The RT8256 is an as high voltage buck converter that can support the input voltage range from 4.75V to 22V and the output current can be up to 2A. Current Mode operation provides fast transient response and eases loop stabilization.<br />The chip provides protection functions such as cycle-by-cycle current limiting and thermal shutdown protection. In shutdown mode, the regulator draws 25μA of supply current. The RT8256 is available in a SOP-8 surface mount package.</p>
