Introduction

UCC2813DTR-4G4 is a high performance AC/DC power conversion device, which is applied in many application fields. UCC2813DTR-4G4 is a type of offline switcher, which helps adjust mains power to be suitable for all types of equipment. It uses a low-frequency transformation topology, helping to minimise size and cost and it has a wide range of output power rating from 10W to 100W. Working with global agency approved, UCC2813DTR-4G4 makes the implementation of global safety regulations much easier, making sure that it is a reliable and cost-efficient solution.

Application Field

UCC2813DTR-4G4 is mainly applied as a step-down converter in utility interactive AC/DC offline applications. For example, it can be used in many applications like Multimedia systems, Telecom systems, Industrial Automation, Lighting, Home Appliances, Security systems, UPS systems, Power Supplies or Point-of-Load systems. With its high performance, it is widely used in applications, replacing the bulky transformer and making them compact and efficient.

Working Principle

UCC2813DTR-4G4 works by using a low-frequency transformer as the power inductor for the switching stage, output rectification, and filtering stage. It converts AC mains to a DC output through the rectification and smoothing of the high-frequency AC pulses from the switching IC. The low-frequency transformer provides input power filtration and isolation between AC mains and the DC bus, and reduces the size and cost of the total system Design. The IC is configured capable to run the power conversion designs in two different ways. One is the CCM (Continuous Conduction Mode) and the other is DCM(Discontinuous Conduction Mode). For CCM mode, the input voltage is constant and the output load change will vary the switching frequency. In DCM mode, the output load is constant and the input voltage changes will vary switching frequency.

Protection System

UCC2813DTR-4G4 provides a wide range of safety protections, making it one of the most reliable and secure offline switcher. It has an internal Over-voltage protection function, which stops the power from fail from the output capacitors. The IC also has an over-temperature protection circuit to protect the device from high temperature. In order to prevent it from inrush current, there is a soft start circuitry and to provide a current limitation feature, there is an adjustable current limiting circuit.

Conclusion

UCC2813DTR-4G4 is a high performance AC/DC power converter device, which is used in many application fields such as multi-media systems, industrial automation, and home appliances. It uses a low-frequency transformer as the power inductor, which helps to reduce the size and cost of the total system design. It is a reliable and cost-efficient solution due to its wide range of safety protections and its ability to comply with global safety standards.
