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−overla...
