Product details
Overview
MAX20416ATGA/V+T from Maxim Integrated is a dual-output, synchronous step-down DC-DC converter for automotive power rails, delivering up to 3A per channel from 3.0V–5.5V input, with factory-preset 1.5V/1.2V outputs, ±1.5% voltage accuracy over load/line/temperature, and AEC-Q100 qualification for instrument cluster and infotainment systems.
For engineers reviewing the MAX20416ATGA/V+T datasheet, MAX20416ATGA/V+T pinout, MAX20416ATGA/V+T application, or MAX20416ATGA/V+T equivalent, this page delivers verified technical context, exact pin functions, automotive-grade thermal and protection specs, and validated alternative options for dual-rail 12V-to-low-voltage conversion in space-constrained modules.
Technical Context
The MAX20416ATGA/V+T integrates two independent current-mode synchronous buck regulators sharing a 2.2MHz fixed-frequency PWM oscillator with ±3% spread-spectrum modulation, enabling all-ceramic output filtering and EMI reduction. Each channel features cycle-by-cycle overcurrent limiting, programmable soft-start (2.5ms), and dedicated open-drain RESET outputs with 7.4ms hold time and ±3% UV/OV threshold accuracy.
Its SYNC pin operates as a factory-configured input enabling forced-PWM (logic-high) or skip mode (open/low), while EN1/EN2 provide independent channel enable control with 1.0V typical threshold and 100mV hysteresis. Thermal shutdown activates at +165°C with 15°C hysteresis, and the IC sustains continuous operation across –40°C to +125°C ambient.
Key Specifications

Pinout & Package
MAX20416ATGA/V+T is housed in a lead(Pb)-free, RoHS-compliant 4mm × 4mm 24-pin TQFN package with exposed thermal pad (EP), optimized for high-power density and low thermal resistance (θJA = 36°C/W on 4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | RESET2, RESET1 | Open-drain reset outputs - assert low when respective output deviates beyond ±3% UV/OV window; require external pull-up for logic signaling |
| 5, 6 | EN1, EN2 | Independent active-high enable inputs - each controls one buck channel; 1.0V threshold enables direct MCU GPIO drive |
| 7, 24 | OUT1, OUT2 | Feedback sense inputs - connect to resistor divider (for adjustable versions) or directly to output cap for fixed-voltage operation |
| 9, 22 | LX1, LX2 | Switch-node terminals - connect to inductor high-side; must be routed with minimal loop area to reduce EMI |
| 10, 21 | PV1, PV2 | Power input supplies for each channel - require local 4.7µF ceramic decoupling to PGND1/PGND2 |
| 11 | SYNC | Factory-configured input - logic-high enables forced-PWM; open/low enables skip mode; accepts 1.8–2.6MHz external clock |
| 13, 17 | PGND, GND | Power and analog ground - all GND/PGND pins must be connected together and tied to EP for optimal thermal performance |
| 18 | PV | Analog supply input - powers internal reference and logic; requires 1µF ceramic cap + 10Ω series resistor for noise isolation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS650362RGER | 2.25MHz dual buck, 2A per channel, no spread spectrum, 1.2V/1.5V fixed outputs, non-AEC-Q100 | Suitable for industrial or consumer infotainment where automotive qualification is not required | Select when cost sensitivity outweighs AEC-Q100 compliance and thermal robustness is less critical |

FAQ
What is the function of the SYNC pin on the MAX20416ATGA/V+T?
The SYNC pin on the MAX20416ATGA/V+T is factory-configured as an input that selects between forced-PWM mode (logic-high or external 1.8–2.6MHz clock) and skip mode (open or logic-low). In forced-PWM, the device operates at a constant 2.2MHz for predictable EMI; in skip mode, switching pauses during light loads to improve efficiency. This behavior is fixed for the MAX20416ATGA/V+T variant and cannot be reconfigured post-manufacture.
Does the MAX20416ATGA/V+T require external feedback resistors for its 1.5V and 1.2V outputs?
No, the MAX20416ATGA/V+T does not require external feedback resistors because its 1.5V (OUT1) and 1.2V (OUT2) outputs are factory-preset. The OUT1 and OUT2 pins are internally connected to the 800mV reference and do not need external dividers. This simplifies layout, improves accuracy, and eliminates resistor tolerance drift-key for automotive reliability in the MAX20416ATGA/V+T design.
How does the MAX20416ATGA/V+T handle overtemperature conditions?
The MAX20416ATGA/V+T activates thermal shutdown at +165°C junction temperature, disabling the bias regulator and step-down controllers until the die cools by 15°C hysteresis. Recovery is automatic and does not require external reset. This protection is fully integrated and tested per AEC-Q100, ensuring safe operation in sealed automotive enclosures where the MAX20416ATGA/V+T may experience sustained high ambient temperatures.
What is the purpose of the separate PV and PV1/PV2 pins on the MAX20416ATGA/V+T?
The PV pin on the MAX20416ATGA/V+T supplies the analog core and reference circuitry, requiring a 1µF ceramic capacitor with a 10Ω series resistor for noise isolation. PV1 and PV2 independently power each buck channel's gate drivers and power switches, each needing a dedicated 4.7µF ceramic capacitor to PGND1/PGND2. This separation minimizes coupling between analog stability and high-current switching noise-critical for maintaining ±1.5% regulation in the MAX20416ATGA/V+T.
Can the MAX20416ATGA/V+T be used in non-automotive applications?
Yes, the MAX20416ATGA/V+T can be used in non-automotive applications such as industrial HMIs or medical displays where its 3A dual outputs, 2.2MHz switching, and ±1.5% accuracy provide value-but its AEC-Q100 qualification, extended temperature range (–40°C to +125°C), and automotive-specific protections (e.g., enhanced UVLO, spread spectrum) are over-spec for most commercial uses. For cost-sensitive non-automotive designs, lower-grade variants like MAX20416ATGD/V+ may be more appropriate than the MAX20416ATGA/V+T.
