DESCRIPTION  
The UCC28600 is a PWM controller with advanced  
energy features to meet stringent world-wide energy  
efficiency requirements.  
UCC28600 integrates built-in advanced energy  
saving features with high level protection features to  
provide cost effective solutions for energy efficient  
power supplies. UCC28600 incorporates frequency  
fold back and green mode operation to reduce the  
operation frequency at light load and no load  
operations.
