UCC3817DTR Description

Short technical summary and product information.

The Texas Instruments UCC3817DTR is a BiCMOS Power Factor Preregulator controller. It is designed to control boost preregulators to achieve near-unity power factor by shaping the AC input line current waveform to match the AC input line voltage. This device utilizes average current mode control for stable, low distortion sinusoidal line current.

 

Key electrical specifications include an operating frequency range of 6 kHz to 220 kHz, an operating voltage range of 12V to 17V, and a typical start-up current of 150 µA. The controller features over-voltage protection and accurate power limiting. It operates within a temperature range of 0°C to 70°C.

 

The UCC3817DTR is supplied in a 16-SOIC package, suitable for surface mount applications. Its design is optimized for applications requiring IEC6100-3-2 compliant supplies, such as PC power, consumer electronics, and industrial power supplies.
