NCP1587G  
Low Voltage Synchronous  
Buck Controller  
The NCP1587G is a low cost PWM controller designed to operate  
from a 5 V or 12 V supply. These devices are capable of producing an  
output voltage as low as 0.8 V. These 8−pin devices provide an optimal  
level of integration to reduce size and cost of the power supply. The  
NCP1587G 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 devices also incorporate an externally  
compensated error amplifier and a capacitor programmable soft−start  
function. Protection features include programmable short circuit  
protection and under voltage lockout (UVLO). The NCP1587G comes  
in an 8−pin SOIC package.
