Datasheet Summary
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-...
