The Texas Instruments UCC28051DR is an active Transition Mode Power Factor Correction (PFC) controller. It is designed for low-to-medium power applications requiring compliance with harmonic reduction standards like IEC 1000-3-2.
This controller operates in transition mode, also known as boundary-conduction mode or critical conduction-mode operation. Key electrical specifications include an operating voltage range of 12V to 18V, a frequency of 200kHz, and a maximum duty cycle of 99%. It features overvoltage protection, peak current mode control, and supports flyback topologies.
The UCC28051DR is housed in an 8-SOIC package and is suitable for surface mount applications. It operates within a temperature range of -40°C to 105°C. The device also includes features such as two UVLO options (12.5V/9.7V) and a low start-up current.
This PFC controller is ideal for designs needing efficient power factor correction while meeting regulatory requirements. Its features facilitate a low implementation cost and improved transient response.
