L6982N33DR

L6982N33DR is a synchronous monolithic step-down converter with 20µA quiescent current. The wide input voltage range makes the device suitable for a broad range of applications. This 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. Application includes designed for 24V buses industrial power systems, 24V battery powered equipment, decentralized intelligent nodes, sensors and always-on applications, low noise applications, smart meters, and robot cleaner.
