UC2854BDWG4 Description

Short technical summary and product information.

The UC2854BDWG4 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, which maintains stable, low-distortion sinusoidal line current without the need for slope compensation. Key features include a high bandwidth of 5 MHz, low-offset current amplifier, and integrated current- and voltage-amplifier output clamps. It offers UVLO options of 16 V/10 V or 10.5 V/10 V and operates over a wide temperature range of -40°C to 85°C.

 

The UC2854BDWG4 is suitable for applications requiring accurate power limiting and world-wide operation without switches. Its fixed-frequency average current-mode control ensures efficient power factor correction. The device is available in a 16-SOIC package, suitable for surface mount applications.

 

This product is noted as 'NOT RECOMMENDED FOR NEW DESIGNS' by the manufacturer, and new designs should consider an alternate product. However, it remains available for existing customers.
