STMicroelectronics A6983 DC-DC Converter, 38V dc/ 3A Output, 3.5 → 38 V dc Input, Surface Mount, +150°C Max Temp

The STMicroelectronics Synchronous monolithic step-down regulator capable of delivering up to 3 A DC to the load. The wide input voltage range makes the device suitable for a broad range of applications. The step-down regulator is based on peak current mode architecture and is packaged in a QFN16 (3 x 3 mm) with internal compensation thus minimizing design complexity and size. The “Low Consumption Mode” (LCM) is designed for applications active during car parking, so it maximizes the efficiency at the light-load with the controlled output voltage ripple. The “Low Noise Mode” (LNM) makes the switching frequency constant and minimizes the output voltage ripple overload current range, which meets the low noise application specification, such as for car audio.
