Beschreibung
The EXAR XRP76XX Evaluation kit is a fullyassembled and tested surface-mount PCB thatdemonstrates the XRP7664, XRP7665,XRP7674 and XRP7675 synchronous buckregulators. The current-mode switchingregulator generates a preset 3.3V output witha load of up to 2A (XRP7664, XRP7674) and3A (XRP7665, XRP7675).The EVB kit requires a single input voltage VIN source if EN is tied to VIN via jumper J1 (default setting as supplied from EXAR). If J1 is set to EN=EXT position then a logic-levelsignal is required at EN pin in order to turn theregulator on and off.
