UCC3818N Description

Short technical summary and product information.

The Texas Instruments UCC3818N is an integrated circuit designed for active power factor correction (PFC) in preregulators. It utilizes average current mode control to shape the AC input line current waveform, achieving near-unity power factor and limiting line distortion. This device operates worldwide and offers features such as over-voltage protection and accurate power limiting.

 

The UCC3818N is built on Texas Instruments' BiCMOS process, providing benefits like lower start-up current (150 µA typical) and reduced power dissipation. It supports a wide operating voltage range of 12V to 17V and operates within a frequency range of 6 kHz to 220 kHz. The component is specified for an operating temperature range of 0°C to 70°C.

 

Designed for through-hole mounting, the UCC3818N comes in a 16-PDIP package. Its applications include PC power supplies, consumer electronics, lighting, and industrial power supplies, particularly those requiring IEC6100-3-2 compliance for supplies less than 300 W.
