NCP1588  
Low Voltage Synchronous  
Buck Controller  
The NCP1588 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 device is capable of converting  
voltage from as low as 2.5 V. This 10-pin device provides an optimal  
level of integration to reduce size and cost of the power supply. The  
NCP1588 provides a 1.5 A gate driver design and an internally set  
300ꢀkHz oscillator. In addition to the 1.5 A gate drive capability, other  
efficiency enhancing features of the gate driver include adaptive  
non-overlap circuitry. The NCP1588 also incorporates an externally  
compensated error amplifier. Protection features include  
programmable short circuit protection and undervoltage lockout  
(UVLO).
