RT8289
5A, 32V, 500kHz Step-Down Converter
General Description
The RT8289 is a step-down regulator with an internal Power
MOSFET. It achieves 5A of continuous output current over
a wide input supply range with excellent load and line
regulation. Current mode operation provides fast transient
response and eases loop stabilization.
The RT8289 provides protections such as cycle-by-cycle
current limiting and thermal shutdown. In shutdown mode,
the regulator draws 25μA of supply current.
The RT8289 requires a minimum number of external
components, to provide a compact solution.
The RT8289 is available in a SOP-8 (Exposed Pad)
package.
