Product details
Overview
The MAX20075DATCD/VY+T from Analog Devices is a 0.6A synchronous buck converter IC with integrated high-side and low-side MOSFETs, operating from 3.5V to 36V input and delivering ±2% output accuracy at 5V or 3.3V fixed outputs (or 1V–10V adjustable), featuring 2.1MHz switching, 20ns minimum on-time, and 3.5µA quiescent current in standby - designed for automotive power rails requiring compact, AEC-Q100-compliant DC-DC conversion.
For engineers reviewing the MAX20075DATCD/VY+T datasheet, MAX20075DATCD/VY+T pinout, MAX20075DATCD/VY+T application, or MAX20075DATCD/VY+T equivalent, key selection considerations include its 99% dropout capability, spread-spectrum EMI reduction, PGOOD monitoring, 40V load-dump tolerance, and side-wettable 12-pin TDFN package with exposed pad for thermal reliability in harsh environments.
Technical Context
This current-mode-controlled buck regulator integrates both power switches and requires no external compensation. Its 20ns minimum on-time enables direct step-down from automotive battery (e.g., 12V → 2.5V) without cascaded stages, while the 2.1MHz fixed-frequency operation minimizes inductor and capacitor size and avoids AM-band interference.
It supports dual operating modes via the SYNC pin: forced PWM (FPWM) for constant-frequency EMI control or skip mode for ultra-low IQ at light loads. The SPS pin enables ±6% spread-spectrum modulation of the internal oscillator, active only during internally generated switching - independent of external SYNC clocking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 0.6A continuous - sufficient for powering microcontrollers, sensors, and CAN transceivers in automotive ECUs. |
| Input Voltage Range | 3.5V to 36V - supports cold-crank (down to 3.5V) and 40V load-dump transient tolerance per AEC-Q100. |
| Quiescent Current | 3.5µA typical in standby - enables always-on systems (e.g., body control modules) with minimal battery drain. |
| Switching Frequency | 2.1MHz nominal - allows use of small 4.7µH inductors and 22µF ceramic output capacitors for space-constrained layouts. |
| Output Accuracy | ±2% at 5V/3.3V fixed outputs - ensures stable logic supply under full temperature (-40°C to +125°C) and line/load variation. |
| Minimum On-Time | 20ns - enables high step-down ratios (e.g., 12V → 1.8V) without pulse-skipping instability or external frequency scaling. |
| Duty Cycle Max | 99% - sustains regulation during deep dropout (e.g., 5.5V input → 5V output), critical for automotive brownout resilience. |
| PGOOD Threshold | Rising at 93.5% VOUT - provides precise power-rail monitoring for system reset sequencing and fault detection. |
Pinout & Package
MAX20075DATCD/VY+T is housed in a 3mm × 3mm, 12-pin side-wettable TDFN package (package code TD1233Y+2C) with exposed thermal pad connected to PGND - optimized for automated optical inspection (AOI) and high-reliability solder joint formation in automotive PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SPS | Spread-spectrum enable | Logic-high enables ±6% frequency dithering to reduce peak EMI emissions; internal 1MΩ pulldown ensures default disable. |
| 2 EN | High-voltage enable input | Accepts 0–36V logic; no internal pullup/pulldown preserves ultra-low IQ; compatible with MCU GPIO or automotive KEY signals. |
| 3 BST | Bootstrap capacitor node | Drives high-side gate; requires 0.1µF ceramic capacitor to LX for reliable HS FET turn-on, especially near dropout. |
| 4 SUP | Main input supply | Connects to 3.5–36V source; bypassed with 4.7µF ceramic to PGND to suppress high-frequency switching noise. |
| 5 LX | Switching node | Connects to inductor; carries high di/dt current; internal clamp diodes protect against inductive kickback during startup/fault. |
| 6 PGND | Power ground | Low-impedance return path for LX, SUP, and output capacitor; must be separated from AGND to avoid noise coupling. |
| 7 AGND | Analog ground | Reference for FB, PGOOD, and internal error amplifier; connects to quiet ground plane and decoupling capacitor at BIAS. |
| 8 FB | Feedback input | Senses output via resistor divider; 1.0V ±1.5% reference enables precise 1V–10V programmable regulation or ties to BIAS for fixed 5V/3.3V. |
| 9 OUT | Regulated output | Delivers up to 0.6A; bypassed with 22µF ceramic to PGND; voltage sensed at this node for loop stability and PGOOD assertion. |
| 10 BIAS | Internal 5V LDO output | Supplies internal circuitry; requires ≥1µF ceramic to AGND; powers FB divider and PGOOD pullup when not in skip mode. |
| 11 SYNC | Mode control / sync input | Ground or open = skip mode (low IQ); tied to BIAS = forced PWM (constant fSW); internal 1MΩ pulldown ensures default skip. |
| 12 PGOOD | Open-drain power-good flag | Active-high signal pulled low when VOUT drops below 93% nominal; requires external 20kΩ pullup to BIAS or system rail. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX20075DATCA/V+ | Same 0.6A rating and 3.5µA IQ, but uses standard (non-side-wettable) 12-pin TDFN package (TD1233+2C); lacks AOI-friendly solderability. | Preferred for cost-sensitive non-automotive designs where optical inspection is not required and thermal performance margin is adequate. | Select MAX20075DATCA/V+ only if board-level AOI is unnecessary and PCB assembly process does not require side-wettable leads. |
| LM61480QRTWRQ1 | Texas Instruments' AEC-Q100 1.2A buck; higher current, 2.2MHz fSW, but 11µA IQ (vs. 3.5µA); no spread-spectrum; 16-pin WQFN. | Better suited for higher-current ADAS domain controllers; less optimal for ultra-low-power always-on nodes due to higher standby IQ. | Choose LM61480QRTWRQ1 when >0.6A output or tighter output ripple is needed, accepting higher IQ and larger footprint. |

This rating applies for ≤1s duration and is validated across temperature.
Does the MAX20075DATCD/VY+T support adjustable output voltage, and what is the accuracy?
Yes, the MAX20075DATCD/VY+T supports externally adjustable output from 1V to 10V using a resistor divider from OUT to FB to AGND, with feedback reference voltage accuracy of ±1.5% - enabling precise regulation across the full range. Factory-trimmed 5V and 3.3V versions offer ±2% output accuracy over temperature and line.
How does the MAX20075DATCD/VY+T achieve ultra-low quiescent current, and under what conditions is 3.5µA realized?
The MAX20075DATCD/VY+T achieves 3.5µA typical quiescent current in standby mode by disabling most internal circuitry - including the high-voltage LDO - when output current falls below ~5mA and skip mode is active. This 3.5µA value is specified for factory-trimmed 3.3V/5V variants at no load and TA = +25°C, per Electrical Characteristics table.
What package type is used for the MAX20075DATCD/VY+T, and why is it significant for automotive applications?
The MAX20075DATCD/VY+T uses a 3mm × 3mm, 12-pin side-wettable TDFN package (TD1233Y+2C). Its side-wettable leads enable automated optical inspection (AOI) of solder joints - a critical manufacturing requirement for automotive electronics - while the exposed thermal pad improves heat dissipation in sealed enclosures.
Can the MAX20075DATCD/VY+T operate in dropout, and what is its minimum operating input voltage relative to output?
Yes, the MAX20075DATCD/VY+T supports dropout operation with up to 99% duty cycle, allowing regulation when input voltage approaches the output voltage. For example, it can maintain 5V output with input as low as ~5.1V - essential for automotive cold-crank scenarios where battery voltage dips below 6V, and confirmed by its ability to sustain 99% duty cycle in datasheet test conditions.
