UCC28070QPWRQ1 Description

Short technical summary and product information.

The UCC28070QPWRQ1 from Texas Instruments is a high-performance, two-phase interleaved continuous conduction mode (CCM) power factor correction (PFC) controller designed for automotive applications. This device offers advanced features such as feed-forward correction, frequency dithering for EMI reduction, and synchronization capability to an external clock.

 

Key electrical characteristics include an operating voltage range of 11.2V to 21V and an adjustable switching frequency that can be programmed from 30kHz to 300kHz. The maximum duty cycle is 98%, and it operates with a typical current consumption of 20 mA. The controller is designed for boost topologies and provides inherent current matching between phases.

 

Packaged in a 20-TSSOP, the UCC28070QPWRQ1 is suitable for surface mount applications. It is AEC-Q100 qualified for automotive use, with a temperature grade of 1, operating from -40°C to 125°C. The device also includes protections such as bias-supply UVLO, output overvoltage, open-loop detection, and open-circuit detection.

 

This PFC controller is ideal for designs requiring high power factor and efficiency in automotive power supplies, AC/DC converters, and other demanding applications where robust performance and compliance are essential.
