The BD9111NV-E2 from ROHM Semiconductor is a high-efficiency, 1-channel synchronous step-down (buck) switching regulator. Designed for power supply applications for LSIs such as DSPs, microcomputers, and ASICs, it can produce a voltage as low as 3.3V from a 5V supply.
Key electrical specifications include an input voltage range of 4.5V to 5.5V, a maximum output current of 2.0A, and a typical output voltage of 3.3V. The device operates at a typical switching frequency of 1MHz. It features integrated Nch and Pch FETs with low ON-resistance (150mΩ and 200mΩ typical, respectively) and utilizes pulse skip control technology for high efficiency across all load ranges. The current mode PWM control system ensures fast transient response.
Additional features include a soft-start function, thermal shutdown, undervoltage lockout (UVLO), and a time-delayed short-circuit protection function. The device also has a shutdown function and a standby current of 0μA typical. It is housed in a compact SON008V5060 package, measuring 5.00mm x 6.00mm, and is designed for surface mounting.
The operating temperature range is -25°C to +105°C. This regulator is suitable for applications requiring efficient voltage conversion and fast load response.
