UC3854BDWTR Description

Short technical summary and product information.

The UC3854BDWTR from Texas Instruments is an advanced high-power factor preregulator IC designed for active power factor corrected preregulators. It controls boost PWM to achieve near-unity power factor by shaping the AC input line current waveform to correspond to the AC input line voltage.

 

This IC utilizes average current mode control, which maintains stable, low distortion sinusoidal line current without the need for slope compensation. Key electrical specifications include a supply voltage range of 10V to 20V, a startup current of 250 µA, and a switching frequency of 200kHz. The operating temperature range is 0°C to 70°C.

 

The UC3854BDWTR is housed in a 16-SOIC package and is designed for surface mounting. Its features include an integrated current and voltage amplifier, output clamps, and a 7.5-V reference. This component is suitable for applications requiring efficient power factor correction and low line current distortion.
