UCC28070DWR Description

Short technical summary and product information.

The UCC28070DWR from Texas Instruments is a two-phase interleaved continuous conduction mode (CCM) PFC controller designed for applications greater than 750 W. It utilizes an average current-mode PWM control with inherent current matching and advanced current-synthesizer current sensing for superior efficiency.

 

Key electrical features include an operating voltage range of 11.2V to 21V and a maximum duty cycle of 99%. The switching frequency is programmable, with the UCC28070 variant offering a range from 30kHz to 300kHz. It also supports programmable frequency dithering for EMI reduction, up to 30kHz.

 

This device comes in a 20-SOIC package with surface mount mounting type. It operates within an ambient temperature range of -40°C to 125°C. Protections include bias-supply UVLO, output overvoltage, open-loop detection, and open-circuit detection.

 

The UCC28070DWR is suitable for power factor correction in various power supply designs requiring high efficiency and stable operation.
