DESCRIPTION  
Accurate Internal VREF for Tight Output  
Regulation  
The UCC28810 and UCC28811 are general lighting  
power controllers for low to medium power lumens  
applications requiring power factor correction and  
EMC compliance. It is designed for controlling a  
flyback, buck or boost converter operating in critical  
conduction mode. It features a transconductance  
voltage amplifier for feedback error processing, a  
simple current reference generator for generating a  
current command proportional to the input voltage, a  
current-sense (PWM) comparator, PWM logic and a  
totem-pole driver for driving an external FET.
