STMicroelectronics STEVAL-L6981CDR Evaluation Board

STMicroelectronics STEVAL-L6981CDR Evaluation Board is based on the L6981CDR synchronous monolithic step-down regulator capable of delivering up to 1.5A DC. The L6981 has a wide input voltage range that makes the device suitable for a broad range of applications. The device implements peak current mode architecture in an SO 8L package with internal compensation to minimize design complexity and size. The L6981 is available in low consumption mode (LCM) and low noise mode (LNM) versions. LCM maximizes efficiency at light load with a controlled output voltage ripple, making the device extremely suitable for battery-powered applications.
