1.3 Specification

Table 1-1 table lists the electrical characteristics of the evaluation module. See the LM25190-Q1 product folder for more information about the device specifications. Efficiency and other performance metrics can change based on operating input voltage, load currents, externally-connected output capacitors, and other parameters. The recommended airflow is 200 LFM when operating.
