NCP1570  
Low Voltage Synchronous  
Buck Controller  
The NCP1570 is a low voltage buck controller. It provides the  
control for a DCDC power solution producing an output voltage as  
low as 0.985 V over a wide current range. The NCP1570based  
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 V 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 SO8.  
The NCP1570 provides undervoltage lockout protection, Soft Start,  
Power Good with delay, and builtin adaptive nonoverlap.
