STMicroelectronics A5974D is a high-efficiency, adjustable output buck switching regulator designed for automotive applications. This device operates from a 4V to 36V input range, delivering up to 2.5A output current. The output voltage is adjustable from 1.235V up to 35V, with a fixed internal reference of 1.235V. Featuring a standard buck topology and a switching frequency of 250kHz, it is well-suited for power conversion in automotive infotainment, lighting, and powertrain control systems. The A5974D is qualified to AEC-Q100 and comes in an 8-HSOP-EP package with an exposed pad for enhanced thermal performance. Its surface mount capability and operating temperature range of -40°C to 150°C (TJ) ensure robust operation in demanding environments. This STMicroelectronics regulator provides a single positive adjustable output.
