STEVAL-L6981NDR

STEVAL-L6981NDR is based on the L6981NDR synchronous monolithic step-down regulator delivering up to 1.5A DC. Its wide input voltage range makes the solution suitable for a broad range of applications. The device implements peak current mode architecture in a 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 controlled output voltage ripple, making the device extremely suitable for battery-powered applications. LNM makes the switching frequency constant and minimizes the output voltage ripple overload current range, meeting the specification for noise sensitive applications. The EN pin manages the enable/disable function. The typical shutdown current is 2μA when disabled.
