Beschreibung

The EXAR XRP7659 Evaluation kit is a fully assembled and tested surface-mount PCB that demonstrates the XRP7659 non-synchronous step-down regulator. The current-mode switching regulator generates a preset 3.3V output with a load of up to 1.5A. The EVB kit requires a single input voltage VIN source, if EN is tied to VIN via jumper J1
