Introduction

PMIC - PFC (Power Factor Correction) is a kind of power management IC (PMIC), which is used to maintain the power factor of an electrical system. PFC usually contains two main parts: switching regulator and filter. PFC is a highly efficient regulator that can improve the electrical efficiency of a system by increasing the input power factor, which reduces power losses and improves reliability. The UCC28063D is one of the most commonly used PFC ICs.

UCC28063D Overview

The UCC28063D is a PFC controller that provides a high level of immunity to line voltage input transients and offers low-noise switching mode operation. It is an ideal device to replace discrete circuity. It is designed to be used in a boost topology and is capable of providing up to 600 W of output power. It includes an integrated switch driver with 4.5 A peak current capability, thermal protection and undervoltage lockout functions. The UCC28063D includes all the necessary control and protection functions for an efficient and reliable PFC controller.

Typical Application

The UCC28063D is commonly used in LED modules, heavy industrial AC power converters, and SMPS (Switch Mode Power Supply) applications. Its high power efficiency and low-noise operation make it well suited for applications that require high-power performance without compromising the quality of the output signal. In addition, the device is RoHS compliant and is available in a space-saving 8-pin DIP package, making it ideal for space-constrained applications.

Working Principle

The UCC28063D works by sensing the input voltage and appropriating the correct amount of energy to provide a constant voltage output. The input voltage sensed by the PFC controller is used to control a switching regulator, which regulates and boosts the input voltage to a desired level and frequency. The PFC control IC then monitors and regulates the output current, switching the regulator on and off as needed in order to maintain the output power.The UCC28063D also includes an integrated switching driver which provides 4.5 A peak current. This enables the PFC controller to drive high power loads while providing a low-noise operation. The controller also includes thermal protection and undervoltage lockout functions, improving the reliability and safety of the output power.

Conclusion

The UCC28063D is a highly efficient PFC controller, capable of providing a reliable, high-power performance with low-noise operation. It can be used in various applications such as LED modules, heavy industrial AC power converters, and SMPS applications. The controller also includes an integrated switch driver, thermal protection and undervoltage lockout functions, making it a reliable and safe device.
