The L6981NDR is an integrated synchronous step-down switching voltage regulator with 38 V, 1.5 A output current, designed and manufactured by STMicroelectronics. It features low quiescent current operation, excellent power conversion, and high efficiency over a wide input voltage range. Its current-mode control also allows it to have a fast transient response and stable operation across varying loads and regulations. The device integrates an internal power switch, allowing it to operate in a completely self contained, non isolated topology and can be effectively employed in battery-powered applications, where low quiescent current, light load efficiency, and high reliability are key performance indicators.
