  • Product introduction
The UCC28810 and UCC28811 are general lighting power controllers for low to medium power lumens where power factor correction and electromagnetic compatibility are required. It is designed to control flyback, buck or boost converter critical conduction mode operation. It employs a feedback error handling in which a simple command generates a transimpedance amplifier proportional to the input voltage current reference voltage generator, a current detector (PWM) comparator, PWM logic, and a totem pole driver to drive an external FET.

In critical conduction mode operation, the PWM circuit self-oscillating and conducting is being governed by a transformer zero-energy detector (non PIN) and shutdown is being governed by a current-sense comparator.
