® RT8274 3A, 24V, 400kHz Step-Down Converter General Description The RT8274 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 3A. Current Mode operation provides fast transient response and eases loop stabilization. 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 RT8274 is available in a SOP-8 (Exposed Pad) surface mount package. Ordering Information RT8274 Package Type SP : SOP-8 (Exposed Pad-Option 1) Note : Lead Plating System G : Green (Halogen Free and Pb Free) Richtek products are :  RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020.
