NCP5230

Precise Low Voltage

Synchronous Buck

Controller with Power

Saving Mode

http://onsemi.com

The NCP5230 is a simple single phase solution with differential

phase current sensing, power saving operation, and gate drivers to

provide accurately regulated power.

MARKING

DIAGRAMS

The adaptive non overlap gate drive and power saving operation

circuit provide a low switching loss and high efficiency solution for

server, notebook, and desktop systems. A high performance

operational error amplifier is provided to simplify compensation of the

system. The NCP5230 features also include soft−start sequence,

accurate overvoltage and over current protection, UVLO for VCC and

VCCP, and thermal shutdown.
