UC2854BDWTR Description

Short technical summary and product information.

The Texas Instruments UC2854BDWTR is an advanced high-power factor preregulator controller IC designed for active power factor corrected preregulators. It achieves near unity power factor by shaping the AC input line current waveform to correspond to the AC input line voltage using average current mode control.

 

This controller operates with a voltage range of 10V to 20V and a frequency range of 80kHz to 120kHz. It features a typical operating current of 250 µA and operates within an ambient temperature range of -40°C to 85°C.

 

The UC2854BDWTR is available in a 16-SOIC package and is designed for surface mount applications. Its features include a fixed-frequency oscillator, a voltage amplifier with soft-start, and line voltage feedforward.

 

This device is suitable for applications requiring efficient power factor correction, such as in power supplies for various electronic equipment.
