NCP1573

Low Voltage Synchronous

Buck Controller

The NCP1573 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. The NCP1573−based

solution is powered from 12 V with the output derived from a 2−7 V

supply. It contains all required circuitry for a synchronous NFET buck

regulator using the V ™ control method to achieve the fastest possible

transient response and best overall regulation. NCP1573 operates at a

fixed internal 200 kHz frequency and is packaged in an SO−8.

This device provides Power Good with delay and built−in adaptive

non−overlap.
