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 8 ? pin 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
non ? overlap circuitry. The device also incorporates an externally
compensated error amplifier and a capacitor programmable soft ? start
function. Protection features include programmable short circuit
