Product Summary

The rt8272gsp 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 rt8272gsp 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 rt8272gsp is available in a SOP-8 (Exposed Pad) surface mount package. The applications of the rt8272gsp include Distributive Power Systems, Battery Charger, DSL Modems, and Pre-regulator for Linear Regulators.
