NR264S - Buck Converter

Description

The NR264S 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.

Light Load High Efficiency Synchronous Rectification Buck Converter IC NR264S Data Sheet Description The NR264S 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 the various protections such as the overcurrent protection, the undervoltage lockout, and the thermal shutdown. The IC achieves the switching regulator circuit with few components and small mounting area.
