Low Voltage Synchronous  
Buck Controller with  
Adjustable Switching  
Frequency  
http://onsemi.com  
The NCP1575 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. It contains all required

circuitry for a synchronous NFET buck regulator using the V t  
control method to achieve the fastest possible transient response and  
best overall regulation. The NCP1575 operates at a default switching  
frequency of 200 kHz, but switching frequency is user−programmable

with an additional resistor between R

provides undervoltage lockout protection, soft−start, and built−in  
adaptive nonoverlap and is assembled in an SOIC−8 package.  
The NCP1575−based solution requires a bias supply of 12 V, and it  
can convert from a bulk power supply ranging from 2 V to 12 V.  
Conversion from bulk supplies greater than 7 V is best accomplished  
by using an external doubler circuit to raise the enhancement voltage  
for the external NFET switches.
