UCC28061D

The Texas Instruments UCC28061D is a transition-mode Power Factor Correction (PFC) controller designed for applications requiring high efficiency and low audible noise. This IC is housed in a 16-SOIC surface-mount package, facilitating integration into various power supply designs.

Key electrical specifications include an operating voltage range of 14V to 21V and a maximum duty cycle of 99%. The controller operates at a frequency of 500kHz and consumes a low current of 100 µA. It supports boost topology and features like brown-out protection, enable functionality, and peak current mode control.

Designed for applications up to 750W, the UCC28061D offers features such as natural interleaving for improved efficiency and reduced EMI. Its transition control mode contributes to better light-load efficiency and design flexibility compared to traditional continuous conduction mode controllers. The device also includes overvoltage protection (OVP) with dual paths to prevent output over-voltage conditions.

This PFC controller is suitable for a wide range of power supply applications, including adapters, gaming power supplies, and home audio systems. The surface-mount 16-SOIC package is standard for many electronic assemblies, and the operating temperature range of -40°C to 125°C ensures reliability in diverse environments.
