Introduction
The UCC2808APW-1G4 is an integrated AC/DC converter with an offline switcher designed for a wide range of applications. It is a highly reliable power supply solution that integrates a high-voltage start-up circuit, high-current low-voltage detection circuit, transformer driver, AC power rectification, power factor correction, and a universal input protection circuit. The chip can be used to construct multiple-output AC/DC converters for a variety of applications, including digital home appliances, industrial equipment, and embedded products.Application Field
The UCC2808APW-1G4 is very useful for a variety of applications, including digital home appliances, industrial equipment, and embedded products. It can be used to construct power supplies for games consoles, digital set-top boxes, DVD players, and LCD TVs. It is also useful for industrial applications such as LED lighting systems, battery chargers, and power adapters for cellphone and tablet chargers. In addition, the chip is suitable for embedded products such as routers, modems, and other small form-factor products.Working Principle
The UCC2808APW-1G4 consists of a high-voltage start-up circuit, high-current low-voltage detection circuit, transformer driver, AC power rectification, power factor correction, and a universal input protection circuit. First, the start-up circuit provides the necessary gate drive voltages and supply voltages to turn on the main power switch. Once the circuit is turned on, the transformer driver, rectification, and power factor correction circuits work to provide isolated and regulated DC voltages from the AC input power source. The high current low voltage detection circuit monitors the voltage level at the output and shuts off the circuit when the voltage level drops below the predetermined low voltage threshold. The universal input protection circuit provides protection against over-voltage, under-voltage, over-current, and over-temperature conditions.Conclusion
The UCC2808APW-1G4 is a highly reliable integrated AC/DC converter with an offline switcher that can be used to construct multiple-output AC/DC converters for a variety of applications, including digital home appliances, industrial equipment, and embedded products. The chip consists of a start-up circuit, transformer driver, rectification, power factor correction, and a universal input protection circuit, which work together to ensure reliable operation and optimal performance in an extremely wide range of input conditions.The specific data is subject to PDF, and the above content is for reference
