DESCRIPTION  
The UCC38050 and UCC38051 are PFC  
Zero Power Detect to Prevent OVP During  
Light Load Conditions  
controllers for low-to-medium power applications  
requiring compliance with IEC 1000-3-2 harmonic  
reduction standard. It is designed for controlling a  
boost preregulator operating in transition mode  
(also referred to as boundary conduction mode or  
critical conduction mode operation). It features a  
transconductance voltage amplifier for feedback
