Analog Devices Inc./Maxim Integrated MAX42410EVKIT#

Overview

MAX42410EVKIT# from Analog Devices is an evaluation kit designed to characterize the MAX42410 synchronous buck converter IC, supporting input voltages from 4.5V to 36V and delivering up to 10A output current at 1.5MHz switching frequency. It ships with a pre-installed MAX42410AFOB+ (FC2QFN17, 1.5MHz), features adjustable output voltage (0.8V–6V), PGOOD monitoring, SYNC input for external clock synchronization, and a proven PCB layout optimized for thermal and EMI performance in high-current DC-DC applications.

For engineers reviewing the MAX42410EVKIT# datasheet, MAX42410EVKIT# pinout, MAX42410EVKIT# application, or MAX42410EVKIT# equivalent, this board enables rapid validation of MAX42408/MAX42410 buck regulator performance-including efficiency across load conditions, transient response, PGOOD behavior, and SYNC-driven mode control-under real-world 4.5V–36V input and 0.8V–10V output configurations.

Technical Context

The MAX42410EVKIT# implements the MAX42410AFOB+ IC in a fully assembled, tested FC2QFN17-based reference design. It supports dual operating modes-forced PWM (FPWM) and skip mode-selected via the SYNC pin, and provides direct access to critical nodes including LX, BST, EN, FB, PGOOD, and VEA for probing and configuration.

Hardware includes test points for VSUP, VOUT, PGOOD, SYNCOUT, and LX; configurable jumpers (ENABLE, J1, J2); and component options enabling reconfiguration for 400kHz operation (with MAX42410AFOA+) or output voltages up to 10V. Input transient tolerance extends to 42V, and output regulation accuracy is monitored via the PGOOD signal (active-high when VOUT ≥ 93% of nominal).

FAQ

What is the primary function of the MAX42410EVKIT#?

The MAX42410EVKIT# is a fully assembled evaluation board for the MAX42410 synchronous buck converter IC. It enables engineers to validate key performance parameters-including efficiency, transient response, PGOOD behavior, and SYNC-controlled mode switching-across its full 4.5V–36V input and 0.8V–10V output range. The MAX42410EVKIT# includes test points, jumpers, and pre-populated components to simplify lab characterization without custom PCB design.

Which IC variants does the MAX42410EVKIT# support out of the box?

The MAX42410EVKIT# ships with the MAX42410AFOB+ (1.5MHz, FC2QFN17) installed. It also supports the MAX42410AFOA+ (400kHz, FC2QFN17) variant, which can be substituted with corresponding inductor and minor component changes. Both variants share identical pinout and package, allowing direct replacement on the same board footprint without PCB modification.

How is output voltage adjusted on the MAX42410EVKIT#?

Output voltage on the MAX42410EVKIT# is set by resistor divider R7/R8 per the equation R7 = R8 × [(VOUT/VFB) − 1], where VFB = 0.8V (typ). The default 3.3V setting uses R7 = 49.9kΩ and R8 = 15.8kΩ. To change VOUT, remove R5 and install appropriate resistors at R7 and R8 positions; C16 (47pF) must also be selected per the MAX42408/MAX42410 datasheet's CFF table.

What does the PGOOD signal indicate on the MAX42410EVKIT#?

On the MAX42410EVKIT#, the PGOOD signal is an open-drain output that goes high (pulled up via J2) when the regulated output voltage remains within ±7% of its nominal value. It asserts low if VOUT drops below 93% of the target-providing precise, real-time feedback for system power sequencing and fault detection during dynamic load testing.

Can the MAX42410EVKIT# operate in forced PWM mode, and how is it enabled?

Yes, the MAX42410EVKIT# supports forced PWM (FPWM) mode across all load conditions. This is enabled by configuring jumper J1 to pins 1–2 (SYNC pulled high), overriding the default skip-mode behavior. In FPWM mode, the MAX42410 maintains constant switching frequency and reduced output ripple-critical for noise-sensitive applications like data acquisition and RF subsystems.
