STMicroelectronics L6982 Synchronous Step-down Converters

STMicroelectronics L6982 Synchronous Step-down Converters are easy-to-use monolithic regulators capable of delivering up to 2A DC to the load. The L6982 features a wide input voltage range of 3.5V to 38V, making the device suitable for a broad range of applications.

The STM L6982 Synchronous Step-down Converter offers both a low consumption mode (LCM) and a low noise mode (LNM) version. LCM maximizes the efficiency at light-load with a 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 L6982 has a peak current mode architecture and is available in a SO-8L package with internal compensation, minimizing design complexity and size.
