Quality Control: Learn More
Rohm Semiconductor's BD9011EKN-E2 is a highly efficient, synchronous buck (step-down) DC-DC controller designed for demanding power management applications. This device features a 300kHz switching frequency and supports a wide input voltage range of 3.9V to 30V, making it suitable for automotive, industrial, and consumer electronics power systems. The BD9011EKN-E2 offers advanced control features including Enable, Frequency Control, and Soft Start for precise power sequencing and reduced inrush current. Its architecture supports multiple outputs and a single output phase with a positive output configuration. The controller is packaged in a 36-HQFNV (6.2x6.2) surface-mount package, supplied on tape and reel. The integrated synchronous rectifier enhances efficiency by minimizing conduction losses.
