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-...
