Product details
Overview
The MAX20076ATCC/VY+ from Analog Devices is a 36V, 1.2A 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 MAX20076ATCC/VY+ datasheet, MAX20076ATCC/VY+ pinout, MAX20076ATCC/VY+ application, or MAX20076ATCC/VY+ equivalent, key selection criteria include its AEC-Q100 qualification, 3.5V–36V input range, 40V load-dump protection, side-wettable 12-pin TDFN package, and FPWM-only operation mode with spread-spectrum EMI reduction.
Technical Context
This current-mode-controlled buck regulator operates exclusively in forced-PWM (FPWM) mode - no skip-mode or PFM - ensuring constant 2.1MHz switching across all loads to minimize EMI and simplify filtering. Its 20ns minimum on-time enables direct step-down from automotive battery (e.g., 12V/24V) to sub-3V rails like 1.8V or 1.2V without cascaded conversion.
The device integrates high-side (300–550mΩ) and low-side (200–350mΩ) MOSFETs, features internal 2.5ms soft-start, ±2% output accuracy at fixed voltages (not applicable here), ±1.5% FB accuracy for adjustable outputs, and robust protection including 40V load-dump tolerance, thermal shutdown at 175°C, and hiccup-mode overcurrent response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.5V to 36V - supports cold-crank (3.5V) and load-dump (40V transient) conditions in automotive systems |
| Output Current | 1.2A continuous - sufficient for powering microcontrollers, sensors, and CAN transceivers from single-stage conversion |
| Switching Frequency | 2.1MHz (typ) - enables use of small 4.7µH inductor and 22µF ceramic output capacitor, avoiding AM-band interference |
| Minimum On-Time | 20ns - allows direct 12V→1.2V (10% duty cycle) or 24V→1.8V (7.5% duty cycle) regulation without pulse-skipping |
| Output Voltage Range | 1V to 3.6V (externally set via FB divider) - optimized for low-voltage logic rails including I/O, core, and interface supplies |
| Protection Features | 40V load-dump rating, 99% dropout duty cycle, thermal shutdown (175°C), and hiccup-mode overcurrent limiting |
| Operating Temperature | −40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood and body-control module deployment |
Pinout & Package
MAX20076ATCC/VY+ uses a 3mm × 3mm, 12-pin side-wettable TDFN package (package code TD1233Y+2C) with exposed pad (EP) for thermal dissipation. The EP must be soldered to PGND on PCB for reliable thermal performance in automotive environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SPS | Spread-spectrum enable | Logic-high enables ±6% frequency modulation 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 - enables direct connection to automotive KEY or CAN inhibit signals |
| 3 BST | Bootstrap supply for high-side gate driver | Requires 0.1µF ceramic capacitor to LX; critical for maintaining high-side FET gate charge during 99% duty-cycle dropout operation |
| 4 SUP | Main input supply | 3.5V–36V input; requires 4.7µF ceramic decoupling capacitor placed 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 exceeding power dissipation limits |
| 6 PGND | Power ground return | Low-impedance path for high-current/high-frequency switching currents; must be connected to EP and output capacitor negative terminal |
| 7 AGND | Analog ground reference | Return for quiet analog signals (FB, SYNC, SPS); must tie to PGND at single point - preferably at output capacitor cathode |
| 8 FB | Feedback voltage sense | Connects to resistor divider (RTOP/RBOT) for 1V–3.6V output setting; ±1.5% accuracy enables tight regulation without trimming |
| 9 OUT | Regulated output | Bypassed with 22µF ceramic capacitor to PGND; serves as both power output and voltage-sense point for feedback loop |
| 10 BIAS | Internal 5V bias supply | Provides regulated 5V for internal circuitry; requires ≥1µF ceramic capacitor to AGND; used as pullup for PGOOD |
| 11 SYNC | Oscillator synchronization input | Connect to BIAS to enable internal 2.1MHz clock; accepts external 1.7–2.6MHz clock for system-level timing alignment |
| 12 PGOOD | Open-drain power-good indicator | Active-high signal asserting when VOUT ≥ 93.5% of target; requires external 20kΩ pullup to BIAS or system rail for sequencing |
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 |
|---|---|---|---|
| MAX20076ATCC/V+ | Same electrical specs and pinout, but uses standard (non-side-wettable) TDFN package (TD1233+2C) | Lacks AOI-compatible solder joints; suitable for non-automotive or lower-reliability industrial use | Select MAX20076ATCC/V+ only if AOI is not required and cost sensitivity outweighs automotive traceability needs. |
| LM61460QWRNRQ1 | 3.5V–36V, 6A, 2.1MHz, AEC-Q100 - higher current, same frequency, but larger 16-pin WQFN package and different pinout | Designed for higher-power domains (e.g., ADAS domain controllers); not pin-compatible; requires layout redesign | Choose LM61460QWRNRQ1 only when >1.2A output or dual-phase capability is needed - not a drop-in replacement. |
Compared with MAX20076ATCC/V+, the MAX20076ATCC/VY+ adds side-wettable leads for automated optical inspection - essential for automotive Tier-1 production - while maintaining identical electrical performance and footprint. The LM61460QWRNRQ1 offers higher current but demands PCB redesign and lacks the 20ns on-time advantage for ultra-low-VOUT applications.

FAQ
What is the maximum input voltage transient the MAX20076ATCC/VY+ can withstand?
The MAX20076ATCC/VY+ is rated for 40V load-dump transients per ISO 7637-2 Pulse 5a, enabling direct connection to automotive 12V and 24V battery rails without external TVS clamping. This rating is validated under AEC-Q100 stress testing and applies across the full −40°C to +125°C operating temperature range. The device remains functional during the transient and resumes regulation once voltage returns within 3.5V–36V normal operating range.
Can the MAX20076ATCC/VY+ operate in pulse-frequency modulation (PFM) or diode-emulation mode?
No - the MAX20076ATCC/VY+ is designed exclusively for forced-PWM (FPWM) operation. Datasheet Section "Oscillator/Synchronization and Efficiency" explicitly states "only Forced-PWM operation is recommended." Attempting PFM or skip-mode will result in unstable regulation, excessive output ripple, and potential failure to meet AEC-Q100 lifetime requirements. SYNC must be tied to BIAS to enable internal clock operation.
What is the purpose of the SPS pin on the MAX20076ATCC/VY+ and how should it be configured?
The SPS (Spread-Spectrum) pin on the MAX20076ATCC/VY+ enables ±6% frequency modulation of the 2.1MHz internal oscillator to reduce peak radiated EMI emissions. To activate spread spectrum, drive SPS to logic-high (≥1.4V); leave unconnected or tie to AGND to disable. The internal 1MΩ pulldown ensures safe default-disable state. Spread spectrum operates only during internal clock mode - it does not affect externally synchronized operation.
Does the MAX20076ATCC/VY+ support output voltages below 1V or above 3.6V?
No - the MAX20076ATCC/VY+ is factory-configured for 1V to 3.6V output via external resistor-divider only, as specified in the Ordering Information table. Attempts to set VOUT < 1V risk violating FB pin voltage limits (−0.3V to VBIAS + 0.3V), while >3.6V exceeds the validated range and may cause regulation inaccuracy or instability. For 5V or 3.3V fixed outputs, select MAX20076ATCA/V+ or MAX20076ATCB/V+ respectively.
How is thermal performance affected by the side-wettable package (VY+) versus standard TDFN (V+)?
The side-wettable TDFN package (VY+) of the MAX20076ATCC/VY+ provides identical thermal resistance (θJA = 41°C/W, θJC = 9°C/W on 4-layer board) to the standard TDFN (V+) variant because both share the same die, exposed pad area, and copper thermal vias. The side-wettable feature improves solder joint inspection reliability - not thermal conduction - and has no impact on junction-to-ambient or junction-to-case metrics under identical PCB layout and copper pour conditions.
