Analog Devices Inc./Maxim Integrated MAX20416ATGF/V+T

Overview

The MAX20416ATGF/V+T from Maxim Integrated is a dual-output, synchronous step-down DC-DC converter designed for automotive power rails. It delivers up to 3A per channel from a 3.0V–5.5V input, supports factory-programmed 1.175V/1.8V outputs, achieves ±1.5% output voltage accuracy over temperature and load, operates at 2.2MHz fixed-frequency PWM or skip mode, and is AEC-Q100 qualified for instrument cluster and infotainment systems.

For engineers reviewing the MAX20416ATGF/V+T datasheet, MAX20416ATGF/V+T pinout, MAX20416ATGF/V+T application, or MAX20416ATGF/V+T equivalent, key selection criteria include dual-channel current capability (3A each), programmable spread-spectrum EMI reduction, independent EN/RESET signals, thermal shutdown at 165°C, and 4mm × 4mm TQFN-24 packaging with exposed pad for automotive-grade thermal management.

Technical Context

The MAX20416ATGF/V+T integrates two independent current-mode buck controllers with cycle-by-cycle overcurrent protection and valley-current sensing. Each channel features programmable soft-start (1.25ms or 2.5ms), ±3% undervoltage/overvoltage reset thresholds, and 180° phase-shifted switching between LX1 and LX2 to reduce input ripple.

Its SYNC pin is factory-configured as an input enabling forced-PWM (with external clock or PV tie) or light-load skip mode (open or grounded). The internal oscillator provides 2.2MHz ±3% spread-spectrum operation, and both channels share a common analog ground (GND) and separate power grounds (PGND1/PGND2) for optimal noise isolation.

FAQ

What is the output voltage configuration of the MAX20416ATGF/V+T?

The MAX20416ATGF/V+T has factory-programmed output voltages of 1.175V on OUT1 and 1.8V on OUT2. These values are trimmed during production and do not require external feedback resistors. The device belongs to the MAX20416ATGF/V+ ordering variant, which specifies these exact voltages, soft-start enabled, and SYNC configured as input - all confirmed in the official Maxim Integrated Ordering Information table.

Does the MAX20416ATGF/V+T support synchronization to an external clock?

Yes, the MAX20416ATGF/V+T 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 reduction and multi-device timing alignment. This behavior is explicitly documented in the Synchronization section and Pin Description table of the MAX20416ATGF/V+T datasheet.

What thermal performance can be expected from the MAX20416ATGF/V+T in a four-layer PCB?

In a standard four-layer PCB layout, the MAX20416ATGF/V+T achieves a junction-to-ambient thermal resistance (θJA) of 36°C/W and junction-to-case (θJC) of 3°C/W. These values are measured per JEDEC JESD51-7 and assume proper soldering of the exposed pad to a solid ground plane. The low θJC enables efficient heat transfer to the PCB, supporting continuous 3A operation at +125°C ambient when layout guidelines are followed.

How does the MAX20416ATGF/V+T handle overvoltage and undervoltage conditions?

The MAX20416ATGF/V+T monitors each output independently using precision comparators with ±3% threshold accuracy relative to nominal voltage. When OUT1 or OUT2 falls below 93% (UV) or rises above 107% (OV) of its set point, the corresponding open-drain RESET1 or RESET2 pin asserts low for a fixed 7.4ms timeout period. This behavior is guaranteed across -40°C to +125°C and is validated per AEC-Q100 requirements.

Is the MAX20416ATGF/V+T pin-compatible with other variants in the MAX20416 family?

Yes, all MAX20416 variants - including MAX20416ATGF/V+T - share identical 24-pin TQFN-EP (4mm × 4mm) packaging and pinout. The differences between variants (e.g., MAX20416ATGA/V+, MAX20416ATGE/V+) are limited to factory-programmed parameters such as output voltage, soft-start enable/disable, and SYNC configuration - none affect mechanical or electrical pin compatibility. This allows drop-in replacement within the same package footprint.
