NCP1579  
Low Voltage Synchronous  
Buck Controller  
The NCP1579 is a low cost PWM controller designed to operate  
from a 5 V or 12 V supply. This device is capable of producing an  
output voltage as low as 0.8 V. This 8pin device provides an optimal  
level of integration to reduce size and cost of the power supply. The  
NCP1579 provides a 1 A gate driver design and an internally set  
275 kHz oscillator. In addition to the 1 A gate drive capability, other  
efficiency enhancing features of the gate driver include adaptive  
nonoverlap circuitry. The device also incorporates an externally  
compensated error amplifier and a capacitor programmable softstart  
function. Protection features include programmable short circuit  
protection and undervoltage lockout (UVLO). The NCP1579 comes in  
an 8pin SOIC package.
