The UC2854BN from Texas Instruments is an enhanced bipolar CCM PFC controller that provides active power factor correction by shaping the AC input line current waveform to match the AC input line voltage. This controller utilizes average current mode control to maintain stable, low-distortion sinusoidal line current without the need for slope compensation.
Key electrical specifications include an operating voltage range of 10V to 20V and a frequency range of 80kHz to 120kHz. It features a low start-up supply current of 300µA and an operating temperature range of -40°C to 85°C. The device is available in a 16-PDIP package suitable for through-hole mounting.
This controller is designed to control boost PWM to achieve near-unity power factor and limit line current distortion to less than 3%. It offers features such as accurate power limiting and world-wide operation without switches. The UC2854BN is an enhanced version of the UC3854, offering improved linearity and a reduced AC offset in its multiplier.
While functional, the UC2854BN is noted as 'NOT RECOMMENDED FOR NEW DESIGNS'. Alternate parts with enhanced features and wider operating conditions may be considered for new projects.
