RT8268

RT8268 2A, 24V, 400kHz Step-Down Converter General Description The RT8268 is a high voltage buck converter that can support the input voltage range from 4.75V to 24V and the output current can be up to 2A. Current Mode operation provides fast transient response and eases loop stabilization. The RT8268 also provides adjustable softstart 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 22μA of supply current. The RT8268 is available in the SOP-8 and MSOP-10 (Exposed Pad) surface mount package.
