The UCC2888D is an integrated circuit designed specifically for reducing the time to market in offline switch mode power converters and AC to DC-converter designs. It is part of Texas Instrument’s UCC family of high performance offline switchers and AC/DC converter designs. This IC has a wide input voltage range of between 17V and 85V and supports output currents up to 3A. The UCC2888D is well suited for a variety of offline switch mode power supplies including flyback, forward, half/full bridge, and push-pull configurations.

The UCC2888D is a highly integrated, self-biased, current mode switcher. It provides primary side regulation with the ability to adapt to wide variations in line and load conditions without the need for external components. Thanks to its low-maintenance controller and PWM with frequency dithering, the UCC2888D takes very little time to develop compared to competitive solutions, while also providing excellent stability and precise output control during dynamic load changes.

The UCC2888D also provides several features that make it ideal for AC/DC converter designs. These include support for programmable soft-start, accurate and precise current limit, high performance voltage loop, and frequency operation up to 500 kHz for higher efficiency. It also has built-in EMI filters, multiple protection features such as over-current protection, adjustable voltage reference, and flexible driver stages capable of driving a wide range of output devices.

Beyond the power supply design, the UCC2888D also helps reduce system cost by eliminating the need for optocouplers, snubbers, and other costly components. Its design also provides a high level of system reliability, with built-in thermal shutdown, current limit, and over-voltage protection features. All of these features make it one of the most cost-effective AC/DC converter designs available on the market.

In terms of application fields, the UCC2888D is suitable for a wide range of offline AC/DC converter designs including power supplies for battery chargers, ac/dc adapters, power inverters, LED lighting, and industrial motor control systems. With its high level of integration and performance, the UCC2888D offers the perfect solution for designs requiring reliable AC/DC conversions and fast time-to-market.
