Analog Devices Inc./Maxim Integrated MAX20416EVKIT#

Overview

MAX20416EVKIT# from Maxim Integrated is an evaluation kit designed to demonstrate the MAX20416 dual-channel synchronous buck PMIC in automotive ADAS and infotainment power systems. It delivers 1.25V/3A on OUT1 and 1.8V/3A on OUT2 from a 3.0V–5.5V input, operates at 2.2MHz, and supports PWM, skip, and external sync modes.

For engineers reviewing the MAX20416EVKIT# datasheet, MAX20416EVKIT# pinout, MAX20416EVKIT# application, or MAX20416EVKIT# equivalent, this board enables rapid validation of dual-output SOC core and I/O rail sequencing, transient response under load step, and SYNC-mode interoperability with system clocks.

Technical Context

The MAX20416EVKIT# implements the full functional interface of the MAX20416 IC, including independent EN1/EN2 controls, RESET1/RESET2 open-drain status outputs, and a shared SYNC input that selects forced-PWM, skip, or externally synchronized operation. Input voltage monitoring and thermal derating behavior are accessible via test points.

It supports all-ceramic output filtering due to its fixed 2.2MHz switching frequency and integrates layout-optimized power stages for low EMI and high PSRR. The PCB includes solder jumpers for mode selection and test-point access to FB1/FB2, VOUT1/VOUT2, and SW1/SW2 nodes.

FAQ

What is the primary function of the MAX20416EVKIT#?

The MAX20416EVKIT# is a fully assembled evaluation kit that demonstrates the MAX20416 dual-output synchronous buck PMIC. It provides validated hardware to evaluate 1.25V/3A and 1.8V/3A regulated outputs, SYNC-mode operation, and RESET signaling-enabling rapid power architecture validation for automotive SoCs before final design sign-off.

Does the MAX20416EVKIT# require external programming or configuration to operate?

No, the MAX20416EVKIT# is preconfigured with fixed 1.25V and 1.8V outputs and requires only a 3.0V–5.5V DC input to operate. Jumper-selectable EN controls and SYNC mode options allow hardware-level configuration without firmware or software tools. The MAX20416EVKIT# does not include microcontrollers or programmable logic.

Can the MAX20416EVKIT# be used to evaluate dynamic load response?

Yes, the MAX20416EVKIT# includes test points for SW1, SW2, VOUT1, VOUT2, and FB1/FB2, enabling oscilloscope-based measurement of load-step transient response, switching node ringing, and loop stability. Its proven PCB layout minimizes parasitic inductance to support accurate high-speed transient analysis of the MAX20416.

What type of input power source is compatible with the MAX20416EVKIT#?

The MAX20416EVKIT# accepts a regulated DC input between 3.0V and 5.5V, such as bench power supplies, automotive battery simulators, or upstream LDO outputs. It is not designed for direct battery connection without overvoltage or reverse-polarity protection, and no onboard surge suppression is included.

Is thermal performance data available for the MAX20416EVKIT# under full 3A load?

Yes, the MAX20416EVKIT# datasheet includes measured junction temperature rise data for both channels operating simultaneously at 3A, 1.25V/1.8V, and 2.2MHz. Thermal images and ambient-to-junction resistance values are provided for still-air and 200LFM airflow conditions, confirming safe operation within automotive ambient limits.
