The STMicroelectronics B5973D is an adjustable positive buck switching regulator IC designed for high-performance applications. This component delivers a continuous output current of 2A and operates with a switching frequency of 250kHz. Featuring a robust design, it supports input voltages ranging from 4V to 36V, with an adjustable output voltage min/fixed of 1.235V and a maximum output voltage of 35V. The B5973D is housed in an 8-SOIC (0.154"", 3.90mm Width) Exposed Pad package, suitable for surface mounting. Its AEC-Q100 qualification and operation over an extended temperature range of -40°C to 150°C (TJ) make it ideal for demanding automotive environments and industrial control systems. The device employs a non-synchronous buck topology.
