Synchronous PWM Controller  
The NCP3030 is a PWM device designed to operate from a wide  
input range and is capable of producing an output voltage as low as  
0.6 V. The NCP3030 provides integrated gate drivers and an internally  
set 1.2 MHz (NCP3030A) or 2.4 MHz (NCP3030B) oscillator. The  
NCP3030 also has an externally compensated transconductance error  
amplifier with an internally fixed soft−start. Protection features  
include lossless current limit and short circuit protection, output  
overvoltage protection, output undervoltage protection, and input  
undervoltage lockout. The NCP3030 is currently available in a  
SOIC−8 package.
