ROHM Semiconductor USA, LLC Voltage Regulators - DC DC Switching Regulators BD8967FVM-TR

The BD8967FVM-TR is a synchronous buck converter designed for high efficiency in step-down voltage regulation. It operates with an input voltage range of 4.5V to 5.5V and can output a regulated voltage of 3.3V with a maximum output current of 0.8A. The device features a current mode PWM control system, which enables fast transient response to load changes, making it suitable for applications requiring stable power supply, such as LSI, DSP, microcomputers, and ASICs. Key specifications include a typical switching frequency of 1MHz, low ON-resistance values of 350m,Ѷ for the P-channel FET and 250m,Ѷ for the N-channel FET, and a standby current of 0OºA. The operating temperature range is from -25¬8C to +85¬8C. Additional protective features include thermal shutdown, under-voltage lockout (UVLO), short-circuit protection with a time delay, and a soft-start function to minimize inrush current during startup. The device is packaged in an MSOP8 format, measuring 2.90 mm x 4.00 mm x 0.90 mm.
