RT8272GSP 1.2MHz Integrated Circuit IC Chip High Voltage Buck Converter

RT8272GSP 3A, 24V, 1.2MHz Step-Down high voltage buck Converter in SOP8 package
 
 
General Description
The RT8272 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 RT8272 is available in a SOP-8 (Exposed Pad) surface mount package.
