www.DataSheet4U.com NCP1575 Low Voltage Synchronous Buck Controller with Adjustable Switching Frequency The NCP1575 is a low voltage buck controller.

It provides the control for a DC DC power solution producing an output voltage as low as 0.980 V over a wide current range.

It contains all required circuitry for a synchronous NFET buck regulator using the V2t control method to achieve the fastest possible transient response and best overall regulation.

The NCP1575 operates at a default s
