General Description

The RT8279 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.

For protection, the RT8279 provides cycle-by-cycle current

limiting and thermal shutdown protection. An adjustable

soft-start reduces the stress on the input source at

startup. In shutdown mode, the regulator draws only 25μA

of supply current.

The RT8279 requires a minimum number of readily

available external components, providing a compact

solution. The RT8279 is available in the SOP-8 (Exposed

Pad) package
