MaxLinear MXL76508 | Demoboard MXL76508 EVK

Beschreibung

The MxL76508 evaluation kit (EVK) provides a platform to evaluate the features and performance of the MxL76508 synchronous step-down constant on-time (COT) buck converter. The MxL76508 provides a maximum load current rating of 8A with an input voltage range of 3V to 18V. It is packaged in a 3mm×3mm 16-lead QFN.This document provides the EVK schematic (see “EVK Schematic” on page 7), PCB layout (see “EVK PCB Layers” on page 8), and bill of materials (see “EVK Bill of Materials” on page 11). They can help you with your design.For more information, refer to the MxL76508 Data Sheet (286DS). It includes a complete list of the device features, pinout, pin descriptions, typical performance characteristics, and external component calculations. This user manual is intended to be used in conjunction with the data sheet.
