The UCC3819AD from Texas Instruments is an integrated circuit designed to provide active power factor correction (PFC) for power supplies. It achieves near-unity power factor by shaping the input line current waveform to match the input line voltage waveform. This controller utilizes Average Current mode control to maintain stable, low-distortion sinusoidal line current.
Key features include a wide operating voltage range of 10.8V to 17V and a switching frequency of 250kHz. The device is housed in a 16-SOIC package, suitable for surface mount applications. It also offers features like over-voltage protection and accurate power limiting.
Designed for world-wide line operation, the UCC3819AD is built on Texas Instruments' BiCMOS process, offering low start-up current and reduced power dissipation. Its leading-edge modulation technique helps minimize ripple current in the bulk capacitor, contributing to a more efficient and stable power system.
This PFC controller is ideal for applications requiring improved power factor and regulatory compliance. Its robust design and specific features make it a suitable component for various power supply designs.
