The Texas Instruments UC2854BMDWREP is an Enhanced Product Advanced High-Power Factor Preregulator designed for applications requiring near-unity power factor. This device utilizes an average current mode control strategy and operates in Continuous Conduction Mode (CCM).
Key electrical specifications include an operating voltage range of 10V to 20V and a maximum duty cycle of 95%. It features a high bandwidth current amplifier and integrated output clamps. The operating frequency range is between 80kHz and 120kHz, with a low start-up supply current of 300 µA.
This component is housed in a 16-SOIC package with surface mount capabilities. It is specified for an extended operating temperature range of -55°C to 125°C, making it suitable for demanding environments. The UC2854B-EP series is noted as Not Recommended for New Designs (NRND), though it remains available for existing customers.
Applications for this preregulator include AC/DC switching power supplies where power factor correction is critical to meet regulatory standards and improve efficiency. Its design aims to limit line current distortion to less than 3%.
