NCP1570 Low Voltage Synchronous Buck Controller

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 regu.
