Product details
Overview
MAX20075DATCE/V+ from Analog Devices is a 36V-input, 0.6A synchronous buck converter with integrated high-side and low-side MOSFETs, 3.5µA quiescent current in standby mode, ±2% output voltage accuracy at 3.3V, and 20ns minimum on-time enabling direct regulation of sub-3V rails from automotive battery sources. It operates across -40°C to +125°C and is AEC-Q100 qualified for under-hood power conversion.
For engineers reviewing the MAX20075DATCE/V+ datasheet, MAX20075DATCE/V+ pinout, MAX20075DATCE/V+ application, or MAX20075DATCE/V+ equivalent, key selection criteria include its 3.3V fixed output configuration, 12-pin side-wettable TDFN package, 2.1MHz switching frequency, spread-spectrum EMI reduction, and 40V load-dump tolerance - all critical for automotive infotainment, ADAS camera modules, and industrial sensor nodes requiring ultra-low IQ and high-voltage resilience.
Technical Context
The MAX20075DATCE/V+ implements current-mode control with no external compensation required, enabling stable operation with minimal external components. Its 20ns minimum on-time and 99% maximum duty cycle support wide VIN-to-VOUT ratios - specifically optimized for regulating <3V outputs directly from 12V/24V automotive batteries without cascaded converters.
It features dual operating modes: skip mode (SYNC grounded) for ultra-low IQ at light loads, and forced PWM (SYNC tied to BIAS) for constant-frequency EMI control. The SPS pin enables ±6% spread-spectrum modulation of the 2.1MHz internal oscillator, reducing peak radiated emissions without affecting SYNC-synchronized operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 0.6A continuous - sufficient for powering microcontrollers, CAN transceivers, and image sensors in compact automotive modules. |
| Input Voltage Range | 3.5V to 36V - supports 12V/24V automotive systems and tolerates 40V load-dump transients per AEC-Q100. |
| Fixed Output Voltage | 3.3V ±2% - factory-trimmed for precision rail generation without external feedback resistors. |
| Quiescent Current | 3.5µA at no load - extends battery life in always-on vehicle subsystems such as telematics and door modules. |
| Switching Frequency | 2.1MHz (typ) - enables use of small 4.7µH inductors and 22µF ceramic output capacitors, minimizing solution footprint. |
| Minimum On-Time | 20ns - allows direct 3.3V (or lower) regulation from 12V battery without intermediate conversion stages. |
| Operating Temperature | -40°C to +125°C - qualified for under-hood placement in engine control units and body electronics. |
Pinout & Package
MAX20075DATCE/V+ is housed in a 3mm × 3mm, 12-pin side-wettable TDFN package (package code TD1233Y+2C) with exposed thermal pad connected to PGND. This package supports automated optical inspection (AOI) and improves solder joint reliability in automotive reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SPS | Spread-spectrum enable input | Logic-high enables ±6% frequency dithering to reduce EMI peaks; internal 1MΩ pulldown ensures default disable. |
| 2 EN | High-voltage enable input | Accepts 3.3V–36V logic; enables device when >2.4V; no internal pullup/pulldown preserves ultra-low IQ. |
| 3 BST | Bootstrap supply for high-side gate driver | Requires 0.1µF capacitor to LX; sustains gate drive during 99% duty-cycle dropout operation. |
| 4 SUP | Main input supply | Connect 4.7µF ceramic capacitor to PGND; handles 3.5V–36V input with 40V transient tolerance. |
| 5 LX | Switch node | Drives external 4.7µH inductor; high-impedance when disabled; clamped internally to PGND/SUP. |
| 6 PGND | Power ground | Return path for high-current switching; must be low-inductance plane separate from AGND. |
| 7 AGND | Analog ground | Reference for FB, PGOOD, and internal bias; isolated from PGND to minimize noise coupling. |
| 8 FB | Feedback input | Internally connected to BIAS for 3.3V fixed output; externally configurable for 1V–10V via resistor divider. |
| 9 OUT | Regulated output | Bypass with 22µF ceramic capacitor to PGND; monitored by PGOOD for system sequencing. |
| 10 BIAS | Internal 5V LDO output | Supplies internal circuitry; requires ≥1µF ceramic capacitor to AGND; powers PGOOD pullup and SYNC/SPS logic. |
| 11 SYNC | Mode select/synchronization input | Ground = skip mode; BIAS = forced PWM; internal 1MΩ pulldown enables default skip operation. |
| 12 PGOOD | Open-drain power-good indicator | Active-high signal asserting VOUT ≥93.5% of nominal; requires external 20kΩ pullup to BIAS or system rail. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous buck with integrated FETs | Eliminates external MOSFETs and drivers - reduces BOM count and PCB area in space-constrained automotive modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX20075DATCC/V+ | Same 0.6A rating and 3.3V fixed output, but uses standard TDFN (not side-wettable); lacks AOI-compatible leads. | Preferred for cost-sensitive non-automotive industrial designs where solder joint inspection is not mandated. | Select MAX20075DATCC/V+ only if side-wettable leads and AEC-Q100 traceability are unnecessary. |
| LM61480RQWR | 0.8A output, 3.5V–36V input, 1.5MHz switching, no spread-spectrum, not AEC-Q100 qualified. | Suitable for commercial-grade automotive accessories or industrial controls where qualification is optional. | Choose LM61480RQWR when higher output current is needed and AEC-Q100 compliance is not required. |
Compared with MAX20075DATCC/V+, the MAX20075DATCE/V+ provides enhanced manufacturability via side-wettable leads and full AEC-Q100 documentation; versus LM61480RQWR, it trades 0.2A current headroom for guaranteed automotive qualification, lower IQ, and integrated EMI reduction features.

FAQ
What output voltage does the MAX20075DATCE/V+ deliver?
The MAX20075DATCE/V+ delivers a factory-trimmed fixed 3.3V output with ±2% accuracy over temperature and line regulation. It achieves this using internal feedback routing - no external resistor divider is required unless configuring for adjustable 1V–10V output, which is not applicable to this specific variant.
Is the MAX20075DATCE/V+ qualified for automotive applications?
Yes, the MAX20075DATCE/V+ is AEC-Q100 Grade-1 qualified (-40°C to +125°C ambient), with validated performance across thermal cycling, humidity, and mechanical shock tests. Its 40V load-dump tolerance, 3.5V cold-crank start capability, and 99% dropout operation make it suitable for under-hood and cabin-mounted automotive electronics.
What package type does the MAX20075DATCE/V+ use?
The MAX20075DATCE/V+ uses a 3mm × 3mm, 12-pin side-wettable TDFN package (package code TD1233Y+2C) with exposed thermal pad. This package enables automated optical inspection of solder joints and improves thermal dissipation and mounting reliability in automotive reflow processes.
How does the MAX20075DATCE/V+ achieve ultra-low quiescent current?
The MAX20075DATCE/V+ achieves 3.5µA typical quiescent current by entering standby mode when load current drops below ~5mA: it disables the internal high-voltage LDO and powers internal circuitry from the output rail. This behavior is confirmed in datasheet Section "Achieving High Efficiency at Light Loads" and applies specifically to 3.3V fixed-output variants like MAX20075DATCE/V+.
Does the MAX20075DATCE/V+ support spread-spectrum frequency modulation?
Yes, the MAX20075DATCE/V+ supports spread-spectrum modulation via the SPS pin: pulling SPS high enables ±6% dithering of its 2.1MHz internal oscillator frequency, reducing peak radiated EMI without affecting functional timing or SYNC-synchronized operation. The feature is active only when the internal oscillator is used - not during external clock synchronization.
