The Texas Instruments UC3854BDWTRG4 is an advanced high-power factor preregulator controller designed for active power factor correction. It achieves near unity power factor by shaping the AC input line current waveform to match the AC input line voltage, utilizing average current mode control.
This controller operates within a voltage range of 10V to 20V and features a fixed frequency of 200kHz. It provides an average current of 250 µA and includes features like UVLO options (10.5 V / 10 V) and a high bandwidth of 5 MHz. The device is suitable for applications requiring line current distortion below 3% and worldwide operation without switches.
The UC3854BDWTRG4 is available in a 16-SOIC package, designed for surface mount applications. Its operating temperature range is 0°C to 70°C, making it suitable for various industrial and commercial environments. This controller offers accurate power limiting and improved multiplier linearity.
Key features include average current mode control, fixed-frequency operation, and a wide bandwidth current amplifier. It is an enhanced version of the UC3854, providing necessary functions for active power factor corrected preregulators.
