Product details
Overview
MAX20416ATGF/V+ from Maxim Integrated is a dual-output, synchronous step-down DC-DC converter optimized for automotive infotainment and instrument cluster power rails. It delivers up to 3A per channel from a 3.0V–5.5V input, with factory-set outputs of 1.175V (OUT1) and 1.8V (OUT2), ±1.5% output voltage accuracy over load/line/temperature, and 2.2MHz fixed-frequency PWM operation enabling all-ceramic external components.
For engineers reviewing the MAX20416ATGF/V+ datasheet, MAX20416ATGF/V+ pinout, MAX20416ATGF/V+ application, or MAX20416ATGF/V+ equivalent, key selection criteria include AEC-Q100 qualification, dual independent enable/reset pins, spread-spectrum EMI reduction, thermal shutdown at +165°C, and 4mm × 4mm 24-pin TQFN packaging with exposed pad for automotive-grade thermal performance.
Technical Context
The MAX20416ATGF/V+ integrates two current-mode, synchronous buck controllers with independent EN1/EN2 inputs and open-drain RESET1/RESET2 outputs tied to precise undervoltage (93% ±3%) and overvoltage (107% ±3%) thresholds per channel. Its 2.2MHz internal oscillator supports both forced-PWM and skip-mode operation via the SYNC pin, with programmable spread-spectrum modulation (±3%) to suppress radiated emissions.
Each channel features cycle-by-cycle current limiting with four factory-selectable ILIM options (1A–3.6A), soft-start time of 2.5ms (factory-configured), and integrated high-side/low-side MOSFETs with RDS(ON) of 35mΩ/20mΩ (typ) at 3.3V PV. Thermal protection includes automatic recovery after 15°C hysteresis following shutdown at +165°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.0V to 5.5V - Supports direct connection to automotive 3.3V or 5V supply rails without pre-regulation. |
| Output Voltages | 1.175V (OUT1), 1.8V (OUT2) - Factory-preset for SoC core and I/O rail sequencing in infotainment processors. |
| Max Output Current | 3A per channel - Enables single-chip power delivery for dual-rail applications without external current sharing. |
| Switching Frequency | 2.2MHz (±10%) - Allows use of compact 0.47µH inductors and all-ceramic output capacitors (e.g., 47µF). |
| Output Accuracy | ±1.5% over -40°C to +125°C - Ensures stable core voltage under full automotive temperature range without calibration. |
| UV/OV Thresholds | 93% / 107% of nominal output - Provides robust reset signaling for system-level fault detection and safe boot sequencing. |
| Thermal Shutdown | +165°C with 15°C hysteresis - Protects against sustained overload while enabling automatic recovery during transient thermal events. |
Pinout & Package
MAX20416ATGF/V+ is housed in a lead(Pb)-free, RoHS-compliant 4mm × 4mm 24-pin TQFN package (T2444+4C) with exposed thermal pad connected to GND. The package supports JEDEC-standard reflow and achieves θJA = 36°C/W on a 4-layer PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | RESET2, RESET1 | Open-drain fault indicators - Assert low when respective output falls below 93% or rises above 107% of nominal; 7.4ms hold time ensures reliable system reset timing. |
| 5, 6 | EN1, EN2 | Independent active-high enables - Allow staggered startup or dynamic channel disable; 1.0V threshold with 100mV hysteresis rejects noise on automotive power domains. |
| 7, 24 | OUT1, OUT2 | Feedback inputs - Accept resistor-divider networks for adjustable outputs or connect directly to VOUT for fixed-voltage operation. |
| 9, 22 | LX1, LX2 | Switch-node connections - Drive external 0.47µH inductors; require tight layout to PGND1/PGND2 to minimize EMI and switching losses. |
| 10, 21 | PV1, PV2 | Channel-specific power inputs - Each requires local 4.7µF ceramic decoupling to PGND1/PGND2 to suppress high-frequency ripple. |
| 11 | SYNC | Factory-configured input - Logic-high enables forced-PWM mode; floating or logic-low activates skip mode for light-load efficiency. |
| 13, 17, 19, 20, 23 | GND / PGND1 / PGND2 | Common ground reference - All must be connected to a low-impedance ground plane; exposed pad is thermally critical and must be soldered to GND. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent buck regulators | Enables simultaneous 1.175V/1.8V power delivery with separate enable, reset, and feedback paths - eliminates need for two discrete converters in space-constrained automotive modules. |
| AEC-Q100 Grade-1 qualification | Validated for operation from -40°C to +125°C ambient - meets automotive reliability requirements for instrument clusters and head units without derating. |
| Spread-spectrum frequency modulation | ±3% pseudorandom modulation of 2.2MHz clock - reduces peak radiated EMI by >10dB compared to fixed-frequency operation, easing EMC compliance. |
| Integrated MOSFETs with low RDS(ON) | 35mΩ/20mΩ (pMOS/nMOS) at 3.3V - achieves >90% efficiency at 3A load while eliminating external switch losses and layout complexity. |
| Programmable soft-start | Factory-set 2.5ms ramp time - limits inrush current during cold crank or battery recovery, preventing input voltage droop that could reset microcontrollers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output automotive buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4436-AEC1 | Single 3A buck with external compensation; no dual-output or integrated RESET outputs. | Requires two devices plus external sequencing for dual-rail systems; lacks per-channel UV/OV monitoring. | Choose when cost-per-amp is prioritized over integration and fault reporting capability. |
| TPS650362-Q1 | Triple-output PMIC (2× buck + LDO); fixed 1.2V/1.8V outputs; no spread-spectrum or SYNC-controlled skip mode. | Supports additional low-current rails but offers less flexibility in output voltage selection and EMI control than MAX20416ATGF/V+. | Choose when needing three regulated outputs in one package and fixed 1.2V/1.8V matches system requirements exactly. |
Compared with MPQ4436-AEC1 and TPS650362-Q1, the MAX20416ATGF/V+ uniquely combines dual 3A synchronous buck regulation, per-channel RESET signaling, spread-spectrum EMI suppression, and AEC-Q100 qualification in a single 4mm × 4mm package - making it optimal for next-generation automotive displays requiring high integration and stringent EMC compliance.

FAQ
What is the output voltage configuration of the MAX20416ATGF/V+?
The MAX20416ATGF/V+ has factory-preset output voltages: 1.175V for OUT1 and 1.8V for OUT2. These values are fixed and not resistor-adjustable. The device does not require external feedback resistors for these outputs, simplifying layout and reducing BOM count. This configuration is explicitly defined in the Ordering Information/Selector Guide for the MAX20416ATGF/V+ variant.
Does the MAX20416ATGF/V+ support synchronization to an external clock?
Yes, the MAX20416ATGF/V+ supports external clock synchronization via its SYNC pin, which is factory-configured as an input. When driven with a 1.8MHz–2.6MHz external clock signal, the internal oscillators lock to that frequency, enabling deterministic EMI profile alignment across multiple converters in the same system. This capability is confirmed in the Synchronization section of the datasheet.
What thermal performance can be expected from the MAX20416ATGF/V+ in a 4-layer PCB design?
In a standard 4-layer PCB layout, the MAX20416ATGF/V+ achieves a junction-to-ambient thermal resistance (θJA) of 36°C/W. With a maximum junction temperature of +150°C and ambient temperature of +85°C, this allows continuous 3A operation per channel without thermal derating. The exposed pad must be fully soldered to a thermal plane for this performance to be realized.
How does the MAX20416ATGF/V+ handle overcurrent conditions?
The MAX20416ATGF/V+ implements cycle-by-cycle current limiting with four factory-set thresholds (1A–3.6A). For the MAX20416ATGF/V+, the threshold is set to 3A per channel. During overload, the high-side MOSFET remains on until inductor current reaches the limit, then the low-side MOSFET turns on to discharge the inductor - repeating until fault clears. This prevents damage during short circuits while maintaining regulation under transient overloads.
Is the MAX20416ATGF/V+ pin-compatible with other variants in the MAX20416 family?
Yes, all MAX20416 variants-including MAX20416ATGF/V+-share identical 24-pin TQFN packaging, pinout, and footprint (T2444+4C). Differences are limited to factory-programmed parameters (output voltages, soft-start time, SYNC configuration), meaning PCBs designed for any MAX20416 variant can accommodate the MAX20416ATGF/V+ without layout changes.
