Introduction

The UCC28513N is a highly integrated power electronics controller designed to provide superior performance and efficiency in a variety of power factor correction (PFC) applications. This power controller is designed to be used in offline and online flyback, forward, and boost topologies. With its highly advanced switching algorithms and maximum frequency of 1.25MHz, this controller can switch at the lowest silence counts while still providing the highest levels of performance.

Features

The key component of the UCC28513N is its advanced 8-bit PFC core with integrated protection features. This core enables the controller to operate up to 1.25MHz and provides superior protection in over-voltage, over-current, and overtemperature conditions. The advanced algorithms and timing of this controller also allow for very fast PFC loop closure, providing improved system efficiency and reducing power losses.The UCC28513N also features a wide range of adjustable features, including peak current, peak voltage, overvoltage protection (OVP), and pulse frequency modulation (PFM). Additionally, the controller comes equipped with an adjustable soft-start feature and an adjustable start-up time delay. The soft-start feature is designed to gradually bring up the operating voltage in order to reduce the inrush current and ensure a reliable system start-up.

Application Field

The UCC28513N is primarily designed for use in high-efficincy switch-mode power supplies with power factor correction. This controller is ideal for consumer electronics, power tools, and other applications requiring high levels of efficiency and power factor correction. In addition to the consumer-based applications, the advanced features and high levels of performance make this power controller ideal for industrial, agricultural, and automotive applications.

Working Principle

The UCC28513N follows the standard power factor correction technique of sampling the input line current and modulating the output based on this information. This principle is somewhat similar to that of a voltage regulator, but with a few key differences. In a voltage regulator, the output voltage is regulated to a fixed value. In contrast, the output of a PFC controller is adjusted based on the sample current. This means that the controller is able to dynamically adjust the output voltage as needed in order to ensure the desired levels of power factor correction.The UCC28513N also features an adjustable universal voltage controller (UVC). This controller enables the user to adjust the voltage setting of the controller in order to achieve the desired output level. The adjustable UVC also allows the user to set the value of the reference voltage that the controller will use to regulate the output voltage.

Conclusion

The UCC28513N is a highly advanced controller designed for use in power factor correction applications. Featuring a wide range of adjustable features, high switching frequencies, an adjustable soft-start feature, and integrated protection features, this power controller offers superior levels of performance and reliability. Additionally, the UCC28513N is ideal for use in consumer electronics, power tools, and a variety of other industrial, agricultural, and automotive applications.
