www.DataSheet4U.com NCP1571 Low Voltage Synchronous Buck Controller The NCP1571 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 NCP1571−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 V2t control method to achieve the fastest possible transient response and best overall regulation. NCP1571 operates at a fixed internal 200 kHz frequency and is packaged in an SOIC−8. This device provides undervoltage lockout protection, Soft−Start, Power Good with delay, and built−in adaptive non−overlap.
