DESCRIPTION
The UCC38050 and UCC38051 are PFC
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
error processing, a simple multiplier 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.
