UCC28065DR Description

Short technical summary and product information.

The Texas Instruments UCC28065DR is an active PFC controller utilizing Natural Interleaving™ transition-mode technology. This device supports high-frequency switching up to 800 kHz, enabling smaller boost inductors and reduced EMI filter sizes. It is designed for applications up to 750 W and offers features such as audible noise minimization, brown out protection, and burst mode operation.

 

The UCC28065DR operates within a voltage range of 14V to 21V and has an operating temperature range of -40°C to 125°C. It is available in a 16-SOIC package and is designed for surface mount applications. The controller's transition control mode and input line feed-forward contribute to improved system reliability and efficiency. It also helps enable compliance with energy efficiency standards like EUP Lot6 tier II, CoC tier II, and DOE Level VI.

 

Key features include reduced current ripple for higher system reliability, improved input-current THD, and high light-load efficiency. The device also incorporates user-adjustable phase management with input voltage compensation and burst mode operation with an adjustable burst threshold. Sensorless current-shaping simplifies board layout and enhances efficiency, while inrush-safe current limiting prevents MOSFET conduction during inrush.
