ROHM Semiconductor USA, LLC 4.0-5.5V 1.2A 1ch Buck converter BD8966FVM

The BD8966FVM is a synchronous buck converter designed by ROHM Semiconductor, capable of operating within an input voltage range of 4.0V to 5.5V and delivering a maximum output current of 0.8A. It features a wide output voltage range from 1.0V to 2.5V, making it suitable for various low-voltage applications. The device employs a current mode PWM control system, which ensures fast transient response to load changes and high efficiency across all load ranges due to its integrated N-channel and P-channel FETs. Key specifications include a typical switching frequency of 1MHz, a standby current of 0OºA, and an operating temperature range from -25¬8C to +85¬8C. The BD8966FVM also incorporates several protection features, including thermal shutdown, under-voltage lockout (UVLO), and short-circuit current protection with a time delay function. The device is packaged in a compact MSOP8 format, measuring 2.90 mm x 4.00 mm x 0.90 mm, making it suitable for space-constrained designs. This buck converter is ideal for powering LSIs, including DSPs, microcomputers, and ASICs.
