产品概述

描述

The L6981 is an easy to use synchronous monolithic step-down regulator capable of delivering up to 1.5 A DC to the load. The wide input voltage range makes the device suitable for a broad range of applications. The L6981 is based on a peak current mode architecture and is packaged in an SO8 with internal compensation, thus minimizing design complexity and size. The L6981 is available both in low consumption mode (LCM) and low noise mode (LNM) versions. LCM maximizes the efficiency at light-load with controlled output voltage ripple so the device is suitable for battery-powered applications. LNM makes the switching frequency constant and minimizes the output voltage ripple for light-load operations, meeting the specification for low noise sensitive applications.
The EN pin provides enable/disable functionality. The typical shutdown current is 2 µA when disabled. As soon as the EN pin is pulled up the device is enabled and the internal 1.3 ms soft-start takes place. Pulse-by-pulse current sensing on both power elements implements an effective constant current protection and thermal shutdown prevents thermal run-away.
