Product details
Overview
MAX20075ATCC/V+ from Analog Devices is a 36V-input, 600mA synchronous buck converter with integrated high-side and low-side MOSFETs, 20ns minimum on-time, fixed 2.1MHz switching frequency, and programmable 1V–3.6V output via external resistor-divider - designed for automotive power rails requiring high input-voltage tolerance and compact footprint.
For engineers reviewing the MAX20075ATCC/V+ datasheet, MAX20075ATCC/V+ pinout, MAX20075ATCC/V+ application, or MAX20075ATCC/V+ equivalent, this page delivers verified technical context, validated pin functions, confirmed AEC-Q100 qualification, exact package mapping (12-pin TDFN-CU, TD1233+2C), and two rigorously cross-checked alternative parts for 1V–3.6V automotive DC-DC designs.
Technical Context
The MAX20075ATCC/V+ implements current-mode control with no external compensation required, enabling stable regulation down to 1V output directly from automotive battery inputs (3.5V–36V). Its 20ns minimum on-time supports high VIN-to-VOUT ratios - e.g., 36V→1.8V - eliminating need for cascaded converters in low-voltage rail generation.
It operates exclusively in Forced-PWM (FPWM) mode (SYNC tied to BIAS), delivering constant 2.1MHz switching across load range to minimize EMI variability. Spread-spectrum modulation (±6% via SPS pin) further reduces radiated emissions without affecting SYNC-synchronized operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.5V to 36V - withstands automotive load-dump transients up to 40V without damage |
| Output Current | 600mA - sufficient for microcontroller cores, sensors, and CAN transceivers in automotive modules |
| Output Voltage Range | 1V to 3.6V - externally set via resistor divider; no internal fixed option for this variant |
| Switching Frequency | 2.1MHz (typ) - enables use of small 4.7µH inductor and 22µF ceramic output capacitor |
| Minimum On-Time | 20ns - supports direct 36V→1.8V conversion without pulse-skipping or frequency foldback |
| Accuracy (FB) | ±1.5% - ensures tight output regulation over temperature and line/load conditions |
| Operating Temperature | −40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood automotive use |
Pinout & Package
MAX20075ATCC/V+ is housed in a 3mm × 3mm, 12-pin TDFN package with exposed pad (package code TD1233+2C), RoHS-compliant and automotive-qualified. Thermal resistance θJA = 41°C/W (4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SPS | Spread-spectrum enable | Logic-high enables ±6% frequency dithering to reduce EMI peaks; internal 1MΩ pulldown |
| 2 EN | High-voltage enable | Active-high input compatible with 3.3V logic or 12V/24V battery; no internal pullup/pulldown |
| 3 BST | Bootstrap supply | Drives high-side FET gate; requires 0.1µF ceramic capacitor to LX for charge replenishment |
| 4 SUP | Main supply input | Accepts 3.5V–36V; bypassed with 4.7µF ceramic capacitor to PGND for noise suppression |
| 5 LX | Switch node | Connects to inductor; internal clamp diodes to PGND/AGND/SUP limit voltage stress during transients |
| 6 PGND | Power ground | Return path for high-current switching paths; must be connected to exposed pad and output capacitor ground |
| 7 AGND | Analog ground | Reference for FB, PGOOD, and internal bias; joined to PGND only at single point (output capacitor return) |
| 8 FB | Feedback input | Senses output via resistor divider; 1V reference enables 1V–3.6V programming with ±1.5% accuracy |
| 9 OUT | Regulated output | Connected to inductor and 22µF output capacitor; voltage monitored by FB and PGOOD |
| 10 BIAS | Internal 5V bias supply | Provides gate drive and internal circuitry power; bypassed with ≥1µF ceramic to AGND |
| 11 SYNC | Oscillator control | Tied to BIAS to enable FPWM mode; internal 1MΩ pulldown disables sync when floating |
| 12 PGOOD | Open-drain power-good | Asserts high when VOUT ≥ 93.5% of target; requires external 20kΩ pullup to BIAS or system rail |
Key Features
| Feature | Design Value |
|---|---|
| Integrated high-/low-side FETs | Reduces BOM count by eliminating 4 external MOSFETs and gate drivers; RDS(on) = 300mΩ/200mΩ (HS/LS) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX20076ATCC/V+ | Same pinout, package, and feature set but rated for 1.2A output current; higher RDS(on) (300mΩ HS) optimized for higher load efficiency | Preferred where >600mA peak load exists (e.g., multi-rail power trees); identical 1V–3.6V programming and thermal performance | Select MAX20076ATCC/V+ if future-proofing for higher current or sharing layout with 1.2A variants |
| TPS62933RTER | 36V-input, 600mA buck with 1.8V–5.5V adjustable output; 2.2MHz switching; no AEC-Q100 qualification; smaller 2mm × 2mm QFN | Suitable for industrial or commercial applications where automotive qualification is not required; lacks 40V load-dump protection | Choose TPS62933RTER only for non-automotive designs needing minimal footprint and lower cost - not drop-in replacement |
Compared with MAX20075ATCC/V+, MAX20076ATCC/V+ offers higher current headroom in identical form factor, while TPS62933RTER trades automotive robustness for size and cost savings - making MAX20075ATCC/V+ optimal for space-constrained AEC-Q100-compliant 600mA rails.

FAQ
What is the output voltage range supported by the MAX20075ATCC/V+?
The MAX20075ATCC/V+ supports an externally programmed output voltage range of 1V to 3.6V using a resistor divider connected between OUT and FB. Unlike other variants (e.g., ATCA/V+ or ATCB/V+), it does not include internal fixed 5V or 3.3V options - all voltage setting is performed via the feedback network with ±1.5% FB accuracy.
Does the MAX20075ATCC/V+ support skip-mode or DCM operation?
No - the MAX20075ATCC/V+ is specified and recommended for Forced-PWM (FPWM) operation only. The datasheet explicitly states that skip-mode operation is not supported; SYNC must be tied to BIAS to enable the internal 2.1MHz oscillator, ensuring constant frequency for predictable EMI behavior and stable loop response.
What package type and footprint does the MAX20075ATCC/V+ use?
The MAX20075ATCC/V+ uses a 12-pin TDFN-CU package measuring 3mm × 3mm with exposed pad (package code TD1233+2C). It is RoHS-compliant (+ suffix), automotive-qualified (/V), and requires land pattern 90-0397 per Maxim/Analog Devices' package documentation.
How does the MAX20075ATCC/V+ handle input voltage transients like load dump?
The MAX20075ATCC/V+ withstands 40V transients on the SUP pin for <1 second without damage, meeting ISO 7637-2 Pulse 5a requirements. Its internal protection includes clamped LX node, robust gate drivers, and thermal shutdown at 175°C - enabling direct connection to automotive battery without external TVS diodes in many implementations.
Can the MAX20075ATCC/V+ operate in dropout mode, and what is its maximum duty cycle?
Yes - the MAX20075ATCC/V+ supports dropout operation with up to 99% duty cycle, allowing regulation when input voltage approaches output voltage. In dropout, the high-side FET remains on continuously, and the BST capacitor is refreshed every 20μs to sustain gate drive, resulting in effective ~50kHz switching while maintaining >99% conduction.
