Product details
Overview
MAX20072ATAC/V+T from Analog Devices is a 1A, 2.2MHz synchronous step-down DC-DC converter in an 8-pin TDFN-EP package, delivering factory-preset 1.15V output with ±1.5% accuracy across -40°C to +125°C. It features current-mode control, PGOOD monitoring, enable input, and spread-spectrum operation for automotive point-of-load regulation.
For engineers reviewing the MAX20072ATAC/V+T datasheet, MAX20072ATAC/V+T pinout, MAX20072ATAC/V+T application, or MAX20072ATAC/V+T equivalent, key selection considerations include its 1.15V fixed output, 3.0V–5.5V input range, 2.2MHz switching frequency enabling all-ceramic designs, and AEC-Q100 qualified automotive-grade thermal and reliability performance.
Technical Context
The MAX20072ATAC/V+T implements a current-mode PWM architecture with internal high-side (80–300mΩ) and low-side (50–200mΩ) MOSFETs, supporting forced-PWM or skip-mode operation via the SYNC pin. Its 0.5V internal reference enables precise feedback control even in fixed-output configurations.
It integrates comprehensive protection: overcurrent limiting (1.4–1.6A threshold), overtemperature shutdown at +165°C with 15°C hysteresis, 107% OV/93% UV PGOOD monitoring, and 0.85ms soft-start. Spread-spectrum operation (±3%) reduces EMI without external components.

Pinout & Package
8-pin TDFN-EP (2mm × 2mm, 0.85mm height) with exposed thermal pad (EP) soldered to PCB ground plane for enhanced thermal performance and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 AV | Analog supply rail | Separate analog power input; requires 1µF capacitor + 10Ω series resistor to PV for noise isolation and PSRR improvement. |
| 2 SYNC | Mode control input | Drives forced-PWM (high) or skip mode (low/floating); enables dynamic efficiency optimization across load range. |
| 3 PGND | Power ground return | Dedicated low-impedance path for high-current switch node return; must be connected directly to EP and system GND. |
| 4 PV | Main power input | 3.0–5.5V supply input; requires ≥4.7µF ceramic capacitor placed adjacent to pin for high-frequency ripple suppression. |
| 5 PG | Open-drain PGOOD output | Active-low signal asserting after 10µs delay when output deviates >7%; requires external pullup ≥2kΩ. |
| 6 LX | Switch node | Connection to inductor's switched side; carries high di/dt; must be routed as short and wide as possible to minimize EMI. |
| 7 EN | Enable control | Active-high logic input (VIH = 1.5V min); initiates 0.85ms soft-start on rising edge; enters shutdown on falling edge. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX20072ATAA/V+T | Same 1A rating and 2.2MHz frequency, but adjustable output (0.5V–3.8V) via external resistors; no spread spectrum. | Suitable for designs requiring flexible VOUT tuning or multi-rail support; lacks EMI reduction feature. | Select when output voltage must be customized per platform or when spread-spectrum is unnecessary for EMI compliance. |
| TPS6286418RTER | 1.8V fixed output (not 1.15V), 1A, 2.25MHz, integrated compensation, smaller 1.5mm × 1.5mm QFN; no spread spectrum or AEC-Q100 qualification. | Targeted at consumer/portable applications; lacks automotive temp range and PGOOD OV/UV thresholds. | Choose only for non-automotive, non-safety-critical designs where 1.8V matches system needs and AEC-Q100 is not required. |
Compared with MAX20072ATAA/V+T, the MAX20072ATAC/V+T offers guaranteed 1.15V output and built-in spread-spectrum EMI reduction-critical for camera and radar modules-while the TPS6286418RTER trades automotive qualification and precision for smaller size and lower cost in commercial applications.

FAQ
What is the output voltage of the MAX20072ATAC/V+T and how is it set?
The MAX20072ATAC/V+T delivers a factory-preset 1.15V output with ±1.5% accuracy over load, line, and temperature. This fixed value is laser-trimmed during manufacturing, eliminating the need for external feedback resistors. The device uses an internal 0.5V reference and dedicated trim bits to achieve this precision without customer-adjustable components.
Does the MAX20072ATAC/V+T support synchronization to an external clock?
Yes, the MAX20072ATAC/V+T supports external synchronization via the SYNC pin. When driven high (to PV or external clock), it operates in forced-PWM mode at the applied frequency (1.7–2.4MHz). When SYNC is grounded or floating, it defaults to skip mode for improved light-load efficiency. The internal oscillator runs at 2.2MHz nominal when unsynchronized.
Is the MAX20072ATAC/V+T qualified for automotive applications?
Yes, the MAX20072ATAC/V+T is AEC-Q100 Grade 1 qualified, rated for operation from -40°C to +125°C ambient temperature. It includes automotive-specific protections including overtemperature shutdown at +165°C (15°C hysteresis), robust PGOOD OV/UV monitoring, and 100% production testing at +25°C with design validation across the full temperature range.
What protection features does the MAX20072ATAC/V+T include?
The MAX20072ATAC/V+T integrates overcurrent limiting (1.4–1.6A threshold), overtemperature shutdown (+165°C), PGOOD output with 107% OV and 93% UV detection, and 0.85ms soft-start. It also features current-mode control for inherent cycle-by-cycle current limiting and fast transient response, critical for automotive safety-critical loads.
Can the MAX20072ATAC/V+T operate with all-ceramic output capacitors?
Yes, the MAX20072ATAC/V+T is explicitly designed for stability with low-ESR ceramic output capacitors. Its current-mode control architecture and internal compensation eliminate the need for electrolytic or tantalum capacitors. Recommended output capacitance is calculated as COUT_NOM = 27.5µs × IMAX / VOUT - e.g., ~24µF for 1.15V/1A - using X7R/X5R ceramics.
