NCP1570
Low Voltage Synchronous
Buck Controller
The NCP1570 is a low voltage buck controller. It provides the
control for a DC–DC power solution producing an output voltage as
low as 0.985 V over a wide current range. The NCP1570–based
solution is powered from 12 V with the output derived from a 5 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. The NCP1570 operates
at a fixed internal 200 kHz frequency and is packaged in an SO–8.
The NCP1570 provides undervoltage lockout protection, Soft Start,
Power Good with delay, and built–in adaptive non–overlap.
