The STMicroelectronics L4972A is a monolithic integrated circuit designed for step-down (buck) switching regulator applications. This adjustable output device operates with input voltages ranging from 15V to 50V, capable of delivering up to 2A of output current. The L4972A features an adjustable output voltage, with a minimum fixed output of 5.1V and a maximum adjustable output up to 40V. Its switching frequency is adjustable between 100kHz and 200kHz. The device is packaged in a 20-DIP (0.300", 7.62mm) configuration, suitable for through-hole mounting. It is commonly utilized in industrial automation, consumer electronics, and power supply systems requiring efficient voltage conversion. The operating temperature range for the L4972A is -40°C to 150°C (TJ). This component is a single-output, non-synchronous buck regulator.
