STMicroelectronics A5973D is a high-performance buck switching regulator designed for efficient DC-DC conversion. This adjustable positive output regulator offers a wide input voltage range from 4V to 36V and can deliver up to 2A of output current. Featuring a fixed switching frequency of 250kHz, it employs a non-synchronous buck topology. The A5973D is qualified to AEC-Q100 standards and operates across a temperature range of -40°C to 150°C (TJ), making it suitable for demanding automotive applications. Supplied in an 8-HSOP package with an exposed pad for enhanced thermal management, this device is ideal for power supply designs in automotive infotainment, advanced driver-assistance systems (ADAS), and industrial control systems. The adjustable output voltage can be set as low as 1.235V.
