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 V2 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.
