NCP1573
Low Voltage Synchronous
Buck Controller
The NCP1573 is a low voltage buck controller. It provides the
control for a DC鈥揇C power solution producing an output voltage as
low as 0.980 V over a wide current range. The NCP1573鈥揵ased
solution is powered from 12 V with the output derived from a 2鈥? V
supply. It contains all required circuitry for a synchronous NFET buck
regulator using the V

餂?/div>
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鈥?.
This device provides Power Good with delay and built鈥搃n adaptive
non鈥搊verlap.
