inductor switch node; multiple parallel pins reduce trace inductance and improve current sharing |
| PGND (Pins 5–7) | Power Ground Return | Low-impedance return path for high-current switching loop; must be tied to EP and local ceramic capacitor ground |
| SDA / SCL (Pins 8–9) | I²C Data/Clock | Open-drain bidirectional interface supporting 3.4MHz operation; requires external pullups ≥500Ω |

| PG (Pin 12) | Power-Good Output | Open-drain signal asserting low until VOUT stabilizes within ±5%–8% window; 120μs timeout after regulation |
| EN (Pin 13) | Enable Input | Active-high logic control initiating soft-start; minimum 1ms low pulse required for clean soft-shutdown |
| SYNC (Pin 14) | Synchronization I/O | Configurable as FPWM input (1.8–2.6MHz) or 2.2MHz PWM output for multi-rail timing alignment |
| GND (Pin 15) | Analog Ground | Reference for internal error amplifier and ADC; must be isolated from noisy PGND except at single-point star ground |
| AV (Pin 16) | Analog Supply | Filtered analog rail (100Ω + 1μF) powering internal reference and control circuitry; improves PSRR and noise immunity |
| ADDR (Pin 17) | I²C Address Select | Binary input setting LSB of 7-bit slave address (0x38–0x3F); determines I²C bus addressing uniqueness |
| PV (Pins 18–20) | Main Power Input | High-current input supply requiring ≥4.7μF ceramic decoupling per PV pin; ties to LX-side of input capacitor |
| EP | Exposed Thermal Pad | Internally connected to die substrate; must be soldered to solid copper pour tied to PGND for θJC = 2°C/W |

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 |
|---|---|---|---|
| MPQ4436-AEC1 | 4A rated, 2.2MHz, no I²C interface; uses external resistor feedback for voltage setting | Lacks dynamic voltage scaling and remote sensing; suitable only for fixed-output applications | Select when cost sensitivity outweighs programmability needs and load current ≤4A |

FAQ
What is the factory-preset output voltage for MAX20010DATPO/VY+?
The MAX20010DATPO/VY+ has a factory-preset output voltage of 1.0V, confirmed in the Ordering Information section of the datasheet. This default setting is established during final test and can be dynamically adjusted via the I²C interface across the full 0.5V–1.5875V range using the VID register (0x06) and VSTEP configuration bit.
Does MAX20010DATPO/VY+ support differential remote sensing, and how is it implemented?
Yes, MAX20010DATPO/VY+ supports differential remote sensing through dedicated RS+ (Pin 11) and RS− (Pin 10) inputs. These pins connect directly to the load's VDD and GND points, enabling the internal error amplifier to regulate voltage precisely at the point-of-load-compensating for PCB trace resistance up to ~100mV drop without requiring external components.
What protection features are integrated into MAX20010DATPO/VY+?
MAX20010DATPO/VY+ integrates overtemperature shutdown (165°C with 15°C hysteresis), cycle-by-cycle overcurrent protection (7.76–11.64A pMOS threshold), short-circuit hiccup mode (4ms off-time), input undervoltage lockout (2.85V rising), and PGOOD monitoring with OV/UV fault detection. All protections are fully autonomous and require no external circuitry.
Can MAX20010DATPO/VY+ operate in forced-PWM mode, and how is it enabled?
Yes, MAX20010DATPO/VY+ supports forced-PWM (FPWM) mode to eliminate frequency variation and associated acoustic noise. It is enabled either by pulling the SYNC pin high (to AV) or by setting the FPWM bit (bit 4) in the CONFIG register (0x04) to '1', overriding skip-mode behavior regardless of SYNC pin state.
What is the thermal performance of MAX20010DATPO/VY+ on a standard four-layer PCB?
On a JEDEC-standard four-layer board, MAX20010DATPO/VY+ achieves a junction-to-ambient thermal resistance (θJA) of 33°C/W and junction-to-case (θJC) of 2°C/W. With proper thermal pad soldering to a ≥250mm² copper pour tied to PGND, the device sustains 6A continuous output at +85°C ambient without derating.
