NR263S Datasheet (SANKEN) - Synchronous Rectification Buck Converter

NR263S, Synchronous Rectification Buck Converter

The NR263S is synchronous rectification buck converter IC with built-in power MOSFET.

In light load, the IC operates with the pulse skip mode to improve the efficiency.

By using the peak current control method, the IC stably operates with a low ESR capacitor such as a ceramic capacitor.

The IC has t
