NCP1587, NCP1587A  
Low Voltage Synchronous  
Buck Controller  
The NCP1587 and NCP1587A are low cost PWM controllers  
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 NCP1587/A provide a 1 A gate driver design  
and an internally set 275 kHz (NCP1587) and 200 kHz (NCP1587A)  
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 NCP1587/A comes in an 8−pin  
SOIC package.
