The ROHM Semiconductor BD9B400MUV-E2 is a high-performance step-down (buck) DC DC switching regulator. Designed for efficient power conversion, it features a maximum output current of 4A and an adjustable output voltage starting from 2.7V. The device operates at switching frequencies of 1MHz or 2MHz, allowing for flexible design choices and potentially smaller external components.
This regulator is housed in a compact 16-VFQFN exposed pad package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C (TA), making it suitable for a variety of environmental conditions. The synchronous rectifier design enhances efficiency.
Key electrical characteristics include its step-down topology and positive output configuration. The BD9B400MUV-E2 is designed for applications requiring reliable and efficient voltage regulation in a small form factor.
