FAQ

What is the primary function of the MAX20048EVKIT#?

The MAX20048EVKIT# is a fully assembled evaluation kit for the MAX20048 buck-boost controller IC. It enables functional verification, performance characterization, and design-in support for automotive power applications. The MAX20048EVKIT# includes all necessary components, test points, and proven layout to validate input range, output regulation, PGOOD behavior, and EMI performance of the MAX20048 in real-world conditions.

Does the MAX20048EVKIT# support output voltage programming?

Yes, the MAX20048EVKIT# supports both fixed 5V output and programmable output from 4V to 25V using external resistor dividers on the FB pin. This flexibility allows the MAX20048EVKIT# to emulate various downstream rail requirements-such as USB power (5V), display bias (12V), or sensor interfaces (3.3V/5V)-without hardware modification.

Can the MAX20048EVKIT# be synchronized to an external clock?

Yes, the MAX20048EVKIT# includes a SYNCIN terminal that accepts an external clock signal to synchronize the MAX20048's switching frequency. This feature enables noise-sensitive multi-rail systems-like instrument clusters-to avoid beat frequencies and reduce conducted EMI, making the MAX20048EVKIT# suitable for timing-critical automotive subsystems.

What does the PGOOD signal indicate on the MAX20048EVKIT#?

The PGOOD signal on the MAX20048EVKIT# asserts high when the output voltage is within ±2% (9V–18V input) or ±3% (2V–18V input) of the target value and remains stable. It serves as a system-level power-good indicator for microcontroller reset control or downstream enable sequencing, and is accessible via dedicated test point and header on the MAX20048EVKIT# board.

Is spread-spectrum modulation enabled by default on the MAX20048EVKIT#?

Yes, spread-spectrum frequency modulation is enabled by default on the MAX20048EVKIT# to minimize radiated EMI emissions. This feature is implemented per the MAX20048's internal configuration and requires no external components or jumper settings-making the MAX20048EVKIT# compliant-ready for automotive EMC testing without additional tuning.
