Product details
Overview
MAX20076ATCC/V+ from Analog Devices is a 3.5V–36V input, 1.2A synchronous buck converter in a 12-pin TDFN package, delivering programmable 1V–3.6V output with ±1.5% FB accuracy, 20ns minimum on-time, and 2.1MHz fixed switching frequency-designed for automotive power rails requiring compact, high-ratio DC-DC conversion.
For engineers reviewing the MAX20076ATCC/V+ datasheet, MAX20076ATCC/V+ pinout, MAX20076ATCC/V+ application, or MAX20076ATCC/V+ equivalent, this page delivers verified electrical specs, validated pin functions, confirmed automotive-grade thermal/EMI features, and real-world design constraints including dropout operation at 99% duty cycle and 40V load-dump tolerance.
Technical Context
The MAX20076ATCC/V+ implements current-mode control with integrated high-side (300–550mΩ) and low-side (200–350mΩ) MOSFETs, enabling stable regulation down to 1V output directly from automotive battery inputs without cascaded stages. Its 20ns minimum on-time supports >10:1 input-to-output voltage ratios at 2.1MHz switching.
It operates exclusively in Forced-PWM (FPWM) mode-SYNC must be tied to BIAS-and includes spread-spectrum modulation (±6%) via SPS pin to reduce EMI. Protection includes 1.9A peak current limit, thermal shutdown at 175°C, and open-drain PGOOD with 93.5% rising threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.5V to 36V - supports cold-crank (3.5V) and 40V load-dump transients without external clamping |
| Output Current | 1.2A continuous - sufficient for powering ADAS sensors, infotainment SoCs, or CAN transceivers |
| Output Voltage Range | 1V to 3.6V - set externally via resistor divider; not fixed; enables custom LDO replacement |
| Switching Frequency | 2.1MHz (typ) - enables use of 4.7µH inductor and small 4.7µF input / 22µF output ceramic capacitors |
| Minimum On-Time | 20ns - allows direct 12V→1.2V conversion at full frequency without pulse-skipping |
| FB Accuracy | ±1.5% - ensures tight output regulation across temperature and line/load variations for precision analog rails |
| Duty Cycle Max | 99% - sustains regulation during automotive dropout conditions (e.g., 5.5V input → 5V output) |
Pinout & Package
Package: 12-pin TDFN (3mm × 3mm), exposed pad (EP), RoHS-compliant, automotive-grade (AEC-Q100 qualified).
| 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 | Accepts 0–36V logic; no internal pullup/pulldown; enables microcontroller or KEY-line control |
| 3 BST | Bootstrap supply | Requires 0.1µF capacitor to LX; sustains high-side gate drive during 99% duty-cycle dropout |
| 4 SUP | Main input supply | 3.5–36V input; requires 4.7µF ceramic decoupling adjacent to pin for high-frequency noise suppression |
| 5 LX | Switch node | Connects to 4.7µH inductor; internal clamp diodes to PGND/AGND/SUP require careful layout to avoid overstress |
| 6 PGND | Power ground | High-current return path for LX, SUP, and OUT; must be connected to EP and isolated from AGND except at single point |
| 7 AGND | Analog ground | Reference for FB, BIAS, SYNC, SPS; connects to EP only via single-point star ground near output capacitor |
| 8 FB | Feedback input | Senses output via resistor divider; 1V reference with ±1.5% accuracy; connect to BIAS only for fixed outputs (not applicable here) |
| 9 OUT | Output voltage sense | Regulated output node; bypassed with 22µF ceramic to PGND; used as feedback source for external divider |
| 10 BIAS | Internal 5V bias rail | Supplies internal circuitry; requires ≥1µF ceramic to AGND; used as pullup for PGOOD and SYNC |
| 11 SYNC | Oscillator control | Tie to BIAS to enable FPWM mode; internal 1MΩ pulldown; not used for external clock sync in this variant |
| 12 PGOOD | Open-drain power-good | Active-high signal pulled low when VOUT < 93% nominal; requires external 20kΩ pullup to BIAS or system rail |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX20076ATCB/V+ | Fixed 3.3V output; same 1.2A rating, package, and 2.1MHz frequency; no external FB divider required | Used where 3.3V is standard rail (e.g., USB PHY, CAN transceiver); eliminates RFB1/RFB2 selection effort | Select MAX20076ATCB/V+ only if fixed 3.3V suffices; MAX20076ATCC/V+ offers flexibility for nonstandard rails like 1.8V or 2.5V. |
| LM61480RQWR | 3.5–36V input, 1.2A, 2.1MHz, but uses voltage-mode control; 35ns min on-time; no spread-spectrum; different pinout | Requires external compensation; lacks PGOOD threshold adjustability and AEC-Q100 qualification | Choose LM61480RQWR only for cost-sensitive non-automotive designs where AEC-Q100 and EMI certification are not required. |
Compared with MAX20076ATCB/V+, the MAX20076ATCC/V+ trades fixed-output simplicity for programmable 1V–3.6V flexibility; versus LM61480RQWR, it provides automotive qualification, tighter FB accuracy, and integrated EMI reduction-making it superior for safety-critical or emission-regulated deployments.

FAQ
What output voltage range does the MAX20076ATCC/V+ support?
The MAX20076ATCC/V+ supports an externally programmed output voltage range of 1V to 3.6V using a resistor divider from OUT to FB to AGND. It does not support fixed outputs or voltages above 3.6V-unlike MAX20076ATCA/V+ (5V) or MAX20076ATCB/V+ (3.3V). The FB pin has a 1V reference with ±1.5% accuracy, enabling precise regulation across temperature and line conditions.
Is the MAX20076ATCC/V+ qualified for automotive applications?
Yes, the MAX20076ATCC/V+ is AEC-Q100 Grade 1 qualified (-40°C to +125°C ambient), features 40V load-dump tolerance, and operates over a 3.5V–36V input range-meeting key requirements for engine control units, ADAS cameras, and body control modules. Its exposed-pad TDFN package and thermal shutdown (175°C) further ensure robustness in automotive under-hood environments.
Does the MAX20076ATCC/V+ support skip mode or DCM operation?
No-the MAX20076ATCC/V+ is specified for Forced-PWM (FPWM) operation only. The datasheet explicitly states "this device is only recommended for FPWM operation." Skip mode is supported only in the 'D' variants (e.g., MAX20076D), which have different quiescent current and light-load behavior. Using MAX20076ATCC/V+ in discontinuous conduction mode may cause instability or undefined timing behavior.
What is the minimum on-time specification for the MAX20076ATCC/V+?
The MAX20076ATCC/V+ has a guaranteed minimum on-time of 20ns, as confirmed in the Electrical Characteristics table under "Minimum On-Time tON_V." This enables high input-to-output voltage ratios (e.g., 12V→1.2V) at its fixed 2.1MHz switching frequency without pulse-skipping, preserving ripple performance and EMI predictability in automotive applications.
How is power-good functionality implemented on the MAX20076ATCC/V+?
The MAX20076ATCC/V+ provides an open-drain PGOOD output that pulls low when VOUT falls below 93% of its nominal value and goes high-impedance when VOUT exceeds 93.5%. It requires an external 20kΩ pullup resistor to BIAS or another system rail. This signal is used for power sequencing-ensuring downstream ICs only initialize after stable regulation is achieved.
