Synchronous PWM Controller  
The NCP3020 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 NCP3020 provides integrated gate drivers and an internally  
set 300 kHz (NCP3020A) or 600 kHz (NCP3020B) oscillator. The  
NCP3020 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 NCP3020 is currently available in a  
SOIC−8 package.
