UC2854BDW Description

Short technical summary and product information.

The UC2854BDW from Texas Instruments is an advanced high-power factor preregulator controller. It is designed to control 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 controller utilizes average current mode control, providing stable, low distortion sinusoidal line current without the need for slope compensation.

 

Key electrical specifications include an operating voltage range of 10V to 20V, an operating frequency between 80kHz and 120kHz, and a typical current consumption of 250 µA. The device operates within a temperature range of -40°C to 85°C.

 

Packaged in a 16-SOIC (0.295", 7.50mm Width) surface mount configuration, the UC2854BDW is suitable for various power supply applications requiring efficient power factor correction. Its features include accurate power limiting and a fixed-frequency oscillator.

 

This IC is designed for world-wide operation without switches and limits line current distortion to less than 3%. It offers integrated current and voltage amplifiers, along with output clamps.
