General Description
The RT8265GSP is an asynchronous high voltage buck converter that can support the input voltage range from 4.75V to 24V and the output current can be up to 3A. The IC provides a Feed-forward Voltage Mode operation to achieve the goal of fast line transient response. The RT8265GSP also provides adjustable soft-start to be a flexible solution for customers.
The chip provides protection functions such as cycle-bycycle current limiting and thermal shutdown protection. In shutdown mode, the regulator draws 25μA of supply current. The RT8265GSP is available in a SOP-8 (Exposed Pad) surface mount package.
