The RT8267GS is a high voltage asynchronous buck converter designed for step-down applications, supporting an input voltage range of 4.75V to 22V and capable of delivering an output current of up to 2A. It operates at a fixed switching frequency of 400kHz, providing fast transient response due to its current mode operation. The output voltage is adjustable from 1.222V to 16V, making it versatile for various applications. Key features include a low shutdown current of 25OºA, high efficiency of up to 95%, and built-in protection mechanisms such as cycle-by-cycle current limiting and thermal shutdown. The device is housed in an SOP-8 surface mount package and is RoHS compliant, ensuring it meets environmental standards. Typical applications include battery chargers, DSL modems, and as a pre-regulator for linear regulators.
